yes, as well as actual pd results. it seems i was using a messed up
custom latencytest, and when i found the proper one (i have many on my
system and it's been 2 years since using them) i got the best results i've
ever seen (1.1ms max for all tests at 0% cpu, 1.2ms at 80%).

so, it looks like the problem must be with pd. i'm going to try some
older versions now.

11, and nothing on 8 or 9 (though my eth, usb [unused], agp card, and
onboard sound [unused] are all on 11 as well).
