you hit the nail on the head there.
for a long time i have suspected this to be a major factor in the vehicle bugs, its as if the physics is out of sync with the rest of the engine or something.
i dont know enough about how it works under the hood though.
guess ill have to bite the bullet and download the nvidia branch and start hacking away again, someone has to do something. might as well try to help pinpoint the problem area(s).
