This is not a driver bug, and we've already spoken to Mozilla about it.
While my 7950 was sent for replacement, I installed my old GTX460.
The clocks on Firefox were almost 90+% in idle mode, just 50Mhz ( drivers 310.33 ). The GPU loading was as high as 50% without waking the 2D or even 3D clocks, like my 7950. And don't forget the 7950 has 300Mhz idle clocks, not just 50Mhz. I'm not talking about videos. Simple loading/rendering websites. On GTX460 not even the scrolling could wake higher clocks -which unarguably is a "heavy" process.
I'm tracking Fx's GPU behavior for long time. This clocks-issue probably has nothing to do with the reason Mozilla is blocking 12.8 drivers and ownards ( Windows 8 - On Win7 only 12.8 is being blocked ). I think they said something about Memory corruptions and 2D performance -you should know better.
Do you think we're going to get HWA on Firefox on Windows 8 within 2012?
P.S. To be honest, I don't trust Fx's HWA as much as Internet Explorer's -thus, as simple user I can't tell whose fault is thisEdited by Deo Domuique - 11/9/12 at 6:54am
