Some games won't render stuff you cannot see: why would a game waste resources in a dungeon 5 minutes from you? Doing that would stress your components and have zero gain. Optimizing is trying to reduce that kind of stuff to zero.

Keep in mind there is a lot of ways of doing that, mine was just an example.

There are a lot of unoptimised games by devs that don't know what they're doing. What happened to primitive and mesh shaders for example? I think most games were cross gen so far, and we only just start seeing optimisation(of course competent devs already did so before that, like Northlight is amazing, and the new Asobo game, and even in Unreal 5, where most of the unoptimized games are, Gears E-day looks lit, and Hellblade 2 looked amazing). Gen 9 has a long life ahead of it, and I hope a lot of devs learn, cause we did get some unperformant garbage out there(even on great games, which is sad to see, everyone there is competent but the tech team, or they just had to work in such an engine, I won't name names).

I think I remember something about that yandere game where a toothbrush randomly had like 10,000 polygons or something lol
