BleepingComputer.com: Doom 3 with Omega Driver

Howdy
Recently I bought Doom 3 and I was able to play it at 1024 by 768 at high res. but I wasn't satisfied with it. The gameplay was pretty smooth. but if I wanted more resolution, it would really lag. I decided to download the Omega drivers, and I immediately saw the difference, the graphics were much smoother and faster. But my joy would end soon...
After I changed the res. and ran the program again, teh screen would flicker, making gameplay impossible. I played UT2004 to see if it happened again, but it didn't. So the problem only happens in Doom 3.
Can anyone help me?

Sweet
I foud out if I turn on the vertical vsync, the flickering stops, and it runs great.
