I‘ve noticed that as well. I much prefer say Tomb Raider 2 with its clear edges and flat surfaces to the modern ones with all the foliage and clutter and lighting effects. But I put that down to getting old.
it's not just the visual noise, it's also the inconsistent behavior introduced by those details.
Yes everything being flat boxes was boring looking but I knew exactly what would happen when I tried to shoot through it or bounce a grenade off of it.
Now it's not obvious if that stack of sandbags is actually a single surface and my grenade will bounce off of a gap or if it will go through it. Or if that random bucket I'm shooting at is synced on the server and real or is a local prop.
