Display settings are here! Or, at least, UE engine graphics settings. I know its been asked for and I needed to make progress on that. Users can use the Display Options now for not only Fullscreen/Windowed, but the other usual UE5 scaling settings, such as Shadow Quality, Anti Aliasing, Post Processing, Effects, View Distance, Illumination, Textures, and Reflections.
Fair Warning, you can set Illumination below High, but doing so will essentially disable Lumen and lighting will be mostly dark.
More to come. I think I will have to pull off something that looks a little different for the Resolution menu, and I may have to figure out if I can get aspect ratio changes in as well. Happy wandering!
