How to optimize the speed of a script as much as possible.

SetBatchLines, -1 Causes my games to completely freeze to 0 fps until the key is released.

as mentioned by Animan8000 and by point #5 of the thread, you're pressing buttons too fast and your game can't handle it, you need to slow down

5. The default SetBatchLines value makes your script sleep around 10-15.6 milliseconds every line. Make it -1 to not sleep (but remember to include at least one Sleep in your loops to avoid high CPU waste!).

quick solution, just add this line inside of your "freezing loop":
DllCall("Sleep","UInt",1)

To be honest this kind of thread is less needed for AHK v2 since the 2 most important lines SetBatchLines and SendMode (among others) now use better defaults.

But still, here it is viewtopic.php?p=559263
