Have to tried borderlands with PhysX? Can you confirm any difference in performance? How about scaling with different resolutions?

I had no problems with a 5850 and 9600GT running together until I bought another 5850 for crossfire and setup an eyefinity system. I didn't bother troubleshooting to see if it was the crossfire or the eyefinity that was the root of the issue. I just decided to abort the whole PhysX hybrid setup since not too many games use it anyhow, and to me it's just not worth the aggravation. Besides, I'd rather have a powerful 3 monitor setup then something "ok" with PhysX in "some" of the games I play.

I think nVidia will end up killing themselves in that area anyhow. They're keeping the lid pretty tight on their stuff and not letting anyone else in on it.

I already had my physx card installed when I started playing Borderlands so I have no before/after comparisons but I know that I can play it maxed at 1680x1050 with no slow downs with physX enabled. I have a new monitor now (1920x1200) so I can try it out and see.

Im offically going to start trying this out now, as I've recently bought both Batman and Metro 2033 (today in fact). Those two PhysX games plus Borderlands will be getting much of my attention of the near future, so the next question is: Has anyone sucessfully tried just installing the Nvidia card for Physx using the "Broken" 256 drivers? I'll be going all out with this... Eyefinity @ 5700x1200 + PhysX.

Why? Do you think one or both cards will overheat?

no, just in case theres more borking of the speed fan profiles = dead cards

With both cards in ill probably use Rivatuner for the Nvidia card and ATI OVerdrive for the AMD video cards fan speeds.

sweet. just take some numbers for us with it enabled and disabled. you should see a difference. i mentioned left for dead in another thread, my frend swore for it lol. even tough it doesnt officially support physx.

So CM did this work for you loading the patch from the OP with your ATI card. I was about to try loading Forceware 257.15 with my GTX 260 and the latest drivers for my GPU ATI 5850. Apparently the 257.15 allows phyx to be enabled with an ATI card but the procedure isn't explained in the post I got the info from.

I'm going to give it a try right now I figure I can't to any harm. First I will try the 257.15 with the 260 without loading the patch from the first post. If it works I'll post here, otherwise I'll try the technique described in the first post and I'll post the results.
