*HowTo*: ATI + NVIDIA PhysX Guide - Page 3

post #21 of 332

Hey, im so glad someone else is trying to figure this out, im stressing trying to get this to work.

Im using a hd4850 as my main card, and trying to use a 9500gt for physx. My problem is there is no option in the nvidia control panel to enable physx. Iam also using two monitors and i have tried plugging both cards into my secondary monitor, and also both cards into the primary monitor, yet no avail.

I have installed the up to date nvidia drivers and the physx drivers, and have even tried them on there own.

There must be a way to do this??

Using windows 7.

try enabling only the monitor connected to the NVIDIA card after installing all drivers, then check if you can enable physx, if you can (i was able to, maybe different drivers im using 181.71) then enable the ATI monitor as primary and try it out (mine will not let me open nvidia control panel after i have enabled ati card, but physx continues to function)

Im also doing this with triple4850 xfire

Eventually got physx to work, but this only happens when i select the secondary monitor(9500gt) as the primary monitor. When i set my main monitor to primary, the nvidia control panel fails to open. Nearly there!

FINALY I got it to work and I had to do a little of what you did. You select the Nvidia as primary and disable ATI then once the Nvidia Control Panel is open you enable the PhysX and then while keeping the CP open you change it up and make ATI primary and nvidia secondary. I am right now using my Ati in 16x and Nvidia at 4x, I can make it so its 8x and 8x by just moving the Nvidia up one but I don't think itll make much difference.

Also I did ALOT more than what I just wrote lol, I'm short in time right now just wanted to say it works for now and then later I'll post exactly how I did it. I'll answer questions till then.

Thanks Everyone!!!!!

Glad you got it Modoe

I installed a few programs from the nvidia physx pack including UT3 Physx mod, gives you 3 levels utlizing physx and it worked like a charm. Ran speedfan in my second monitor whilst playing the game and the 9500gt is clearly being used (changes in temp).

Think this shows that even though i cannot access the control panel after applying the ati monitor, the physx is still enabled prior to this. Seems that way anyway!

Yea I noticed it too, and vantage cpu marks just went flying off the roof, I got around 34000 not overclocked. Also I get some more fps out of some games as well like UT3 and even Crysis Warhead seems a little faster, gonna go buy Cryostasis soon I heard it uses heavy physx lol.
