I am new to UE4 and I was working with Unity daily from version 2.5, that’s 12 years ago.
The new version of Unity are getting so slow and unusable even on a top setup, I don’t know what they are doing in their editor but that is become impossible to use at this point.
I have switched to UE4 mainly for this reason, and I will not go back.
I have made a simple memory test, loading Photoshop CS 2017, Discord APP, Unity with an empty project and UE4 with an empty project too.
