Need help on AutoHotKey macro problem

I stop playing RO for few month, after i playback it, and i reinstall new version of AHK.
Problem is... AHK cannot work well in RO game. Sometime it will have slow spamming and have some delay, but it will be fine after I close and reopen my RO.

But I tested on notepad or Work, and it work well and didn't have any delay, just problem on RO game. So i think that it maybe the problem of game.

Any1 also have this kind of problem, any1 have any way to fix that?

i use this for DS try it but meaby server have anti ahk i know 3 servers cant use ahk

$Q::
Loop
{
if not GetKeyState("Q", "P")
break
Send {Q}
Click
}
return

Is that mean because the GameGuard cause the AHK become slower??
