Posts de Aristotelis en foro oficial

Hola, como soy tan alcahuete de Kunos me parece buena idea abrir este tema con respuestas varias de Aristotelis Vasilakos en el foro oficial, van a variar entre los mas diversos temas, voy a empezar por la ultima y van a ser en ingles, el que las quiera traducir, ya sabra como, translate.google.com copian y pegan el texto y listo.

Aristotelis:
I'd like to say a couple of things regarding prices, sales and Steam…
Not because I own an apology or explanation to the usual trolls that just want to cause noise and feel glad if they can convince somebody with their loud mouths.
But because I think some of the many many intelligent people that have bought AC, would like to know and appreciate.

When we started selling AC Early Access on steam the initial final contents we had in mind were 5-6 lotuses, a couple of historic lotuses, 4-5 BMWs, the KTM, the tatuus, the P4/5 and the little abarth…and believe us, back then it was a massive effort for us and a big financial risk.

So we started selling on Steam normally and Steam guys contacted us and proposed us the first sales, just a a couple of weeks after we entered early access. We declined because we didn't want to upset simracers… they laughed at us and showed us some "500kg of graphs and case studies"… we declined… but at some point we accepted just out of curiosity. The sales have been such a success in just 24hours that we couldn't believe it. From then on AC has been a great success for us and those sales and the Steam ecosystem permitted us to get bigger as a team, and invest on the AC brand.

So now you simracers have Pagani's, McLarens (which at first didn't even wanted to talk to us), Ferraris with all their top models! Mercedes and Alfa Romeo's… You also got Spa Francorchamps laser scanned for free. Also many features have been implemented and AC continues to improve at a steady pace and will do so in the future.

Is AC perfect? Is KUNOS perfect? Of course not, not at all. But it is also very young. I'm sure you remember that GPL although with various versions of Nascar and Indycar behind it, only got Vroc as mod addon 2 years after its release. LFS got the amazing LFS World as a mod, again after its release. rF has a big history behind it from SCGT to various F1 series and so on… We are the new kids on the block and we need time to improve. It's not like that you get the code from the other amazing simulators out there and you add on it… you build everything from scratch and this takes time. Even some of the most "simple features" in the minds of simracers takes a ton of time to implement because of so many variables to test and verify.

Still, AC has things others don't have. Laser scan tracks, active aero, blistering and graining, a universally praised physics system, not saying it's the best, but it sure is good! A very open architecture for modders, an elegant UI and more, much more….

So we understand that you guys are asking for more because in the end, you like the damn game. We appreciate this and we try to improve.

We also ask you to think that Steam sales have been and will be a win for all of you. Some of you have been luckier than others, but you all won extra content and features that wasn't even planned… and you're gonna get even more free content and features in 2015… PLENTY of it.
If you think that most of you have been playing for more than one month… not a bad investment for around 34-40 bucks.

Thanks for your attention, your support and your enthusiasm.
Cheers!

Esto es con respecto a los "cambios" introducidos en la v1.0

Aris:
Everybody is slower with the modifications on the tyre model. It is as intended.
You shouldn't judge the quality of the handling of the cars or FFB with your laptimes, it doesn't make sense.
The whole new tyre model modifications have been made and tested in the past 2 months using MAINLY a logitech G27, because we know it's the most used steering wheel out there.

You logic of us trying to make the sim good only for Fanatec owners is flawed business logic. How much money could Fanatec possibly give us to make the sim Fanatec "friendly", while pissing thousands of Logitech owners that actually... you know... buying the game? It doesn't make sense really.

I suggest you forget about lap times, take your time, don't drive by "memory" but by feeling and enjoy the sim. You'll find that it's even more enjoyable and realistic now.

Esto es anterior, cuando salio la RC y la Ferrari 458 GT2, que todos decian que se podia hacer Eau Rouge a fondo, diferencia entre los tiempos reales, etc

Aris:
First of all, let me change the thread from critical which is not obviously. I love to hear you people discussing physics and driving, but labeling critical a thread like this is not a good idea.

