Nvidia Physx

[Bill Kunert]

I have an EVGA8800GS SC (G92), the latest Physx drivers and 177.66 installed. The Physx properties page says No Ageia Physx Processor Installed. My understanding was Physx would work on all G92 processors with enabled drivers. Is there something I'm not doing. I've tried 177.39, 40, 41 and they all show the same thing. Using XP home SP3.
Thanks

I don't believe that all G92-based cards are supported yet without hacking up the drivers, unless something has changed during the last week.

They've released drivers with physx support only for GTX 260, 280 and 9800 GTX. I don't think it's hard for them to release these drivers for other G92 cards, but it seems that Nvidia doesn't really wants it, because maybe they want us to get the more expensive cards. Who knows what's in their narrow minded heads.

The physx support absolutely works for the 8000 series cards, not positivie on the GS, but absolutely on the GT/GTX/GTX. Im using the 177.41 drivers on my 8800gt which enables Nvidia Physx. My guess is that nvidia Physx is enabled, but since you dont have the ageia card it says "No Ageia Physx Processor Installed"; my machine says the same thing. There's Nvidia physx and aegia physx, the drivers just enable your card to perform nvidia physx.

A good way to test it is to run the physics cpu test in 3dmark vantage. Before I grabbed the driver to enable physx i was getting about 7-10fps on that test. After enabling it I hit 100+fps on that test!!, my supposed CPU score is now 23000+

So 177,41 has Physix support for 8800 GT? Hmm, where have I been until now? Got to try them right away!

Just out of curiosity, has anyone used Physx on a G80/G92? I thought it was a mixed bag on the GTX260/280, sometimes better, sometimes worse. I'd think that with less stream processors it's be all the time worse? Maybe the frame rates would still be high enough to not matter, but I wasn't sure? Anyway, just wondering.

Just to clarify its does officially support the 8 series, you have to get a modified INF file to make the installer work. Am I allowed to post rapidshare links to modified drivers? If so I can post them.

SlowSpyder, the problem some encounter is that running physx on the gpu requires some stream processors, which means less stream processors for the graphics. So ideally you have one card "dedicated" to physx. As far as I know though only 3dmark vantage and UT2k7 support it at the moment.

Right, I thought sometimes the GTX260/280 ran out of resources when running Physx, so I wasn't sure how well a G80/G92 with ~half the stream processors would do with Physx enabled. If it drops from 100FPS to 60FPS, who cares, but if the drop is from 50FPS to 20FPS, then that's a problem. Anyway, that's all I was asking.
