Tempted to flash it, but I don't know because 2.5 runs very smooth for me.
Been running for about 4 hours now. Haven't had a single problem, redraw, or FC. I wiped EVERYTHING before coming to 3.0 and put the exact same kernel on that i was using on 2.5.
Had a couple market hiccups but that's about it. Just make sure you go through the UD Setting Performance tap and do the correct tweaking. I did and haven't had a single redraw yet. I'm running ADW EX.
