when i restrict renderer fps r_maxfps to 250, there are flickering in new version of r1q2.
the speed of my computer allow to render about 250-350 fps, and when i set r_maxfps 250 its decrease to 200-250 and flicker.
if r_maxfps 1000 its smooth. video is mobility radeon hd 4200 series. resolution 1366x768.
