Interrupt GPU command processing when a frame's fence is reached. (#1741)
* Interrupt GPU command processing when a frame's fence is reached.
* Accumulate times rather than %s
* Accurate timer for vsync
Spin wait for the last .667ms of a frame. Avoids issues caused by signalling 16ms vsync. (periodic stutters in smo)
* Use event wait for better timing.
* Fix lazy wait
Windows doesn't seem to want to do 1ms consistently, so force a spin if we're less than 2ms.
* A bit more efficiency on frame waits.
Should now wait the remainder 0.6667 instead of 1.6667 sometimes (odd waits above 1ms are reliable, unlike 1ms waits)
* Better swap interval 0 solution
737 fps without breaking a sweat. Downside: Vsync can no longer be disabled on games that use the event heavily (link's awakening - which is ok since it breaks anyways)
* Fix comment.
* Address Comments.
