Any way to tell if my GTS250 is doing physx in Just Cause 2?
Hi!
I was running some benchmarks in Just Cause 2 with 3D vision and I noticed that while my GTX295 are working with a good load the temp on my GTS250 that is for Physx says just the same and when i am just browsing the internet.
I do have it selected as my Physx card so not sure whats going on.

Just Cause 2 does not do Physx, it uses Cuda for other stuff but it's not labeled as a Physx title.

Yeah and it seems CUDA cannot be offloaded to a secondary GPU like Phsyx is right?

From a mere tecnically perspective the answer is "yes, with CUDA you can select wich GPU do the calculation".

CUDA enumerate the device as device 0, device 1.... so, if the software "expose" this feature you can select your preferred GPU (maybe in the ini file of the game), if no, probably the app automatically choose the device or by default uses the device 0.
If the app autoselect the CUDA device you can force it to use a specific device by setting the compute mode of the two GTX 295 GPU to "Prohibited" (on linux there's a tool called NVIDIA‟s System Management Interface or nvidia-smi but I don't know if there is a comparable windows tool).
