Windows DreamScene is a utility that allows videos and other optimized animations to be used as desktop wallpapers. It is one of the Windows Ultimate Extras[1]. Prior to its official announcement, DreamScene was rumored to be in creation under the names Motion Desktop and Borealis.[2][1]
Rendered content included with DreamScene (such as an animated realization of the Windows Aurora background) was produced by Stardock Design, while photographic content was provided by the Discovery Channel.[3][4] Third-party video content in MPEG or WMV format may also be used.[5]
One of the purported advantages of DreamScene over previous methods of desktop animation is that it makes use of the GPU for display instead of the CPU, leaving the latter free to perform user tasks.[3] To what extent this is achieved is not specified. Content encoders need to strive for a balance between compression and file size; decompression requires the CPU, but larger files take up more memory and may cause the disk to be accessed more frequently.
Running a video in the background would have a significant effect on the battery life of mobile computers, whether or not it were rendered by the GPU, so DreamScene may display a static background when a computer is running on batteries.[5] The software relies heavily on the Desktop Window Manager (or DWM, part of Windows Aero).
