Does disabling Aero improve performance?

It doesn't increase the computer's performance noticably. In other words, it does in theory but you won't fee they awesome millisecond difference. I've a 2 year old PC with a Pentium DC 1.6 processor that's always running at 800Mhz and it only has integrated graphics. I don't see any difference in smoothness, response whatsoever between enabling Aero with all the visual effect and disabling all of them. At the most, when I disable the visual effect, the animations don't play, so yea, opening folder, minimizing and stuff doesn't get that quarter of a second animation.

My Aero score is 4.9. Even im suprised.

Aero or Classic, My computer seems the same.
