Depends on what the limiting factor is. If it's the physics code, dividing the world into several chunks might help. So you are only checking the collision of tees and other entities which are inside the same chunk. Might aswell be the netcode, snap creation, 64 <-> 128 mapping code or whatever but i rather suspect the physics code

pred time seems better now but the pred margin graph has frequent spikes
