What it does is uses a PCIe pass-through GPU to render the output, but instead of sending the actual video result to the actual GPU output (and thus, needing to switch input on your monitor), it renders from the GPU into a shared memory buffer which the host can display (in a window, or full screen). So it sortof works like remote desktop, but lower latency and full resolution due to using a shared memory buffer instead of TCP.
