>What would be interesting is if they bypass the video display output phase completely and render the finished framebuffers to memory... That's exactly what NVENC, Capture SDK, AMD's AMF, and Intel's QuickSync do. Just encode the framebuffer output of whatever game engine you're using with one of those API's. (And remember to make sure your game engine license allows you to use it that way. As always, if you use Unity, you're out of luck, they specifically forbid you from doing this.)
