Well, I don't know what to tell ya there. My notebook, P$ HT 3.06, 1 Gig Ram, INVidia GeForce FX Go 5600, Aero Graphics and Flip 3D were not compatible. But reading the requirements, I expected it. I had enough ram, but not enough video card for it.
Now, if you are running a newer video card, with at lease 128Mb dedicated ram, Aero shouldn't be an issue. It amy be your video settings or maybe your load giving you the issues.
I will, however say that Vista, even minus the Aero Graphics and Flip 3D seemed to work quite well. I am still running it on my notebook, despite the lack of.
And I am still enjoying the computer.
