Yes, but I did latency testing for Robert for several months, now.

I am, too. But more for 3D visualization/simulation (with audio).

Not for me. Even when lock-brake is applied.

Q3A is _NOT_ changed in any case. Even some smoother system "feeling" with
Q3A and UT 436 running in parallel on an UP 1 GHz Athlon II, 640 MB. Have you

What problems? Are they TUX specific?

Some latency numbers coming soon.
