time usage debug, Flip[on]

Anyone have more info about this? It's under rendering. It has a ">" but when I click on it, nothing happens. Nothing in detailed info that I could see.

Periodically it will spike and UPS will drop to 40 from 60.

AFAIK, flip is mostly waiting for monitor VSync. You can turn off VSync and get a little more FPS, but with screen tearing.

--- edit ---

I.e. if your frame time is 15ms, flip will wait for VSync about 1ms and everything is fine. But if your frame time is 17ms, you will miss nearest VSync and flip will wait additional 15ms for the next, dropping your FPS to 30 instead of theoretical 58.

I disabled flip presentation mode. That seemed to fix it.
