Excessive Screen Tearing?
 

I got a new videocard about a month ago, an eVGA 6600 GT AGP to be exact, and lately I have noticed large amounts of tearing on the screen while playing games, namely WoW and Doom 3. In Doom 3 it gets so bad that I can't turn without seeing screen tearing. I'm not quite sure why this started happening in the past week or so, as I haven't noticed it in this amount before. Would this be a video card problem or a monitor problem? I have an LCD monitor that is 4-5 years old and I've felt that it's starting to act up lately, somewhat faded areas in places, etc., and so I'm at kind of a loss as to what to do. Thanks for any help you can provide :)

You just need to turn Vsynch on in the game options. That will make the video card limit its output to what your monitor is capable of displaying and eliminate the tearing. This normally causes a slight performance hit, which is why the default is "Off" on most new games. To avoid the performance hit, you'd probably need a monitor capable of a faster refresh rate.

I agree with Blaspheme's post. I have seen this same problem, not in new video cards, but with old monitors. It is more common in LCD monitors because of the way/speed that LCD monitors draw the screen.

Thanks a ton guys, I'll look into it and see what happens :)

Well I turned V-Sync on with both Doom 3 and World of Warcraft, (WoW actually already had V-Sync on) and there was an improvement in Doom 3 but not so much in WoW. There's still some big tearing that's kind of annoying. Think it could be a monitor issue? I'm really hoping it is and not a video card issue hehe.
