We are not working with the same configuration, but a similar one,
with our own tracker access (serial connected Flock of Birds) and
experienced exactly the same, just with Performer 2.2, and we tested
both Elsa Gladiac 920 and ASUS V8200.

In contrast to your experience, we don't get good performance even
without using a tracker (mouse steering).

Something we found is extremely many system calls to getpid() and
gettimeofday().
