Select specific gpu for different applications on desktop pc

[nikita.bogoslovskiy13]

Hey there! On my desktop PC i have 2 installed Graphics cards (gtx 680 + gt 1030 as dedicated physx card). How can i select between this gpus to specific application (e.g run application 1 rendering on gtx 680, application 2 on gt 1030). Current nvidia drivers allows me to select gpu for opengl rendering, but all directx applications are rendering on gtx 680 by default and i cant select gpu for specific directx application like i can do it for opengl applications. Motherboard with Z77 chipset (p8z77 -v lx2). Why i can select gpu for opengl but can't select same for directx apps ?

I'm curious as to how come there is no option in the program rules to set a dedicated PhysX card for games such as BatmanAK and other games that do not scale well, but utilize heavy implementation of PhysX?

There is the option to set single card and SLI but nothing on PhysX let alone dedicate a card. It's baffling to me as to why do we have an option in the settings to set a dedicated card but not so for per program basis. It's quite annoying having to physically go everytime to change the settings when playing certain games and then changing back when playing games that utilize SLI. In most games SLI and PhysX work well enough but on PhysX heavy games they take too much processing power to maintain the two cards in sync which leads to stutters and problems including fps spikes etc..

Please NVIDIA if you reading the forums, add an option in addition to the already existing SLI/Single GPU program rule option to also include dedicated PhysX card (card1, card2) This would disable SLI automatically and set the selected card for PhysX use when a program is run that a rule is created for. Thank you very much!

seems its limited for backwards compatability

So does the physx drop down only include Auto, CPU & GTX 680?
