Game physics engines update their objects (acceleration, collision, constraints/joints etc) only so often at a certain tick rate to leave enough cpu time for other things. You can have very precise and realistic physics simulations already - they just don't run at realtime.

I don't think this is a solution for bad physics in games.

Whatever happened to dedicated physics processors? Can't we have a separate physical unit doing all those calculations in realtime?

>Whatever happened to dedicated physics processors?

Nvidia bought PhysX and stopped production of dedicated PPU. PhysX is just software now. And because it's proprietary (no AMD cards support/CPU implementation is slow) we don't really see games build around it.

GPUs or CPUs can be designated as PhysX devices within the NVIDIA drivers. Im not sure if that rules out using AMD devices but probably.
