What can i disable in order to get more FPS in packaged game?

The game i am making is not graphic intensive and i want to disable almost everything that i don’t need. The engine scaleability settings did not help much. I’ve found something in the Project Settings at the Rendering section but i don’t know what to uncheck etc. If i kill all the lights i get more FPS but i obviously don’t want that. I’ve also heard that Unreal has enabled post processing effects etc in all cameras and the game by default. How can I disable all of these?
I need the minimum available settings.

Thanks in advance.

Setup a graphics options interface and use the scalability commands: Scalability Reference | Unreal Engine Documentation

Certain things give far more performance than others, and you’ll need to tweak to get the look & fps you want. Instead of turning off lights, you could try turning off shadows or just reducing their quality.

Also be sure to check out optimization viewmodes to see if you can optimize anything.
