How do you mean switchable graphics? is there a normal setting this is called? This doesn't have any integrated graphics on board, and there is no other video card, so this is the only video card present

Yep. I have both set to enable, exactly like your photo. Threadripper 5975X, 128GB, RTX A5000, Win 11 Pro

I'm having an unusual problem. Running Mastercam 2024, new Quadro RTX 5000 card. When I run Mastercam 2024, all the processing seems to go to the CPU, the GPU just lays absolutely dormant. I've went to the advanced configuration tool in Mastercam and Hardware Acceleration is enabled. I have the latest Nvidia Quadro drivers. But 0% usage on my GPU. I go into the Nvidia control panel, it shows Physx enabled, everything set, and I've got the base profile where everything goes through the CUDA on the RTX; there are no other graphics cards installed, etc. I also setup an application profile for Mastercam that says: use the GPU. None of this seems to make any difference. Running Win11 Pro, Threadripper 5975WX CPU, Quadro RTX5000. I've debated whether or not this is a Windows 11 thing and if I should drop to Windows 10. Right now I'm open to any suggestions.