Let me also let out AC for a moment so that I can simply give facts on real life races and eliminate my subjectivity on the AC part of the story. ok?
Let's go, Spa 6 hours 2014, Qualifying session.
Let's start with the weather at Spa 6 Hours: [Tienes que estar registrado y conectado para ver este vínculo] Practice/26_Meteo_Qualifying Practice.PDF
Ambient temperature was around 7-8°C
Track Temperature was around 10-9°C
Humidity was 91-87%, track status was declared WET.
Wind speed was 10-15kmh
2:30.556 laptime under those conditions, so comparisson with any sim that doesn't have rain is out of question.

So let's go on to Practice session 2 which had the fastests laps for the whole weekend.
[Tienes que estar registrado y conectado para ver este vínculo] Practice 2/26_Meteo_Free Practice 2.PDF
Ambient temperature was 11-9°C
Asphalt temp was 12-11.5°C
Humidity was 85 to 89%
Wind was 8 to 20kmh from north
Track conditions DRY
Now, DRY conditions with such humidity and knowing Spa, probably means that the track had tons of humidity and was also in green state. Spa is also notorious for low grip asphalt.

Now let's analyze how a car is setup for such races.
GT2 cars have 4 sets of tyres + 2 tyres (not a set, just 2 tyres!) MAXIMUM for the whole free practice sessions and a warmup if one is scheduled.
This means that during practice, qualifying and warmup the teams have 4 sets of tyres of just one compound, usually the harder one, to try. With those 4 sets, they have to setup the car for two different drivers and most importantly find acceptable performance for the least fuel and tyre consume possible.
Very important: The is no use of gaining 1 second per lap more if you have to stop one extra time than you competitors. The setup must be satisfactory enough for both drivers and deliver the best compromise in terms of laptimes and pitstops. This is not a "let's see how fast we can go flat out" setup.
Top speed. Cars are very restricted and race very close to each other. There's no use if you have half a second faster setup when everybody else overtakes you on the straights because too slow. Often the setup is made to give some more top speed to the cars, compromising absolute laptime.
BOP: Balance of Performance. All GTE cars have ballast and rear wing height modifications imposed by the Federation in order to balance their performance. No car is in perfect form during races they are all limited in one way or another, especially the ones at the front.

Let's analyze how drivers react and drive those cars.
The fear factor is almost bull****... no real driver thinks about dying... their main focus is being faster. BUT... there are many but's...
Test limiting is very harsh on drivers in the last years. They visit a track and have a total of 20-30 laps before racing.... that's on par with the laps an enthusiast manages to do on a track day... ridiculously low amount of time.
They can't setup their car 100% to suit the track, their style, their necessities. It's a "good enough" setup that has to satisfy both drivers...
Their driving style can't be flat out either. We talk with GT3/GT2 drivers to name a few, , Alex Balzan, Nick Catsburg, Stefano Colombo... great guys. I'd also like to remind you that Kunos doesn't have the budget to put such names on a payroll, but they are very polite and happy to talk to us about their experience.
On Spa they told us, "yes you could go flat out on eaurouge and blanchimont, but you don't want too. Your race engineer doesn't wants too. It's an unnecessary risk for 6 hours and puts great stress to the tyres and you want them to last as much as possible, so you lift a bit and go safer and the lost time on track you gain back from 1 less pitstop. On fresh tyres, low fuel you can go flat out anytime if you want, but unnecessary risk."
Traffic. There's tons of traffic during a GT race. LMP1, LMP2, LMGTE pro, LMGTE Am cars... all in the same track at the same time... F1 traffic is a joke in comparison.

There are many other reasons, like mechanical parts preservation and setup choices for the race weather...

As you can see, all of those reasons are completely different from the conditions we found when we drive on our simulators... any simulator. I'm not talking or defending AC here, I'm talking generally.
In AC you should set the track in green conditions, lower the temperature (and you'll still be 2-3°C higher temp than reality, we go down to 10 only), use only hard tyres and try 20 laps. You still won't be equal to the real conditions. Then you should try to not cause graining, blistering, flatspotting in the tyres everytime you go out for a fast lap.

