PS5 is not exactly 3… it is Epic that have some confusion if it is 3 or 4 because the demo shows different results based how you compiled or used the Editor.
By documentation Epic is 4.
Alex said that:
“according to UE documentation setting 3 is high, 4 is epic, 5 is cinematic ^^ - and if you want to find the exact settings console uses from a visual standpoint I recommend doing the comps.”
But that lead to some inconsistencies by people using the compiler Demo.
“Hmm, so you are indeed infected with the 3=high virus too, I see
Do not worry, I will cure you! :-D
Is that UE documentation up to date? If you run it at Epic scalability settings in the editor, it looks and performs exactly the same as config file 3 would (and compiled version also defaults to 3 like it does in the editor to Epic). If you set it to Cinematic, it will perform much worse, both in the editor at Cinematic and in the compiled version running at config file 4.
Also if Epic is 4, then 2 must be medium, which turns Lumen GI completely off (according to Epic's documentations as well) However, in the sample Lumen GI turns off at 1 and not at 2.
I am also pretty sure there is a performance and visual quality difference between 1 and 0, but I still have to test that!”
