Hi, I have updated to 4.1.0 and I still have the same problem that UE4 is not using my dedicated NVIDIA video card.
Perhaps you can use the code snippet provided in this PDF of NVIDIA http://developer.download.nvidia.com/devzone/devcenter/gamegraphics/files/OptimusRenderingPolicies.pdf
Just put this somewhere in a global scope in a c/cpp file and Optimus should recognize the program as a program that requires a dedicated video card:
extern “C” {
_declspec(dllexport) DWORD NvOptimusEnablement = 0x00000001;
}
I have tried this in my own programs and it works. Of course these programs also run on my NVIDIA card when I tell them to through the control panel… so I don’t know if it will work for UE4.
