OK this is pretty sweet. With T3 the jitter never exceeds 7% on an idle system. As soon as I start moving the mouse this goes to 7 or 8%. I cannot get it to go higher than 10%. Moving windows around has no effect, the highest jitter happens when I type or move the mouse really fast IOW it corresponds to the interrupt rate.
This is a pretty good baseline for what an xrun-free system would look like. Now to test the latest version...
