Okay, here's my problem. I've used a few DeskScapes from here, and the one included with Windows Dreamscene. ALL of the animated wallpapers have caused my CPU to go beserk. It hovers at anywhere from 25-40% all the time, with just Firefox and Windows Sidebar running on my machine.

I thought that Aero was supposed to take advantage of advanced graphics cards instead of CPU, and pushing all the energy needed to create cool glassy effects onto the GPU instead. Last time I checked, I needed Aero to run DreamScene, and DreamScene to run DeskScapes. Whats up???

Here's my system:

Windows Vista Ultimate
AMD Athlon 64 X2 3800+ (2.0GHz)
1GB PC4200 DDR2 RAM
ATI Radeon X1300Pro (256MB)
