Editor Menus and UI Effects in UE 5.3.2 extremely delayed

I finally found the solution myself. Here is the link to another (more responsive) forum I was in: Incredible UI lag in UE5.3.2 - #13 by Ayhan_Sakarya - Ask - GameDev.tv

TLDR: I uninstalled the software called “RivaTuner Statistics Server” and the UE editor suddenly worked like a charm.
