GT3-spec Physics and driver aids

Curious about how the physics work with the GT3 cars. As I understand it, Group GT3 regulations allow for Traction Control and ABS on GT3 cars. AFAIK the IMSA GTD class is the only GT3-using series that disallows driver aids. My question is do the physics for the GT3 cars take these driver aids into account? Are Traction Control and ABS incorporated into the GT3 cars without turning them on in the difficulty settings? Or would turning driver aids off make the car act like a GT3 car with driver aids removed? Conversely, would turning driver aids on make the GT3s handle like they had "double" driver aids? I'm trying to figure out which settings will give me the most authentic GT3 experience.

 

I believe that the most authentic experience would be with ABS on and TC on.

This is a quote from Aris: You could use some Traction Control. It's not an assist, don't look at it like that. It's how the real cars are used by the real drivers. Before you almost didn't need it, now you can use it as a part of the setup of the car and benefit from it, especially in tyre temps and wear.

When you start up a session in a GT3 car ABS is on by default...you must use ctrl+A to turn it off......TCS is off by default and you must use Ctrl+T to cycle through the levels of intervention, 1 being the most "intrusive".

 

So the GT3 cars, AS MODELED by AC, are modeled with TC and ABS off?

 

TC is off by default, ABS is on.

 

You mean level 1 TCS is the most active or the least?

 

Level 1 is the most active; it would be the setting that would be used in heavy rain or even ice for example.....

 

Right, but I'm not talking about in-game TC and ABS. I'm wondering if the physics modeling for the GT3 cars incorporates ABS and TC without in game settings, or if they are modeled as if the GT3 car had them disabled, so as to not interfere with in game settings.

What I'm asking is will a GT3 car in AC, with ABS and TC OFF in the in-game settings, handle like a GT3 car in the real world with ABS and TC disabled? Or would enabling TC and/or ABS in the in game settings give the effect of "doubling up" the effect of driver aids?

 

In the real world pretty much no GT car will have ABS disabled....go in game and turn off ABS and see if you lock up the tires...

edit...Protip...you will lock them up easily with ABS off

 

Good idea, hadn't thought of that.

 

I made the same question over simraceway sometime ago. What you want to know is if the regulated drivers aid are hardcoded into the car´s physics. I dont know the answer for this question in AC, but I went deeper in SRW to find the answer. That brought me to rfactor, which shares the same game engine and there, in every car´s physics, there is a penalty table, which can be configured for every drivers aids and steps. These penalties, AFAIK, were applied to the torque, lowering it the more "extra" driver´s assist that the user chooses to use. For example, the car in question was a 1993 Alfa Romeo 155 DTM. These cars were allowed (in real life) to run all sorts of electronics, so for those, TC 1,2; ABS 1,2,3; Stability 1... there were no penalties, but if you went Stability 2, you´d get "some" penalty in.

There is probably something similar in AC, for it makes much more sense to write the cars´ basic physics starting from the very basic.

 

TC is mainly there because GT3 cars are endurance cars and during a race it's all about tire management.

In this video Mclaren works driver explains the importance and use of TC(6:30 on):

 

Bang on. Articulated much better than I could hope for. Interesting info on the penalty tables.

 

That video explaining all the TC usage and ABS usage was brilliant. I think im right in saying we can control the amount of TC but can we control the amount of ABS similar to how it is in real life for the 12C GT3?

 

I would say so. It's just ABS on or off.

In the Zonda however even the ABS has levels(in early version it was only one too).

 

Thanks for all the info and great video in the thread. I knew the GT3 cars used ABS but never knew they used TCS.

If I was to turn TCS on when I'm in the car in AC, would my laps on RSR be considered "non-pro" rank?

 

This is my first post ever on this forum and i was wondering about the led lights in the Mclaren Mp4 - 12C GT3.
They don't react the same as in the real car. The Led's stay way up instead of dissapearing when you lift your foot of the throttle.
Any reactions of you guys would be appreciated.

And for the development team by Kunos thumbs up. I am having the most fun in simulator racing ever.

 

NO

Only if you use the game aids(selected from the menus) which are fake and not realistic.

TC electronics in car are realistic!

 

Not sure about the LED lights, will have a look when I next go on. What I do hope is that more data is added to the LCD though, I feel it helps with the immersion. For example if laptimes were displayed on the little LCD that would be awesome and maybe gaps or something like that.

 

Your lap will NOT be counted as "pro" on the RSR leaderboards if you use TCS.
