Whoa!! I guess I never truly realized it before, but damn: I really am quite spoiled. The Majestouch Tactile Click NKRO is my first mechanical keyboard!
Anyway, thank you for that good comparison!
Were (or are) you using the USB to PS/2 adapter? I mean, this has nothing to do with the switch type; it is related to key rollover.
it only happens when u hold 2 keys at the sametime more then 1~2 sec in the GAME
