Hi i'v a problem that I don't really have any clue what it is caused by

I use a bind to both zoom and select rail: "weapon 7;wait 10;+zoom"
sometimes, not everytime, just randomly
if I fire a shot, it lags and fires after a while, or just delay when -zoom
I'v no idea what the problem is...
I'v this issues since I tried cypher cfg

that's my autoexec: http://pastebin.com/L44m2GMw

do you know what the problem may be?
