Devastator

I tried trick with display, but it didn't help. 197.45 refuses to install. I tried another ridiculous workaound: manually instaled legacy video adapter, replaced its driver with nvidia one, but it didnt help either. So i decided to make a deeper investigation. Took out ati and left only nvidia in main slot. Purged ati drivers, then installed nvidia 197.45 driver, installed 10.0513 physx. Then turned gpu physx on in nvidia control panel, checked GPU-Z: physx on, cuda on. But when i run fluidmark it always uses cpu for physx, no matter what i do, i even tried apply physx mod on it, but it didn't help. Perhaps this is somehow connected with internal hd3300, but it's turned off in bios.

it's working fine when used alone

Windows 7, and biostar ta790gx a3+

I've tried 197.45; 257.15; 260.99. the problem is that i can't install them because driver installer says "there is no nvidia card in the system" (but it's there and is working fine when used alone in main slot). It also does not appear in device manager as any kind of device. I also tried deleting all drivers with driver sweeper in safe mode, but it didnt help. Tomorrow i'll try driver from the first post, but i think problem is somewhere else.

(offtopic)Competiton is a good thing, overall. If one will have full monopoly.. but anyway this *situation with physx makes me outraged. I played bioshock 2, and after i finished it on ati, my friend asked me "so, how did you like physical water?". For god sake i've bought "the fastest gpu on the planet" and it does not support physx because some clever guys have monopolized it. what next? we will have two set of games, one set for ati and another for nvidia, and even more some games will run only on intel and some only on amd, and some only on nvida with amd cpu ,and so on, and we are gonna end up with the room full of cases, each one for playing specific game, wonderful! (sorry for offtopic) So, anybody have any ideas ho can i install nvidia drivers and make physics work?

Hi guys! Thanks for guides in first place! I've Sapphire hd 5970, and recently bought 9800 gt to try if for physx(i guess 60$ for it was a great deal). When i run nvidia driver it tells me that there's no nvidia card in the system. I tried some workaround - put out ati, installed nvidia drivers, put ati back, installed physx, applied patch. It's not working, i mean nvidia card is still not visible. I tried different drivers but with the same result. May be problem is with my motherboard? I've Biostar ta790gx a3+ which supports only crossfire / hybrid crossfirex, sli is not supported. Is there any other option to make them work together?
