How to add r.FullScreenMode 0 in standalone ?

So here is the thing:

As soon as i have my game in fullscreen— fullscreenmode 0 it all runs very very smooth.

But… in fullscreenmode 1 or 2 its terrible.

I created a defaultgameusersettings.ini file and my packaged build is in fullscreen from default now but… my standalone in the editor is not, and if i add -fullscreen in the additional launch parameters it DOES make it fullscreen but it DOESNT set it to fullscreenmode 0 from default…

It even doesnt if i add it in the level blueprint so my question… how do i add it to standalone?

Bump please help

Really nobody?

Bump again…

Bump please help someone!!

Still no answer sadly…

PLEASE someone give me an answer!

Did you find a fix for this problem because its happening in 4.19 unfortunately.

you could have a console command run from the first level that opens with your game, or even from your game instance, that executes console command: r.FullScreenMode 0

so on the level BP , add the execute console command node and type in r.FullScreenMode 0
