I everyone. I recently bought Metro 2033 and cant get hardware PhysX to run with my dedicated card alongside the Radeon 5850. Im using Windows 7 64 bit, and I have been using the PhysX mod (caked) 1.02, but the Steam PhysX update always invalidates my attempts. I have got the PhysX to appear turned on for the 8800 GTS in GPUz, but as soon as I run Metro, even if I launch it from the steamapps/common DIR via the executable the update seems to invalidate the PhysX capability. Fluidmark would use hardware up to the pointof the update. Has anyone got a link to the fabled PhysX mod 1.04 or a version which is compatibly with the new NVidia 197.## Geforce drivers? Or any suggestions?
