Problem - you're lagging and dont see what happen on the screen ?
Solution - stop pushing any of the button and the game will refresh instantantly (works for me)

Problem - you don't know if you hit the opponent and where he is !
Solution - think like a blind man, use your ear ! the sound isn't affected by lag (in my case anyway)

Problem - you arent able to make the super out !
Solution - try hitting the punches button one after an other the first move will cancel to the super (works for me)

Problem - you cannot make any special moves
solution - Dont be to quick on the keyboard and relax when playing

***Hope it will help people get better***
