It's surreal how bad UE has gotten.
To me it has been bad since unreal engine 4 went free, unreal engine is usually used by
hacks developers that want the "easy way out" when it comes to graphics. Unreal engine comes with a bunch of ready made tools / solutions so all you have to to do is just paste models, maps, textures and you good to go (hence why these games usually have horrid optimization)
And maybe its biased but almost all unreal engine games look the damn same to me, its like people using unreal engine games hate
art styles 
Oh and also ABUSING the typical unreal engine effects (ambient occlusion, SSR, bloom, LENS FLARES (its cinematic!!1!1!!1), motion blur, etc.
I know unity gets a lot of shit as well specially with the assets flips, but I take unity over unreal engine any day, its more mod friendly too.
But like, the fault is not entirely on unreal engine itself (even tho apparently it lacks proper documentation on certain things like lumen and nanite), the fault is also on developers refusing to optimize their stupid games in the first place. After all the engine can the best thing ever created by man but if the
hack developer doesn't do the proper research / optimize the code and assets then a lot of pc's are just going to go into a coma when trying to run said game.
And I don't see much in the way of "excuses" here because these indie devs don't have shareholders or a publisher breathing down their neck, there's no rush or reason to release things unfinished / badly optimized,
Unreal engine 3 had its problems (hello piss filter) but to me it was and still is the best "unreal engine", outdated, sure, but graphics mean little to me anyways. at least it ran well.... even if it had its own share of problems (texture streaming).
unreal engine should've stayed a paid engine, being free attracted way too many """""developers""""", just unity situation all over again.
