We all do. But… that’s not the same.
You can’t always do that.
And you should not unless you need to for other reasons- open world, daytime cycle, etc.
For instance, 2m loading on a mobile app to get an always seamless level gameplay is not a bad trade off… even on a switch it could really be worth the time waiting to get a realistic light effect.
Remember the skyrim days where we probably all burned at least one gfx with mods? I know I did… looked like a different game in the end though. Was almost enjoyable despite the lackluster story…
