I did some more testing, and determined that the problem is my Gravis
GamePad Pros plugged into the Audigy's game port. If I have them in
the special "GRiP" mode (even if only 1 is attached), my CPU
utilization is terrible. If I unplug them, or use 1 in "4 button"
mode, or 2 in "2-button" mode, my test results are normal. I did not
have this problem with my old Diamond MX-300 (Aureal) sound card's
game port.

I tried using the Gravis Xperience 4.5 software, rather than using the
default XP drivers, but this didn't help. I also tried turning on the
(poor quality) on-board sound just to use its game port while trying
to disable the sound portion. I'm not sure if set this up entirely
correctly, but I was able to get sound to go through the Audigy while
the pads were functional in the on-board game port. I still got bad
readings, though.

I could try asking both companies' support departments, but I have a
feeling that they'd just point their fingers at the other company.
