I am running windows xp nvidia 7600gs, with the latest drivers. Forced Vsync option enabled. I get 100% vsync when I move windows around rapidly and take screenshot.
I get 0% vsync doing same thing on latest kubuntu, with latest proprietary nvidia drivers, and open source "nv" driver, with all vsync options enabled. Strangely, I do have fps cap at 60 fps on glx gears. Yet applications visibly tears apart if I move them around too fast, movies also tear apart mid frame, even though my pc is more than fast enough to handle full hd video playback without tearing on windows xp. What really is the issue perhaps might be, there is no concrete way of testing if vsync is working besides high speed window movement and printscreen. Most other bugs are easily verified, yet vsync is hard to confirm on a stationary screen. Anyone care to develop a program that reads the framebuffer and determines if vsync is working?
