I'm not sure how long it's been like this, but the Physx setup on my PC is poked and I'm running out of ideas to try fix it.
Up til recently, I was running a 8800GTS G92 512mb (most recently with 252 and 260 forceware drivers
), and I wasn't aware of any problems because that card couldn't really handle physx in games very well anyway.. I got a EVGA GTX275 SC 896mb card the other day, and I wanted to compare physx performance (amongst other tests) between the two cards.
Anyway, no luck... "Ageia PhysX (32-bit)" in my Control Panel tells me there's no Ageia PhysX processor found; this I do understand may mean there is no Ageia-branded PPU in my box, which there is not. But GPU-z also tells me Physx is disabled, and FluidMark runs the test with software physx.
System restore is not an option because I clean up restore points regularly and I don't know when this started. I have tried cleaning my system with Driver
Sweeper then reinstalling both 260.99 (with Physx 9.10.0512) and 270.41 (with Physx 9.10.0514) drivers, but nothing seems to fix it.
Also, I know it is not the graphics card, because when I put my 8800GTS back in, it does the same thing. I know for a fact that card's PPU still works fine, I had used it many times in test applications, just not for games.
What am I missing here? I don't see any logical reason for Physx not to be working... I'm using less than 40% of my GPU (EVGA Precision OSD) with Mirror's Edge maxxed out, I want to see if it can handle the Physx side of the game. Edit
Sorry, I meant 270.61
, not 270.41
