dreamscene....

[mcxeb52!]

I have windows vista ultimate's dreamscene update. When using a video desktop background, explorer.exe process seems to increase in terms of CPU usage, I think to almiost 100% sometimes.

Any reason why explorer.exe's CPU usage goes up like that and also the video background pauses intermittently sometimes (like when you're trying to play HD video but your graphics card is the bare minimum needed to play it).

I have a geforce 8500GT with 256mb ddr2 ram, 1gb system ram and AMD64 Athlon processor. Maybe graphics card is not powerful enough or my processor isn't powerful enough to allow smooth video playback for dreamscene?

--------

Dreamscene is a nice feature. If it causes problems, I' can always go back to a still desktop background. However, if I can get dreamscene to work properly, why not use it?
