So, While trying to improve a script, I came across something I learned a very long time ago, but obviously Forgot.
Anytime Your Perform a Key() Command in EUO, there is a wait timer included in the Command, something around 250 ms on my computer.
In My Script, I Will cancel a target Cursor by Doing Key ESC.
My new Method is to just
set #ltargetid N/A
Event macro 22 0
Which only takes about 20 ms. HUGE DIFFERENCE. It does give me a Target cannot be seen message though, which I guess might cause crashing. I'll post more as I play.
