I am working on a (until now) simple patch that is loading a spread of filetextures to be able to scratch through them as high performance video playback with variable speed, direction …
When the renderer is in windowed mode the system load in shown in the task manager is close to zero (as expected), but if i switch to fullscreen, system load increases a lot.
Size of the renderer was very similar in windowed and fullscreen mode.
Why does the system load changes that much when switching to fullscreen ?
I can not see a logical reason for this behaviour !?
