Hi,
So in the Nvidia Control Panel, there is an option for physx...whether to enable/disable and what device basically runs the physx. For mine its set to Auto-Select but I'm pretty sure it defaults to using the GPU. Anyway I got interested and did some online surfing and found many opinions on this and apparently its a controversial topic. Many people say that you should let the CPU do it if its powerful enough to offload work from the GPU and allow the GPU to concentrate on other things, while others say the GPU is designed for it and therefore the GPU should do it. Well I've done some experiments...since none of the games I have support physx apparently I tried using a benchmark like heaven/supersonic sled/stone giant and I don't know if they support physx or not, but I tried and I didn't really see a performance change, maybe I didn't benchmark as consistent as I should have. But either way, the logical solution for physx in my opinion would be to let the CPU do it. If your CPU is powerful enough to handle it...why wouldn't you let it do physx so the GPU would have to work less and ultimately you can crank up other settings since your GPU doesn't need to worry about the physx. Why even get a dedicated physx card if you could just let your CPU do it.? Am I missing anything here? Thanks for any help or opinions on it.
