Yeah, but if I anderstand corectly, when moving the window, cpu usage
rised (sane) *and* FPS raised (completly insane)!!!
But talking about sane.... specialy when hardvare suported, shuld not GL
be able to synk FPS with the monitors vertikal refreshrate (if it can be
reached).... Seams like a complite waste of cpu cycels to produce more
frames than the monitor can show - and can reasnobel only give worse result!
