Run PhysX on PC with AMD GPU as Primary and Secondary as NVIDIA?

[LOL_Wut_Axel]

Basically I'm looking to get an HD 7950, and I was just wondering if it was possible to use my GTX 460 for running PhysX on the few titles that support it, mainly Borderlands 2.

this has been discussed many times. yes its possible but you will have to use hacked drivers. the few people here that even fool with it will stop in and tell you what to do or you could just search or google it.

The power consumption of the 460 + 7950 wouldn't be worth the hassle for your electricity costs, IMO


I have played BL2 with a 6850 and a GTX 670 and prefer PhysX off due to the performance hit I get with PhysX.

Well I for one find having Physx on (Medium) to be a more immersive experience.

I'm running a Radeon 7970 + GTX 460 using the Hybridize method

The last patch that addressed Physx performance issues in the Pirate DLC, also fixed stuttering issues I was seeing in other parts of the game. The Hybrid Physx solution is working flawlessly for me now.

LOL Wut? Just messing around with different video card solutions, I'm currently using a GTX460 as my primary renderer and a 8800GT for PhysX in BL2 at 19x12 all settings highest/farthest with PhysX High. I seldom see framerates below 30.
Now you're talking about a GTX670 taking too high a performance hit? What does your framerate do? Go from 120 to 80?

Use that method, and I wasn't aware of the patch. I might need to take some time off from WoW and revisit Hybrid BL2.

A GTX 680 will snag and drop from 60 to ~50 (rare cases ~40.) This was before this patch mentioned above.

@ the above, maybe in single player.

Playing vs. the Bunkr with 1 other person last night was averaging around 30 FPS on a gtx 670 clocked at ~1240 MHz. 1980x1200. It was pretty annoyingly slow I guess it was dropping lower and jumping up a lot.

could easily be fixed if they give us an option on how many physx rendered objects stay on the screen... slow downs only happen when too much of those chunk of rocks flies all over you, plus the numerous monsters that are being rendered as well

Yeah, I've been waiting for the promised performance patch. I've been waiting to try it and suspecting that the 'performance' increase will come from reduced effects. I should take a lot of screenshots and go in the intense fights after the patch and try to compare if that's all they do.

Usually it's the colorful stuff that fills the screens like the elements and the explosions.