But let's forget about all of this and focus only on the lap difference. Which if I'm right is about 3.5 seconds AC vs Reality. That's on soft tyres, proper setup, on the limit driving etc etc.
Spa is a big place, it has 15 turns. If you gain just 0.25 seconds (a quarter of a second) on every turn, then by the end of the lap you have 3.5 seconds difference. That's just gaining 2 tenths of a second on every turn, not calculating braking distances or acceleration and speed on the straights and "alien" drivers dedication to details and infinite experience.

Add all of the above... I think some interesting conclusions can come out. I'm not saying AC is perfect, but when comparing real life laptimes to a sim, ANY sim out there, you must be less superficial. You need to analyze all variables and go deep in the details. Screaming "sim X is 2-4 secs faster than a laptime in real life that I saw on a website" is simply misleading.

Este es una respuesta a a un post que dice: Donde empezar al setear la suspension:
[Tienes que estar registrado y conectado para ver este vínculo]


All cars in AC come with as close to the real life default setup as possible.
As such, follow this workflow.

Street cars
- Start with camber.
Maximize negative front camber on street cars. They are limited anyway for track use and the more you can use (negative) the better.
- Lower tyre pressures.
For track use I suggest pressures under 30psi, even under 25 psi for very light cars. Don't overdo it, it won't pay. I'd go 25-27 for heavy cars, 22-25 for light cars.
Play with a difference front/rear pressure to balance the car. The axis with less pressure will have better grip (usually, not a rule of thumb for exaggerated values)

You can then play with toe values later, but that's all really for street cars and all that you need.

Race cars.
- Understand the engine characteristics and work on the gearbox ratios to have the correct ratio for each corner exit/apex.
Usually 300rpm less than max torque revs for low torque cars, and 600-800rpm for high torque cars.
The gearbox alone can give you a second so to speak

- Check the Aero balance by modifying the wings. Once you have found a balance and drag compromise you're happy with, go back to the gearbox and fiddle again.

- Camber all around. More at the front, less at the rear. Race slicks can use tons of negative camber. -3.5 to -4 should be used at front. Rear around -2 but with exceptions from -1 to -3. As a rule of thumb, if the car has too much turn in oversteer, raise rear camber, but you'll have less traction.
If your turn speeds got higher after that, fiddle with the gearbox again.

If the balance is still not what you like...
- Play with the arbs. The explanations in the setup tool tips should be enough.
- Still not good? Play with the Springs.

When you have played with springs, you'd need to check the ride height and then go to the Dampers and fix any bad behaviors. Dampers is the most complicated thing to understand, feel and setup. Not easy to setup.

Everything you do on a race car setup, always start the cycle again. Don't change many things at a time. Ideally just a couple of click, try, understand, see what the clock says (ultimate judge) and start the cycle again.


Have fun :)

(ok enough time out from me, back to the drawing board, workworkwork)

Esta es una respuesta sobre un tema del manejo/comportamiento del BMW 1M (bien como para que 4p diga algo)
[Tienes que estar registrado y conectado para ver este vínculo]

Let's add a bit on the conversation.

Street cars always have tons of understeer when driven on the track. I mean turn in understeer, mid corner understeer etc. I'm not talking on purpose power oversteer. Although lately some special models tend to have more aggressive setups because of electronic assists. So if you go over the top, assists save you, if you disable them, it's oversteer, but those are really exceptions.

Why the full camber at the front (not always advisable at the rear)? The modern semislicks tyres that anybody can buy and many high performance street tyres, really love camber. A street car, can't have enough negative camber. It would go usually up to -2 or something, often much less. Those tyres would love to operate at around -3 -3.5 negative camber, especially on McPherson suspension geometry. So at any street car, the proper advice is, use all the negative camber you can get, you're going to have less than ideal anyway.

