Windows 8 Consumer Preview problems

Am I the only one that experiences issues with frame rate with the Consumer Preview? I notice that the clock speeds on my 580M's only go as far as 2D desktop speeds when gaming.

I do have missing drivers which windows can't install or find. I can't put drivermax on to get them either. I will add to this when I have a look to see which drivers are missing.

BTW, I have the latest win8 drivers (296.17).

At least I put it on a partition otherwise I wouldn't be able to play all my games :)
