I have this issue where sometimes when I play a game, I will get these faint horizontal lines shimmering across the screen. Usually this can be quickly fixed by turning on V-sync. Other times it doesn't help at all. My card is a GTX285 and my monitor is an LG LCD 23", with a 2ms response time. Sometimes I wonder if my monitor is too fast for my computer, or vice versa. Any thoughts on fixing this problem would be apprecitated .Thx
PS: More description on the problem. It doesn't affect the color at all, it more like an overlay. Like you looking at a recording of the game through an old movie projector. In some games it actually makes it look better, which is kind of cool. (Alice, Murder on the Orient). Other games it just messes with the graphics (Mass Effect, Risen)
I'm getting the exact same problem and v-sync does fix it. My graphics card is a 250 gts and my monitor has a 5ms response time, I don't think your monitor is your issue. It may be more to do with refresh rates because v-sync fixes it.
If you guys find a fix for this it would be greatly appreciated.
