I have noticed the performance problem, too.
That's one of the main reason I switched back to XP.
The performance problem can only be prevented if using the "Classic Interface (windows 2000 look)" in Vista.
I noticed the problem in nearly all applications not only in Upp apps. Example: Firefox, IE, ....
It was very visible if I had maximized the window and scrolled the content of the windows with the scrollbar. I'm using a 1600x1200 resolution.
Resizing windows is very sluggish, too.

The main problem seems to be a small (but IMHO very annoying) latency between the action (ex.: scolling a window with the scrollbar) and the visible execution of the action (painting the modified content of the window). It looks like Windows is preparing the windows content in a back buffer - but unfortunately - displaying the new content 2-6 screen updates later.

I used the newest graphics drivers of course.

XP seems to be so much more responsive then Vista. Vista is even more worse than KDE or GNOME. Well, thats my opinion. Don't want to start an os flame war...
