How do you turn on vsync for the editor?

How do you turn on vsync for the editor/level. My monitor is at 60 htz but the level preview is clamming 118 fps. How can I lock this to 60 fps or even 30 fps? Right now my vid card is pumping out a lot of heat when it doesn’t need to. Yes, at some point I will need/want to know what max FPS is but for 99% of the time I need my system to run cool. I would love it if I could cap the frame rate to 30 fps until I need a full speed test. Is there any way to do this?

Press the tilde key and type “t.MaxFPS 30”
Replace 30 with 60 or whatever frame rate you want it locked to.

You can make the change persistent by adding “t.MaxFPS=30” under the [Startup] section of the console variables ini file (config/ConsoleVariables.ini).

Thank you, this is exactly what I needed!

Big thanks for answering this question

I put t.MaxFPS=30 into the config/ConsoleVariables.ini of the Engine (5,1) and then I went into the editor and input stat fps into the console, and the fps is still around 80.

Am I doing something wrong, or has the way to do this changed?

this console command works for me on ue 5.1, it limits the editor fps but I believe vsync is still off as there is still bad screen tearing

Try r.VSyncEditor = 1 to prevent the tearing.


So just in case anyone else has been wondering, I’ve found other sources where people are saying you can add this to the DefaultEngine.ini file under [/Script/Engine.RendererSettings] but that wasn’t working for me. Instead I had to add r.VSyncEditor=1 to the ConsoleVariables.ini file. (for me it was here: C:\Program Files\Epic Games\UE_5.3\Engine\Config)
