Performance of the different Vista themes

[Spooky]

Possibly the differences lie here:

where it says "When desktop composition is enabled, individual windows no longer draw directly to the screen or primary display device as they did in previous versions of Windows. Instead, their drawing is redirected to off-screen surfaces in video memory, which are then rendered into a desktop image and presented on the display."

Ok, then the circle is round. I already noted, that it can only work when this feature is enabled in my first post. You provided the explanation for this, thanks.

Imagine what the performance of hardware-rendered Windows Classic would be like...

It is already hardware rendered, just not by the hardware you want it to be rendered with ;-). I think the difference would be unnoticed. Aero interface would be a totally different story.
