CPU jumps up past 50% on the System Monitor graph with both g-s-d and gnome-display-properties (top claims +60% CPU usage for Xorg). I used glxgears below. I'm not sure how I would test with xrandr. xrandr --auto just takes a second and there's no spike on the cpu history. By running xrandr repeatedly maybe there's a slight increase in activity, but nothing over 50% CPU.
