Got the omega drivers for CAT 3.10 but they didn't work, couldn't get SMARTGART to hold a setting so it was at 0x AGP. Dunno if that was just a bug because I was still able to play the usual games albeit at a lower framerate than the omegas based on CAT 3.9.
So I ditched the omega 3.10s and went back to 3.9 (2.496c). I've heard that the previous versions seem to work better for some people, I started using from 3.9 so maybe I'll try the 3.7s, see if there's an improvement in framerates.
