i run a HD5770 1GB & 8800GT 512mb setup but GPU-Z down show OpenCL for the ATi Card nur Cuda for the Nvidia but it shows PhysX for both of them :laugh:

and yes my 8800GT is underclocked because it's only being used for Cuda/PhysX and h264/x264 decoding with CoreAVC in Media Player Classic.

When the Nvidia card is set to PhysX, CUDA isn't used. It's a primary PhysX card. PhysX showing up under an ATi card is new though.
 
right now the physx detection is system wide. if gpuz can create a physx context it will show physx for all cards

cuda detection does not work when there is no display attached to the card being queried. the underlying cause is that i havent found out how to create a cuda context on a specific device (if you have 2 identical cards in the system cuda cant give enough details which card is which)
so i go via d3d context and create cuda on top of that -> no display -> no d3d context -> no cuda
 
oki thx W1zzard, but what about the OpenCL thing, doesn't my HD5770 have that, or is it because i use a ATi+Nvidia setup? ^^;
 
did you install the ati opencl sdk thingie ? does opencl on ati work fine with other applications?
 
:ohwell: i installed ATi Catalyst 10.4, isn't that enough? maybe not :confused:

thx W1zaard that helped installing "ati-stream-sdk-v2.1-vista-win7-32.exe" now GPU-Z shows OpenCL ^^
