First of all, thank to everyone for answering, and for AndroidXP:

Ah that's what you mean, I recall seeing that, too. It's probably the torque the engine exerts on the car body during acceleration, exaggerated by lag. Looks quite silly. :twirl:

That's not it either. - these "forces" manifest themselves even when there's absolutely no acceleration involved. It looks quite silly. And makes driving impossible - all the self-jumpin'n'self-bumpin makes the car loose grip. Is it a kind of bug? I really see no logic in blaming my slower PC (AMD 1200, GForce 2 Pro, 256 DDR) - wouldnt that "slowness" be affecting framerate or graphics? It doesnt. It makes up forces...I just hope someone with the same experience bumps into this post...

I dont use a wheel, i play with keyboard, or keyb/mouse. Well, its probably my PC, its a little older, but i still dont get it. I mean, the graphics look fine, the framerate's ok...one would expect that these things would break up on slower PCs. But this was unexpected - my PC is making up forces? If someone has had a similar problem, please help. Thanks

My car has these weird "twiches", it moves and jumps a little when in place, it looks like someone invisible is shaking it! It looks freaky. It does this even in the garage menu, not just on track! And these weird forces affect the car so much its impossible to drive. What could cause this weird physics problem?
Im running LSF S2 alpha demo.
