Erik,

My one concern with lowering the joystick sample rate is that you have
now lowered the rate at which aileron, elevator and rudder input is
sampled.  For some people, the input delay in simulators is a huge
complaint.  Could we perhaps limit the sample rate just for the
buttons, but not for the axes?

For people that are used to flying simulators, 20hz is probably no big
deal, but for people that are used to flying the real thing, this can
cause problems.

I've seen (*many* times) that people have PIO (or driver induced
occilation) problems the first time they step into a sim.  It takes a
while to get the knack of staying ahead of the controls.  We probably
don't think about it, but for someone not used to
flying/driving/shooting sims, it can be really tough.

Thanks,

Curt.
