View Full Version : vsync and fps

hey, a short question, is it really necessary to keep fps == refresh rate for vsync? i mean i want to limit fps to 60 to avoid some additional work. on my computer it works ok with vsync, my refresh rate is 75, i limit fps to 60 and see no tearing in fullscreen with enabled wglSwapInterval. should i expect same behaviour on most hardware?

If you're running at lower than your refresh rate you won't see tearing, but you will get irregular framerates, typically fluctuating between your refresh rate and half of your refresh rate.

thanks, that seems barely acceptable. however on my spec i see 60 fps without any deviation. looks like irregular framerate is hardware\driver - dependent;
