I think the addition of physic engines (PhysX or else) is promising, but right now the big performance hit makes it a hight-end feature only; much like AA and AF when they were first introduced. I think many people will remember that is used to yield much better results to just increase resolution than enable AA and AF. With time I think it will slowly be introduced into more games, but I think it might require some "consortium" to standardize the programming API so game programmers don't have to code for every physic engine flavor (ATI, Nvidia, ...).
 

I just don't get it. Generic physics engines, used by Crysis and nearly all other physics-heavy games, runs off spare cores in a current quad or octo Nehalem without any performance hit. The idea of running physics off graphics card is just foolish. Graphics is in nature parallel, physics processing isnt, and should be handled by cpu instead. ATI and Nvidia are just pushing those because they make gpus and not cpus. That graphics card is under enough stress as it is, it doesn't need to try to run something that it's not good at.
 
Here are my vantage scores using updated drivers, 177.39 and PhysX.

ATI is AMD so they make both CPUs and GPUs. I think they try to offload part of the Physic processing to the GPU because the GPU already has physic instructions as the CPU has more "all purpose" instructions. There used to be a time when graphics were processed by the CPU as well, but it changed. Overall, I don't reject the physic idea, but as things are now, I wouldn't pay extra for it either.
