Computer keyboard lag?

[Av23]

Dude! You play LF2 and press the key very hard on laptop?!That will destroyer the keyboard. If you want to play it on a laptop, use a joystick, game-controller, another keyboard that's connected.
Firstly,
I not sure what's the key your movements are. If it's shift, it will become a sticky key.
Secondly,
If your keyboard is bad, buy a new one if you wish. But everytime I play, it works fine.
The main problem MAYBE is that:
You're too angry because:
The move won't work, but you're pressing the wrong button.
You press too hard.
Sometimes you didn't look at the mana.
The moves always include "D", so make sure you're not going to attack when you're defending, that won't work.(Except davis's dragon punch, deep's strike or woody's flip kick)

Edit:
@Kevin,
Dude, I play hero fighter with two of my friends on one keyboard, but it works fine. If you're having problem about pressing, press F1 or tell your friend to quickly do something to help you.

maybe it is because you got a good keyboard?

what type of keyboard do you have?
