If you're using the L4 in DirectInput mode then this card uses an
entirely
different method of reading the joystick than how the normal gameport
works.
The card itself does all the capacitor reading, at a very high rate, and
it
does all kinds of fancy smoothing to the results to produce a very
stable
joystick position value. Then when software such as GPL wants to read
the
joystick position, the card transfers that info instantly. Thus freeing
up
the CPU from all that time just sitting around doing nothing while
waiting
for the joystick capacitors. There is thus no problem with other
devices'
interrupts. In fact, I don't even recall seeing the option for polling
with
interrupts in the Joystick control panel applet when I had my L4
installed.
But if you use the generic joystick setting in GPL then the L4
automatically
switches back to behaving like a standard joystick port.
I don't know what might be causing your jumpy online performance, but
the
L4 shouldn't be the problem. You've changed enough other items between
system upgrades that almost anything else could be the cause! :)
