Keyboard spits out 2 letters when pressing X

[purplebro11]

so i play a game where i have to press letters cxz real fast to do a combo. when i press cxz real fast it types the letters "cxxz" my x always doubles when i press it really quick, but its wierd, if i type x right now, it does not double? its only when i hold it down for a short time and press another letter. cxxz zxxc. I need this for a very important combo, someone please help.

Try changing the key repeat rate in the keyboard/mouse options. Aside from that, use an external keyboard, preferably one made for gaming.
