Well, my keyboard stops at around 10 (or maybe I ran out of fingers!) so it's not that bad. But, there are certain keys that "lock out" others no matter what. Very frustrating when you're playing an FPS which requires you to press many keys at once while controlling your character..
I have a little test program I can send you that interactively tells you how many keys are pressed. I was able to press keys 1 thru 0 giving me 10 keys at once.. This way you can spot which keys block others out (if any).
Oh and it's a realmode dos program that hooks the keyboard interrupt, so it's more "raw" than DirectInput.
