I have this problem too, on a Zepto A14 laptop, 9600M GT.
The issues are similar that other posts:
- Performance Level is always 0 or 1, never goes up to 2 or 3.
- Black VTs (this is not really a huge problem)
I didn't try any 3D stuff before, so I discovered this today. This is happening with the 180.18 drivers I'm using currently and a vanilla 2.6.28 kernel.
The 185.xx driver seems to have a lot of updates those days, so I would be pleased to see this issue fixed
Do anybody knows if the 173.xx driver is affected by this bug? It would maybe be the safer way to play games, until a fixed 185.xx driver comes out.
