Hello :)

Since i've installed windows 7, my graphic card is always at full activity when I run a not so 3d-intensive game and when I open it 2 times, it goes really slow and choppy.

The thing is, on windows xp, i could open 4 or 5 times the game without any lag :/

I suspect the windows 7 driver is the cause of my problem

When I check my gc with gpu-z, i see the catalyst drivers being used but when I run dxdiag, here's what i see

Is there some kind of conflict between ati drivers and HDDM 1.1?

I've tried HDDM 1.1, catalyst 9.8 and 9.9 but they all give me the same problem.

I'm starting to get really desperate and considering buying windows vista. Could somebody please help me? :(
