why doesnt the need for speed shift demo use my GPU for PhysX?

post #1 of 10
Thread Starter 
i downloaded the demo and game runs okay but i think it would run faster if it wasn't using my CPU for PhysX i watched the CPU go from 34% to 100% during a race, and the visual indicator says its using my CPU is there a way to force it? i already dedicated GPU A for PhysX


thanks

Are you sure NFS uses Nvidia PhysX?

Remember, physics is not the same thing as PhysX.
