We can probably fix that a bit. I am using "automatic update" mode where the driver needs to analyze and compare successive screens to see what changed and to decide what update method to use. We can control that by TELLING the driver what mode to use. That would probably save significant kernel processing time. Also, for video games, you can tell it to update a small region (within your known "dirty rectangle"), but for videos like this, there are usually changes all over the screen, preventing that option.
