95% CPU load when running MP under VirtualPC 2007 (1 Viewer)

[elCutty]

Hi,

does anybody know what causes MP to use close to 100% CPU load when it is just idle waiting with the main screen?

It seems that MP is running in polling mode maybe because some resources are missing in the MS Virtual PC.

Thanks

I would think its because there is no GPU acceleration when using Virtual PC so the CPU has to do everything.

But in this case it should be zero load, when the screen has been build up.

The 95% CPU load happens in MP idle Mode.

Here an example of the Load. Animation is disabled.

Hi,

MP renders its GUI with DirectX like a game. Virtual PC does not support hardware accelerated DirectX (GPU). Everything has do be done via the CPU. Run a 3D game in Virtual PC and you will get the same results.

Still can't believe that this is the reason. When the GUI ist build up and animation is disabled there should not be any CPU load. You can even run PowerDVD playing HDV clips on that virtual PC. Not very smooth but it is running using directX filters.

Believe or not, but MP renders the screen like DX games. So that means the screen is rendered for example 50 times in a second (depends on the user setting).

for example 50 times in a second (depends on the user setting).

Where can I change this setting?

Inside MP : Settings -> Screen Calibration-> Scrolling Speed -> Maximum FPS
