Is it ever better to disable PhysX?

[Zathras]

I can't find a really straight answer on this via Google, but I was wondering if there are cases where you get better performance by disabling Nvidia's PhysX function on the GPU and allowing the CPU to deal with the physics. For example, you might have a lower-end or older NVidia card that technically "supports" PhysX, and a high-end multicore CPU. Anyone play around with this? I'm talking about a single-GPU situation, not SLI. Thanks for any thoughts.

I suppose in your case you will be fine leaving it to run because you got an ok card that will produce the goods.

Of course it is always subjective but by disabling physx you will get more fps in your games but I think that will only apply to the lower end cards.

You could try it and find out.
