Most of the major joystick companies made a version of speed-compensating gameport card at one time or another. Gravis, Thrustmaster, Suncom, CH...pretty much everybody.

I'd like to hear some VOGON'ers thoughts on the usefulness of speed-compensating gameport cards, like the CH GameCard III, etc.

At what speed/class of PC are they necessary or useful? A 386/SX25? A 386/DX33? Or not until you get to the 486 machines running at 66MHz, 100MHz, or higher?

I'm speaking about their use when you would otherwise be stuck with your non-speed-compensating onboard gameport like is found on the early Sound Blasters up to and including the SB16's (did the AWE32's or AWE64's also have the same NON-speed-compensating gameports?).

So when, or under what configurations of machines, did they become necessary or at least a useful improvement?
