NVidia GTX 275 for dedicated Physx

RCoon · Jan 5, 2013, 07:35 PM

Just added a GTX 275 to my system and run the correct software hacks to run it as dedicated physx, and verified with GPU-Z. However every single game is trying to run itself using my GTX 275 instead of my 7950's in xfire. I have the two 7950's in the top two slots and with the DVI plugged into those, and the 275 in the bottom slot with nothing but power going to it. I've run MSI Kombustor and both 7950's take 99% load but the physx is still being run from the cpu, the same with fluidmark.
I have run the batch file with the Hack to set Physx to GPU instead of using nvidia control panel, as that simply says there is no attached GPU (though device manager shows it up.)
Only realised this when i tried to run metro 2033 and it said i need shader 3.0 support -_-
I have uninstalled and run driver sweeper and reinstalled but with the same results
NEED HALP

You might want to go here mate. I apologise for having no help for you but all the tricks are in this forum.

Games that use CUDA (Metro 2033 being one of them) will not work with a dedicated PhysX card, due to this being a PhysX mod, not a CUDA mod. CUDA is not supported.

So i simply cannot play metro 2033 when i have the extra card installed? Also why would kombustor and fluidmark not use the GPU either for physx?
Also Windows Aero has been disabled.

Kombustor doesn't use PhysX as far as I know. You may have to mess with extending your display in display properties. Try "connecting via VGA" even though it's not hooked up to a cable.

That's only for Win XP, 7 sorts that stuff out for you

No it really doesn't. You may want to try using this PhysX system software if you aren't on it already: http://www.ngohq.com/home.php?page=F...eme&dwn_id=765

You also may want to search for the particular game you want to run PhysX in and see if any files need to be removed/changed within the game folder. For example you need to remove some PhysX files in Borderlands 2 to get it to work.
