Windows XP Desktop Screen Tearing (Vsync)

Hello, I got a sager NP2090 in August and I'm loving it, but can someone help me out with an issue I have in Windows XP. When I drag my windows around on the desktop, it seems as if v-sync is off and I see lots of tearing, even though when I play 3-D games, there is none. Screen tearing is even more noticeable when a window is resized in the horizontal direction. Is it a Windows XP problem or could it be something else. Can someone take their laptop and drag/resize, say their firefox window, and tell me if you get the same results. It also tears when I watch movies with lots of movement. I can't recall that ever happening to me on a desktop.

BTW, in Nvidia Control Panel, Vsync is Forced ON.

 

Try using ATI tool and see if you get any tearing or artifacts. Beings it is new you probably got a bad card...

 

I have an Nvidia Card (Nvidia M8600 GT). I don't think ATI tools work with Nvidia cards....

As for it being a defective video card, then why does vsync work flawlessly in games... Doesn't make sense.

 

ATI tool works with nVidia cards. All you need to do is run the scanner thingy, run it for a few hours and see if you get any artifacts / tearing. If so the card is !@#$ed.

 

Can you give me a link. But as I said earlier, ATI tools is 3D and vsync will work fine, its the windows desktop which is 2D has vsync off I don't understand why.

 

Sry, for reviving this topic, but I can't seem to find a solution to this. I really need help with this. Please.

 

Sounds to me like a driver problem, i would try a few different drivers first before thinking the worst. I don't have this laptop though so I cannot test first hand.

This sounds like a pretty serious issue and if more people were having it, I bet it would be all over the boards.

 

Ummm... I installed Sager's New driver yesterday, 156.10, and it did not resolve the issue. Then I tried one of the drivers from laptopdriver2go.com (176.xx) and that did not resolve the issue. But as I said earlier, there is no tearing for games. It works just fine, it's the videos that I watch in Windows that give me headaches. I tried using RefreshLock, that didn't help either. I'm 90% sure windows XP did not do that when I first installed it on this computer. I mean I've screwed around with drivers before and I guess I never paid attention to the tearing until recently. BTW, when I go to my display properties, it shows that I have dual screen (even though it's disabled in the NVidia Control Panel). One being my LCD Laptop screen at 1680 x 1050 and the other at 640 x 480. I did try using my VGA out once to my HDTV and it worked. Maybe that's a remnant that was left behind... No idea. But This is when it probably started, not entirely sure though.

 

I have the window tearing you mention also in XP. I did not have it in VISTA though. So It`s not you gpu. Because my desktop FX5200 has it also. It might be related to the hdd. Do you have a 7200rpm or a 5400 rpm one ?I have the 5400 rpm one...

 

Is the movement of the window slow ? If yes, than its some driver issue. Try using DriverCleaner before you reinstall the driver. Sometimes, left over files cause problems.

 

I have a 7200 rpm HDD in my laptop. Vista's desktop is hardware accelerated because it has 3D components (Flip3D) and XP doesn't. That could be why. I don't know what you mean by slow movement, cdahmedeh, I mean windows are responsive when I drag them, it's just that they tear when I move/resize them.

 

that sounds like a driver issue to me, just try using driver cleaner before installing the drivers. It should work.

 

Just went to 174.16 today, some of the tearing went away. Driver issue,no doubt for me.

 

I just want to stay away from Vista, I mean that's one thing that it has over XP, it's Desktop GPU acceleration. Is there a program that does that for XP? I'll Give Driver Cleaner a try. Maybe that will work.

 

Have you tried doing a clean install of windows, and then just installing the stock drivers in the correct order. Maybe try that if all else fails =).
