I've discovered ways to route GPU output on Linux systems, especially with Ubuntu and Mint. The technology now supports this level of flexibility. My setup includes a Linux Mint host and a Windows 8/10 guest, with an i7-5820k CPU and ASUS X99-A motherboard. Both GPUs are GTX 970s. I need to: 1) Run the guest inside a window on the host for Unity-like experiences; 2) Send part of the GPU output to the guest; 3) When the guest shuts down, bring the passed-through GPU back to the host for compute tasks. I often want to game but also need full access to CUDA cores during work. Some sources suggest a single GPU can be made appear in windowed mode, though I'm not sure if this works reliably. A video on YouTube hints it might be possible with windowed rendering, but I haven't confirmed recent improvements.

I've been a bit away since you shared this, but I wanted to check if you reached your target. I used a single monitor that functions well but has some frustrating problems requiring fixes like a second keyboard or HDMI cables when connections fail. Finding a way to enable windowed mode would be ideal—it would let me work smoothly on the OS I prefer, stay productive, and have gaming power ready whenever needed.