Why the lower pressure? All the cars have the original tyre pressure from the manufacturer. When the tyre will be hot, the tyre pressure will raise well above the optimum pressure. So for hard use it is advisable to have lower pressure. Why Hany is faster with original pressures? Many reasons... depending on track, car, driving style... or simply... despite of it he is still fast :)
If you are the average to fast guy and not alien, I advise 26-28 for heavy cars, 24-26 for lighter cars. Full front camber, raise the rear one too... and you will be faster, or at least control better the car.

So, about the specific car the 1M. Here's Randy Pobst impressions on the motortrend best drivers car contender article.

"The 1M is an improvement on the 135, which I've spent some time in, but NOT my favorite car. In fact, I hate this car. It won't turn. The thing I didn't like about the 135 was its mid-corner understeer, its reluctance to turn once it was in the corner, and the 1M still does that. And it's the primary thing I remember after driving the car. That it is very lazy on turn-in."

Does this means that Randy is god and he is absolutely right. No, of course not. But it does mean that the car has a handling that make some drivers feel what Randy describes. Others might drive differently and not feel the same characteristics.

Why Robin_NL car is not behaving the same and why he says the AC car is like on lower grip tyres? Robin often does trackdays. I know of no track day guy that hasn't done a little something on the car :) Shocks? Different tyres? Found a good pressure compromise? Who knows. He might even push the real car in a way and the simulated car in a different way, that is a common thing that can happen. Or obviously, AC car might not be that perfect. That can happen too and it is very probably. But unfortunately I need more hard data before I change something just from "feeling". Telemetry readings told us that the real and simulated car do very similar if not identical lateral and longitudinal g forces. So we must be close. But it's difficult to interpret telemetry to understand the "feel".

Why the OP says he has problems at high speed turns with snap oversteer? Wheel at high speeds the tyres overheat faster. If he is already pushing the car and has problems controlling it, then it is probable that the tyres are already overheated a bit and then at high speeds the car becomes very oversteery. The rest of the setup, short wheelbase and suspension geometry makes it a nervous car.

Again, I'm not saying the car must be perfect in the sim, but I'm pretty certain that it is pretty close. It's not totally bugged. So there must be other things that you need to explore to make it behave more like you'd like.

4P,

Acerca de los pianos de Mugello y en gral.

[Tienes que estar registrado y conectado para ver este vínculo]


So the kerbs issue is indeed a very complicated thing. We are well aware of it and actively looking at it but it's not easy to find a solution without maybe a complete rewrite of the tyre model (which means also a complete re calibration of all the cars in the sim...)

It's a combination of realism issues, tyre model issues, physics refresh rate issues and others.

First of all, in terms of realism. In real life driving over such a kerb (steps) is dangerous. Yes I'm aware we can find a ton of examples that cars drive over such kerbs without any problems... but that doesn't make it less dangerous. Drivers do use kerbs to make the cars rotate, so the effect of rotation is valid in real life too. Also the higher the downforce, the stiffer the car the more dangerous riding the kerbs becomes. Weight also is important part of the equation.

For example - I'm always referring to Mugello which has the most dangerous kerbs in the sim (and in real life) because you ride on them for a long time at a high speed- you can see porsche Cup cars riding them quite aggressively. GT cars riding them with some attention, prototypes almost not riding them and formula cars actually avoiding them. Yes I'm aware there are exceptions, but we need to see the broader picture.
So what happens is, the lighter the car, the stiffer, the more they avoid those kerbs.
Why this happens? The steps in the kerbs, create vibrations and constantly raise the ride height up and down. A light and stiff car will vibrate even more. This can create an effect called porpoising which make the cars very pitch sensitive and continuously changes their front/rear aero balance. Have a read here:
[Tienes que estar registrado y conectado para ver este vínculo]
Small note: How about cars like a Lotus 49 that has no aero? This is a very light car with very springy tyres, there you can have big effects of resonance.
So all of this happens in reality, but what about the sim?

