Huge FPS drop in Editor after opening Blueprint window

[Roshondas]

Hey, there’s a problem a lot of people have been talking about for years. It will be nice if someone at Epic tries to fix this problem.

There is a big FPS drop with addtional windows open - especially with blueprint window, the more nodes the more the drop FPS drop. Blank blueprint opened as window drops on the Blank scene from 300fps to 60 on the RTX 3060TI

Hello!
Do you have any application that monitors your fps or adds an overlay?
In my case, I had RivaTuner which caused the fps drop, immediately after closing it everything was fixed.

Thank you very much for this answer. I wasted hours on reading different solutions on forum and nothing worked, but right after I turned off Riva Tuner my FPS now stable even if I open new windows or see windows pop-up in editor.
P.S. Doesn’t matter if currently riva tuner overlay active or not, because Riva Tuner itself should be shut down.
