 # Is this allowed in speedruns?
 
-Not yet.

-# Why is the sensitivity suddenly so low?
-
-If your mouse has a high polling rate, the mouse hook will, for some reason, slow the ingame sensitivity. I don't know why. Either reduce the mouse polling rate, or bind the macro to a keyboard key instead.
+Yes.
