Yes No 3.5.1 enabled at all. It's just a minor version jump from the WU one. It's on the AMD site listed as win8 pre-beta (dated 11/25). No CCC though.
I installed these drivers from ATI and have seen that my GPU clocks now are always in 2D mode, even when playing games. I confirmed this by running the Ati Stress test and clocks never change. I downgraded to the 8.88.5.3 preview drivers and all is back to normal. Clocks fluctuate depending on what im doing, gaming or just watching videos and clocks go into Power saver and back to 3D when needed. Im running Win8 (32Bit) and i dont know if its the same for 64Bit.
