I only used 40fps as an example. I know you'd probably want 60fps, 30fps or 20fps (or possibly 50 or 25 if your refresh rate has more of a PAL bent) Here's an idea I am curious about now. If you can almost but not quite reliably generate full res images at 60 FPS, can you generate quarter resolution (that is, half the pixels on each dimension for a quarter of the pixels) at 240 fps, or does the overhead for each render outstrip the efficiency from generating fewer pixels? That is, how much of a fixed overhead for a frame is there, and can it be spread over 4 frames, with slightly offset camera?
