take A LOT of time to trigger, like 1-3 seconds, to the point of stop being useful because I have to be waiting for the windows to be moved and resized.
An ancient software like WinSize2 ( https://winsize2.sourceforge.net/en/index.html ) can move and resize a window like 10 times faster...
We're limited to whenever that event is sent, there isn't much we can do there
But how is WinSize2, which is 12 years old software done with AutoHotkey by 1 guy able to process the windows immediately instead of the 1-3 seconds that DisplayFusion takes? there's clearly something that can be done...
