Talk:VSYNC vs WAIT/@comment-5334617-20141209183434/@comment-5334617-20141210171402

OK, we're in agreement that sync immediately after clear is not the best. Logically, the draw should happen immediately after the clear, so that the screen buffer is blank for as little time as possible. Given that, the two possibilities are:

sync-calculate-clear-draw

sync-clear-draw-calculate

In the first instance, the time gap between the sync and the completed image is longer than the time gap for the second instance. Since the purpose of synchronizing is for the display, it doesn't make sense to me that the time delay between the sync and the display being ready should be longer, or more variable, than it needs to be.
