Chassis handling needs to improve.

Hi guys,

I love assetto corsa and i am looking forward to competizione.
The first videos of competizione look impressive, but you immediately see the cars chassis is way to "stiff". It looks still like you are kinda racing on rails. I think this is something the devs seriously have to look into.

Look at this video from Nicki Thiim, he actually raced in the Blancpain Gt series and is now an aston martin driver for the FIA world Endurance Championship:



He is not only a professional racing driver but also a simrace enthousiast, he is basically stating that assetto corsa has the better tire model then iracing, but the chassis handling isn't up to par. And i totally agree and from the looks of the videos it didn't really change in competizione. A shame really because it's maybe not that hard to improve this.

What do you guys think?

 

I wouldn't worry about it too much at this stage. It could be that the physics is there it just hasn't been implemented into the visuals. I think it's really hard to judge based on someone elses opinion of a work in progress.

 

I didn't know camera movement was in fact chassis flex.

Easy fix indeed. You can even fix it yourself in AC moving a few sliders.

 

In assetto corsa, you can't really attack the corners, it's offcourse noticeable in the physics. Its not only the camera movement. Maybe it's true that in competizione they already improved this, but I doubt it based on the videos. You would probably see this by the movement of the car, like in real life.

 

"Chassis handling" (what?)
"Driving on rails"
"Attack the corner"

I have personal definitions for most of those incredibly vague expressions a lot of people seem to enjoy using. Each real life driver probably also has his own definition(even if most of the time they will be incapable of puttting into vehicle dynamics terms what they really mean). Chances are everyone here has his own very unique idea of what that means.

You seem capable of combining these vague terms, videos and come up with an improvement suggestion for ACC. Ok.

But what EXACTLY you would like to be added to chassis dynamics?

 

We want WEIGHT TRANSFER.

 

I want 'Jax' as a driver or own livery

 

well, for weight transfer to happen, you need to turn off the Antivirus

 

Dont worry if it's implemented it will be implemented well and the implementation will therefore be implemented

 

I haven't used iRacing, though I do agree that the tire model in AC is better than the others I've tried. On the chassis side, I do hear it hit hard even with a high ride height.

 

This is all very confusing.

 

They're more or less the same, some detail feel more realistic, some may feel less realistic. It's mostly about how driving is like and attempted to base that handling and steering on it while glitching on it.

 

Then it just gets more confusing.

 

considering who's involved it could have been MUCH worse

 

thread is open.
its not the end .....

 

I think he uses the word chassis globally for the car structure, the suspensions and how the weight of the car is distributed, not chassis as just the frame of the car. In the video he never speaks about suspensions and other parts which are obviously working more than the actual chassis, he mentions specific parts like brakes and tyres but only calls the rest of the car "chassis" that's why he's probably using the term chassis for the overall body of the car. It's a metonymy, a synecdoche. GT3 are very rigid, there's a roll cage and the carbon body increases the rigidity so that the chassis doesn't deform and the suspensions do all the work and they're easier to control.

In the video he says what he likes in Iracing is the track furniture, objects around look like you're on the real track. In the end he says he prefers Iracing despite the tyre physics, so graphics and immersion are important for him. I can't wait for him to try the new Assetto Corsa preview at Spa and hear what he has to say, along with other endurance drivers. Only sprint drivers have tested AC Competizione in Misano and Nicki Thiim is driving in the endurance series. AC Competizione will have what he liked in Iracing, graphics will be better, tracks will have more furniture and physics will be improved thanks to the feedback from drivers and there'll be a ranking or rating system for multiplayer.

 

More seriously and as @Lord Kunos is active on the forum ATM, I am wondering how the chassis flex is impacting the physics? My guess is it can make small variation on the camber of tyres but that should be compensated by the suspension anyway. Or it can bring additional absorption of impact or weight transfer? But maybe it is so tiny that there is no point to try to simulate that part...

 

will there be birdies flying around and dropping there waste on our cars to add more ballast to the chassis?

 

that would be arcade.. you also need to consider the effect on lift and drag coming from it.
