Vsync ON frame skipping

post #1 of 4
Thread Starter 
Hi all. I've discovered a realy annoying and quite strange problem with vsync on some games.

Basically if i have vsync off everybody knows you'll get screen tearing which i can see.

as soon as i turn vsync on i get a frame skipping motion. I was playing around switching between on and off and noticed that when vsync is on i dont get the tearing but the frame skipping copies the exact point where tearing would normally occur creating the skip effect.

its visible on half of my games like cs:go and call of duty's but not bf3, bf4 that i can see anyway.

Here is a vid of it. Try to image where it skips thats where the tearing would be.

no idea why this is but i hope one of you guys do.

thanks

You can try frame limiting using Radeon Pro or Afterburner - for me it was frame limit = refresh rate - 1 - that might get you best of both worlds (not guaranteed to eliminate tearing completely)

You get a stutter with vsync if a frame takes longer than your screen refresh to render, for example if a 60hz refresh is 16.7ms and the frame took 16ms, it'd get displayed fine, but if it took 17ms then it'd be held in buffer til the next refresh cycle (~33.3ms total) and you'd get no new frame for that long which is percieved as a stutter, and that's why nobody uses vsync (aside from variable input lag which is annoying)

I did try frame limiting but it doesn't do anything unfortunately.

i've tried with both HDMI and dvi 60hz and 120hz it just wont go away.

could it be drivers or because the 290x is new out older games arnt supported as much?

any other tips?

could a reformat of windows on a SSD solve it maybe? thats my next upgrade.
