A framebuffer device is usually slower than a native driver under X.
My Freerunner's UI performance definitely felt a bit faster after moving
to the native driver.
I also noticed this in my SmartQ7 after moving from the framebuffer to a
The slowness of the graphics is better explained by the brain deadness
of the hardware.
