high CPU load in Fullscreen mode (1 Viewer)

[swepisode]

Hello,

can someone help me to understand why Mediaportal in windowed Mode use only 15-20% CPU usage and in Fullscreen Mode near 100%
I think it can´t be a graphic card problem (driver or the non dx9 compliance).

the graphiccard is a intel 845GL with shared memory and is not dx9 compliant.
it works well in windowed mode

thank you so far[/b]

Whys that? Id be looking at that video card, its probably not DX8/9 compliant or it has too little video memory.
