In Quake 3, on maps where snow is present, thin, vertical white lines are present almost as if they are deliberate. Browsing the internet and watching flash demos etc produces no problem, it seems to be only with things the graphics card has to primarily generate.
When installing the latest drivers, the card slows down to a crawl and it takes 10 seconds for it to draw the start menu, AND the problem is still there!
If anyone could help I would be much apprectiated as I have tried changing settings, resetting them, installing and re-installing new drivers and much more.
Is it possibly a duff card?
