Jerky might just be dropping frames too! Also, you should make sure
that you're either running as root or have sufficient access to
/dev/rtc to get high resolution timing. Otherwise the high
framerate isn't possible.
Running as root didn't seem to make any difference, no frame drops
with -s except for one at startup or when I drag windows around. (rtc
module is loaded ok)
The problem with dragging windows around is very noticeable for me. I also see dropped frames only by changing window focus, but then again, I have only a P3750.
I wonder if a deeper look into how the window manager handles (read: if it compresses) StructureNotify, Enter/LeaveNotify & other events would reveal some seriously broken WMs. Some simple experiments showed that sawfish was much better than metacity in this respect.
