horozontal lines when playing games.

Hi, when im playiing pro evo 4, i get a horozontal line slowly moving up the screen that distorts whatever it is on. when its there, a few seconds later it appears again from the bottom rising up.

Any ideas?

Im using a radeon 9600xt, with a abit kn7-v2 and xp2400

tried using v-sync?

anything overclocked? (although its probably the v-sync prob)

That happened with me when playing the pro evo demo. Its when the fps go over the refresh rate and cause horizontal tearing I think. Try and set your refresh rate as high as your monitor can support or try v-sync (which capps the fps not to go over the refresh rate)

how do i use v-sync. nothing overclocked

go to ati control apnel
then go to the 3d options tabs. search around and youll find v syn. i can give you mroe precise directions if u need them but i will need to knwo teh catalyst version as everything changed with catalyst 5.2
