PhysX support. Driver? Wine?

So I'm playing mirror's edge and the difference between enabling and disabling PhysX is massive - mainly due to the fact that it's trying to use my CPU rather than my GTX 680 graphics card.

Installing physx via winetricks made no change to performance so I have to ask: Is lack of working hardware physx support a result of lack of wine support or a lack of nvidia driver support?

(I'm using 295.40 proprietary nvidia driver)

There is no GPU accelerated physx in Wine. Under the hood physx can either use CPU or GPU. When it uses the GPU it uses cuda. This doesn't work on Wine (physx CAN'T use the linux cuda runtime), so physx just uses the CPU.

I see, getting around this would require a new driver for physx for linux and then hooking physx in wine to that driver yes?

I take it that's just a tad beyond the scope of wine? ;P

Yes, and this is how Wine uses many devices.

It is up to the folks at physx to do this.
