What is wrong with the kerb and grass physics???

I've been racing in iRacing many hours, aswell as on Assetto Corsa and Rfactor2. Trying to jump in to this game which is really cool in terms of graphics and sounds. But what is up with this games physics? I never felt like that before in any other game while going on through the kerbs, even on very little ones. It just does feels wrong. Car decides to suddenly start bumping while going over any kerb in any car setup. Car usually becomes impossible to control at medium speeds cause of this. Same thing applies when you just run out of track a little bit while going on a fast-medium speed. Car just stups bumping over and over again meaninglessly and finally ending on a spin or a direct hit to barriers. I wonder does anyone else feels same like me? I am hardly frustrated with the physics cause of this thing so far...

Am also of the opinion that not everything is correct with the driving physics. Because as you can see in the videos, the car slides off the body and turns. Would have to pass in the F1 then yes and this does not, in addition, the F1 car's faster than the GT3 series, so it would have to come even more.

Soften the suspension. Base setups in ACC are different from Iracing. Look at footage of the huracan in real life. They don't set them up too differently from ACC. Kerbs are literally designed as a deterrent. They are meant to make you NOT want to drive over them. The goal is keep people away from the edge of the track. Id suggest practicing running over them at lower speeds.

Or most likely the cause, turn down your FFB. You probably have it set way too high because you think it's cool and it likely makes it hard to go ever a kerb while keeping the wheel straight.

Exactly, more than thousands of kilogram car slowing down and then spinning back like that over and over again... That's something you can't see on AC aswell.

You guys are confusing the game not reacting how you want with how they should. Big difference guys. It doesn't matter what AC does or Iracing does. It matters how real ♥♥♥♥♥♥♥ cars react.

Why do i have no permission to delete those garbage comments from my discussion? I don't know where these people coming from and why are they trying to distribute it.

I have actually read some of the comments and they clearly explain why its happening with your vehicle,
Maybe you should re-read them or go to the official AC forum.

Did i said anything negatively about them? Maybe you should re-read too.

This is steams forum. Not yours. They and they alone get to dictate who can say what.

Hello guys, here is another video of mine getting rekt by another kerb in Zolder. I have been taking this kerb like 10-20 times before this happens without almost no problem except a few times with a little effect but ending with no problems. As you can see im in a race, car behind me comes almost faster than me means i am not even fast than normal on this turn which is obvious. So my actual question is, what i did wrong than the other laps in this turn ending up in the walls.

Setup is the Aggressive setup with 60mm ride heights on both ends.

You ran over a line of three very high bumbs. Yes. That will happen. Dont cut that corner that much. You are the kind of driver that required those be out there.

In real life that would ♥♥♥♥ up the car. Those are just as bad as sausage kerbs.

Don't run over the sausages unless the wheel is straight and even then you shouldn't run over them. In the real world they could damage your suspension if hit too hard and they will upset the car which is what happened to you. I don't know if this will be implemented in the damage model in the final release but that would be great and its nice to see real world physics in action in the sim.

You can cut the curbing but should avoid the sausages this will help you to be consistent and reliable. They are actually there to enforce track limits. Also note your exits are many times more important than your entry for that chicane. If you're too fast on entry you risk compromising the exit of the chicane and not having the best line for the following corners and short straight which is also an overtaking opportunity so don't worry about how fast other cars are approaching. What's missing from the videos however is your braking point and that could explain why the cars appear to be entering the turn faster. Perhaps you're too early on the brakes.

With the other laps you got lucky and kept the car straight or managed to regain traction on the right front (which would have been airborne) before the right wheel lock could throw you off. If you want to run over the sausages when hot lapping go right ahead. For an hour long race I wouldn't recommend it unless you're a gambling man, at some point you're just going to hit the curb wrong by a fraction and the rest is history and like I said, if they introduce suspension damage from striking curbs too hard or too often then you're screwed in a race.

Take your time and practice what works. You've seen jumping the sausages doesn't work but it can be great for qualifying runs.

that's how it should be, I don't see anything wrong except your racing line

Thanks for the helpful comments guys, and i would like you to make a comparison with this video too. Is it the car making the whole change? As you can see in the video below Jaguar is running through this kerb without even having any problems.

It's probably something else hitting the high rise curb instead of your wheels. (eg. aero parts or the chassis itself) Which I already said in previous post (#22)
You'll also suffer from aerodynamic instability as your car's ride height change drastically when driving through bumpy surface.
And in this video you will find how high the zolder's curbs were, and how upset the car can be when do took them wrong.
