Texture / poly "tearing" problem

I was wondering if anyone could help me out.

I've been playing Warcraft on this PC for the last year, all fine. Nothing has changed - I'm tech savvie enough to know what my pc is and isn't doing - but suddenly and seemingly at random, I'm noticing polygon and texture stretching and disruption.

Here's a grab:

You can see the misplaced lines and so on. It really seems to affect trees. It seems to happen totally at random with no real thing to make me think "thats causing it". Sometimes it will happen after 5 mins, sometimes after an hour.

Alt tabbing to the desktop and back seems to remove it for a random amount of time, as does the game having to load a transition screen.

The laptop is an Alienware Area 51 and the card is a gf go 7600 with latest driver.

Many thanks

 

Try forcing Vsync on in your Nvidia control panel settings for Warcraft. Turn triple buffering on as well for good measure. Post back with results.

 

OK, both done. Really didn't seem to make much different, within 1 min of play, I was seeing this:

This is with Vsync (geforce control panel) forced to on, instead of to application. Vsync and triple buff on, in game.

Thanks

 

maybe your drivers man ?

my brothers playing warcraft on a 6100 or something like that and only 484mb ram , abeit on low settings it still runs ok !

love the look of that eagle btw

 

Not drivers, no, very latest version

Reading the wow forums, this happens to others. Blizz always blame it on overheating nvidea cards... hrumph.

 

Those are artifacts as a result of a overheating video card or bad VRAM. One of two solutions would be to underclock the card, the other would be to check the fan for dust.

 

very latest doesnt always mean whats best for your card fella , so try out others

i installed the latest and had issues with battlefield 2 like that

also like above....give the fans and vents a good blow to remove dust,this should be done regular

 

The problems look more like artifacts than tearing to be honest, a tearing would be horizontal and it will just be a segment of the whole screen out of place, shifting to the right or to the left. Are you overclocking your card? Also, get a program like RivaTuner and check your GPU temperature, it could be overheating just you are unaware of it.

 

Agreed. That is definaiely artifacts as of result of overheating video card or bad memory on the card. Should do a periodic cleaning of the videocard cooling device.
