But Left4Dead2 just running in circles in the saferoom goes from fully playable/liquid smooth at minimum brightness, and then at full brightness it drops down into unplayable territory. turning the brightness down again causes the game to run smooth again.

I've gotta say, for almost certain, that there is also a bios or software update required.

But the good news is, the new brick runs very cool, in fact before i had to game at minimum brightness to get good fps, and now i can run it at halfway which is whats suggested for the best RGB colors. So the 130watt is helping somewhere (and running very cool while doing it)

Looking forward to that bios update. Even if it takes like 5% off the max performance possibility of this laptop I'll be happy just to have reliable and consistant performance. I can't imagine that we'd lose any power though, these things dont get warm at all considering my old Asus was 80c out of hte box. lol
One last update. The latest catalyst drivers (9.11?) modded into the system helped out quite a bit with the stuttering graphics... its still there but its better. Interesting.

Battery vs. AC adapter performance is identical for me now at all brightness levels. We're beyond the power draw issue at this point, or at least thats what it feels like to me in my case.
