I recently put in a new motherboard (A7N8X) and new power supply (Antec SmartPower 2.0 500w). I installed ATI's latest drivers (7.4) and noticed a lot of artifacts. It shows the most when there's a solid background color like black or blue. When I uinstall the drivers and just use the default windows drivers (i guess that's what they are?), I don't see the artifacts anymore but then scrolling and moving around doesn't go smoothly at all. I tried using the Omega drivers (3.8.330), same thing happens. Then I decided to play around with some settings and think I found what's causing it. If I have SmartGart's PCI Read option ON, I get artifacts and smooth scrolling. If I turn it off, the artifacts go away but everything is laggy. Is there anything I can do about that? I was thinking maybe there's some setting on my motherboard that, with the PCI Read on, causes an issue?
