Windows Vista Ultimate works wallpaper "DreamScene" how much CPU to use

"Ultimate", the top version of Windows Vista, has a bonus feature called "DreamScene" that makes a movie as wallpaper, but it seems that if you are watching from the end, you seem to be using CPU tremendously. According to Microsoft, it is said that it is not that heavy as it uses GPU (Graphics Processing Unit) necessary for displaying 3D graphics for processing, but how much CPU processing will be lighter by experiment It was.

That's why, from now on, installing "DreamScene" will actually run and compare it.
The actual movie of "DreamScene" looks like the following.

So, first of all if you do not have GPUs. During DreamScene playback, I use 30% ~ 50% CPU. Stop it and it will return. The graphics score of the Windows Experience Index is 4.0 and the graphics score of the game is 2.8.


The next time you have GPU loaded. Even during DreamScene playback only 3% to 5% will rise. I am using nVIDIA GeForce 7900 GS (256 MB, PCI - Express connection). The graphics score of the Windows Experience Index is 5.9, and the graphics score of the game is 5.8.


Apparently it seems quite practical if the GPU is a powerful environment.
