Recently, I watched some speedruns and noticed that during blind travel, when they throw an eye, the resolution gets stretched. I'm just wondering how I can do that

Ex :

It is called eyezoommacro and it doesn’t stretch the res (it looks like that on the recording) it zooms in on the eye. Here is a tutorial setting it up You need auto hotkey. Also if you don’t use fullscreen then there is an alternative in the descr of the vid.

Thank you
