Limit FPS in Editor for all projects

So the same old question and still no answer.

I’m sitting in front of editor and just looking at monitor and my GPU is roaring, my PC is at 870Watt. It is summer and my room temperature is raising every minute! Then suddenly I realize this is a new project and I haven’t set a FPS limit. Setting it to 60 and now GPU is quiet, my PC is at 128Watt (reading from the plug power meter).

how do I limit (ONLY) Editor FPS to 60 without limiting FPS on project (game) itself. This should’ve been a simple setting in Editor Preferences but it is not there.

I already know how to run t.MaxFPS 60 from console (it works for session) or how to set it to 60 in project settings (limits the FPS in the game too).

I have also tried placing t.MaxFPS=60 in every single place suggested in forums and AI etc. It simply doesn’t work. It might have worked with Engine 4.xx versions but it doesn’t work with 5.xx engines anymore.