I believe the effects of those specific kerbs in the sim are a bit exaggerated, although not as much as that discussion have led people believe. Still, an issue is an issue. Why this is happening then? First of all, I believe the physics refresh rate is the limiting factor here. The physics of AC are quite complex and I don't say this in a "marketing" way. They really are. The physics engine is perfectly capable of simulating porpoising, or resonance in the springs, tyres etc.. But there is a big limiting factor in sims (all sims) and that's the refresh rate of the physics engine. In reality the refresh rate is instant. Reality runs at infinite hz [Tienes que estar registrado y conectado para ver esa imagen]
In all sims, not so much, actually we are very limited. So what happens is that you get an event , say the tyre/suspension hits the first bump, some time passes and because you are travelling very fast your physics skip a couple of kerbs, then the physics refresh and you get a second bump and so on. The fact that you're missing some kerbs means that the car at some point will give to the physics a position that is not longer a smooth variation but a big spike. BAM! the physics updates and sees the big spike in ride height, forces, frequencies, everything... and reacts. And you get a handling reaction that is over exaggerated... the typical "WTF" moment. The faster you go, the longer you stay on those kerbs (which happens typically at mugello) the more exaggerated the reaction will be.
I have tried AC at 1000hz refresh and it was much much better because you could feel the situation getting worse gradually and react accordingly. At the consumer 333hz we have, you get a big bump and you better be fast reacting or else...
This is one of the paradoxes that a very complex physics engine can provoke reactions that sim unrealistic, but in reality the end result is very realistic if you think about it. The only problem is that you don't get any feedback before. You don't get any warnings, you just get the end result if in reality you didn't react at all in a situation... which is what happens.

Finally, there might also be something that makes the situation further more critical, and it could be connected to the tyre model contact patch, but Stefano is the right man to talk about it, as I might say inaccuracies that will bring even more confusion to the subject.

What do we intend to do to solve the issue? Not much right now. It is a complex problem that needs quite some thinking and work. We look at it, taking notes etc and thinking about it. But we also think it is not an emergency. We think that sometimes simracers overreact on issues that prohibit them to do "as they like", in that case driving over said kerbs. In reality if something goes wrong then you blame yourself and you don't do it again next time. In a sim, it's always fault of the physics and you keep doing it because there is no cost other than complaining [Tienes que estar registrado y conectado para ver esa imagen] You know what I mean.

So do I propose to solve the problem simply by not riding the kerbs? Yes and no. It's a challenge as in real life. Learn to workaround the problem. Make a better setup that helps you overcome it, and so on. Yes I'm aware that many people will be upset and think "hey you don't solve the problem, you choose to ignore it booooo!". But that's not the case. I really think of it as a real life problem. It's another problem that makes some drivers better than others, some engineers better than others and so on. I also think that even if we found a solution, the end result would be simply a better "feedback" of what the car is about to do, not that we could make a perfect cure, permitting everybody to ride those specific kerbs without problems.

aand... wow I wrote too much, hope I manage to stay clear enough to understand and that the reply somehow is satisfactory up to a point.

Cheers

Que es más o menos lo que pasa en la vida real. Me acuerdo por ejemplo, vueltas de qualy de Schumacher, donde el tipo te usaba cada centímetro de pista y pianos que podía. Pero en carrera, era mucho más conservador, solamente subiéndose a los pianos que no representaban riesgo (o riesgo bajo) de perder el auto.

Me gustó la respuesta que dieron, porque explicaron algo que estoy seguro la mayoría de la gente (me incluyo) no sabía. Yo creo que entre más entendamos las limitaciones de los simus, más tolerantes nos volveremos a cosas como estas. Lo que no descarta que los tipos traten de buscarle una solución al problema.

En mi opinión, podrían tratar de "suavizar" un poco los pianos. Es decir, hacer que los serruchitos sean unos milímetros más bajos. De esta forma, el desplazamiento de la suspensión va a ser menos brusco. Perdés un poco de realismo en el sentido que ya no van a ser idénticos a los reales, pero ganás por el lado de que los jugadores se van a sentir más cómodos cuando los transitan.

