Misc performance improvements. Let me know if any issues come up, but from our playtesting the game feels exactly the same, just runs better on lower end spec computers.
Changelist:
- Moved enemy manager from updating enemies at a fixed rate to instead LOD is based on distance from player, so enemies far away from player only tick a couple times a second instead of every other frame like nearby enemies.
- Implemented a bone disabling system for offscreen enemies to reduce physics step time.
