Calm down

There arent drivers suitable for every single graphic card; one driver may be perfect with your gfx, but can suck with mine. Newest nVidia gfx drivers are made with gf 8 series and vista in mind; i ve found them not good for my old gf6600gt, but they can be fine with yours...
What im 100% sure about them is that they acted wierd (ctds) when aa and af were enabled in control panel and that sh3 was looking very ugly and very aliased.