Si saben lo que es una falacia , no les tengo que explicar lo que es.
No es exclusivo de Kunos, lo hacen creo que todos ( salvo, tal vez la gente de Reiza).
Es claro ( al menos para mi) que tienen un problema de fisicas; que o no saben resolver ( cosa que no creo) o no tienen tiempo de resolver; pero definitivamente los formulas y cualquier auto se come los pianos de Mugello como si nada. Y no solo les pasa en Muguelo ,sino en muchos por no decir todos los circuitos ( oficiales y no oficiales).


Y con esto no quiero decir que el juego sea una mierda, ni nada por el estilo; tiene cosas buenas.
Pero lo que dice Aristotelis, es como que uno valla al medico porque le falta el aire , te revisa y te dice que no tenes nada. Si le decis , que te sigue faltando el aire, te responde ..... que te acostumbres a que te falte el aire.

pero esta bien explicado, es un tema de las fisicas, no pasa en todos los pianos tampoco, ni quiere decir que todos los pilotos no usan los pianos en los formulas.
es algo que pasa en autos de competicion mas bien, o suspensiones rigidas, porque con autos de calle no pasa.

en mi opninion tendria que liberar el refresco de las fisicas con un parametro editable en el arranque , entonces el tipo que tiene la pc de la nasa que lo ponga a 1000 mhz y el que tenga la comodore que lo ponga en 20 mhz y se atenga a las consecuencias de ese problema de refresco.

lo podes hacer, esta en un .ini, lee el post del foro oficial, ya lo probaron.. esta el link al comienzo del post

Con la ferrari s3 que corrimos la última oficial, en la s antes de la ultima curva, y una que se hace en 4° o 5° a la derecha,
según como entrabas al piano perdias el auto sin aviso. Siendo menos tronco que yo, me imagino que pasará menos

Le pasa a cualquiera Bad. Y con cualquier auto.
En IR pasaba algo parecido y le llamaban minas terrestres. pasabas por determinados lugares y salias volando. Despues lo arreglaron , pero nunca dijeron como.
En Valellunga tambien se nota mucho y en realidad en todas. En un principio creia que era un problema del track surface, pero ellos dicen que no.
Y no creo que sea un problema de refresco porque el resto tendria el mismo problema.
Calculo que algun dia lo van a resolver; pero debe ser bastante quilombo porque estan arrastrando este problema desde el minuto 0.

por que no crees que sea un problema de refresco? el tipo lo explica correctamente y asume con humildad que puede haber un problema.
los iRacing no dicen nada, cambian cada 2 meses todos los autos y esta "todo bien"

Primero, porque si fuera un problema de refresco, lo mismo tendria que pasar en todos los otros juegos, llamados simuladores.
Segundo; porque el mismo lo dice: Finally, there might also be something that makes the situation further more critical, and it could be connected to the tyre model contact patch, but Stefano is the right man to talk about it, as I might say inaccuracies that will bring even more confusion to the subject.
Tercero, que tiene que ver iracing en todo esto?
PD: Ademas, no explica nada y ademas no asume nada con humildad, simplemente es algo innegable.
Ademas no hay necesidad que explique nada. Con decir que ya se dieron cuenta y cuando puedan ( sin dar fecha) lo van a arreglar, sobra.
PD2: No se porque tenes la idea ( por lo que leo) que son un iracing fun y estoy para desfenestrar a AC y sus seguidores.
Yo no soy Diso.

ah bueno ;) pense que te habias contagiado :)
pero todos los simuladores tienen ciertos hz "asignados" a sus fisicas. quizas los otros simuladores lo corrigen de otra manera.
si bien fue una respuesta a un email, el loco posteo su respuesta en en foro oficial y Aristotelis tiene la humildad de responder y explicar de la mejor manera (para vos es mentira lo que dice, por lo que lei) un problema X que le presentan y cuando tiene tiempo de responder. Ganas seguramente tenga siempre ya que es un proyecto del que es parte y defiende lo que hace.
en resumen, puede ser un tema de los Hz o de la goma, no tienen prioridad en resolverlo, se sabe, pero tampoco dice que es asi y punto.

