1 Looks great, but I was not playing the game. Just flying around
2 Not much. Crouching would be the main one
3 Crouching helps there, but there is a bug with them swiping as they walk
4 Hard to compare since there are other general optimizations that make up for it
5 May be better since chunk mesh/collider creation is faster
6 I was checking that optimization/cleanup to biome decoration code did not have errors
7 Seems fine to me
8 Should be the same
9 Same?
10 Don't think so
11 Probably tweaks to some, but a lot of different assets have LODs with separate settings
12 It should be used at some point
