January 5, 20242 yr I have a Windows VM on my unRAID server with the GPU passed through to it. I access the VM via Remote Desktop from my desktop PC running Win10. I'm trying out Stable Diffusion (Comfyui) on the VM, and am giving the VM two monitors via Remote Desktop. Anyone who tries out GPUs and Stable Diffusion knows that GPU processing power is a key factor. So my question is which GPU does the heavy lifting in the display processing when RDP is in use? While clearly the local desktop GPU must drive the monitors, does the GPU in the VM affect this in any way? Essentially I'm wondering whether using one monitor for RDP instead of two would "save" some of the GPU processing power in the VM for use by the VM.