Haber Leo ..... el tipo esta haciendo las veces de relaciones publicas, RRPP o como quieras llamarlo.
Me imagino que deben tener un monton de mails por dia rompiendo las bolas con esto y aquello.
Simplemente dan una respuesta para dejar a la gente tranquila y ya.

excelente noticia!!! luego me fijo. Mil gracias che!

En el hilo de Project Cars en el foro de AC hoy encontre esta respuesta de Aristotelis:

Excuse me guys, I don't mind you talking about pCars or whatever other sim you like. I also don't mind that you are criticising AC, AC physics engine or whatever. All fine and good, please do continue.

I do mind though when the criticism is taking a trend that is single minded or even false.
You might have noticed that there is no sim that has "everything" or that simulates everything properly. AC has it's share. But I think it's not fair to say AC is worse than X or Y or Z sim because it misses a specific feature. I can list various features that other sims do not have, does that makes AC automatically better than other sims in your mentality? I guess not probably.

As far as I know, AC simulates various pretty unique features.
It has a very advanced aerodynamic simulation that is also easy to understand and practically unlimited. Do other sims have active aerodynamics? Do they a good number of telemetry inputs that can be combined in ADD and MULT channels to control such aerodynamic surfaces? Speed sensitivity stalling of diffusers? Asymmetric flaps? Hell you can even design an aeroplane in AC, I know, I have... it just doesn't turn yet
Do other sims simulate flat spots, graining (although limited), blistering and tyre wear through a virtual km system that encourages proper driving?
Do other sims simulate different ABS, TC levels and EDL differentials?
Do other sims support complex hybrid systems that can modulate power delivery depending on ADD and MULT configurations of various telemetry channels. Can they also use them as traction control if needed?
Do other sims support proper McPherson and multiple link live axle suspension?
Do other sims support 3 differentials AWD systems with front share? Soon to be active too?
Do other sims support a h pattern gearbox damage solution as ours?

I could go on, there are plenty others more or less important.

Even our "inferior" tyre model as you guys have named it, doesn't seem so bad in the end after all, as it is still one of the best tyre models to permit proper drifting which you might not interested but it is one of the most critical situation a car can do in terms of handling. I'm not talking about drifting with your steering wheel straight. You might like it, but it does not happen in real life, it's wrong. Yet some of the more "advanced" tyre models, do suffer from it. We really hurt our brains to understand and improve our tyre model to react great on all situations.

Is it perfect? Of course NOT!
I do love for example the rF2 multiple temperature simulation, it's better and I do love their live track tech, fantastic! But hey, they also had problems with temperatures, like going over 600°C at wet tarmac. We explode the tyre over 300°C. rF2 again just made an addition to their model that limits grip when the tyre gets positive camber. We had that for a year and a half so to say. I remember there was also an issue were the temp would cool down if you would burnout in reverse gear. Not sure if that was rF2 or another sim, but **** happens, those are complex things. I'm not targeting rF2 in particular, actually I love it, but all sims have issues because hey, reality is HARD to simulate. pCars have its own issues, iRacing too, LFS too... all of them. So as you can see, the situation is not black&white always.

I know for example that we have problems with high downforce load sensitivity on the tyres. It happens on very high speed turns. We know how to solve it and we working on it to make a proper fix that goes even further than a simple adjustment. It needs a complete remake of all the tyres of all the cars and it won't happen in a day.
I know we have issues with the SAT forces, we're looking on it.
I have a physics improvements list that is so big, Stefano was about to kill me, but he knows it too and he loves to work on such stuff, much more than AI and Multi. I'm pretty sure that's the same identical situation on other sim devs out there. On the other hand, I'm very proud of many unique features that we have already implemented in our sim, as I'm sure other devs feel the same for their own sim.

Do I sound defensive? Yes I actually am. But because I care and love our product and I know how much work we put into it. So when I hear lately so many inaccuracies I thought I should clear things up a little. It's easy to forget the things a sim does well, and only complain about whatever you might have focused in this specific moment.
