Optim: TickMode 1 - allow triggers to sleep if they don't move on specific axis and internal entities also don't move on specific axis - took out internals of BaseEntity.HasMovedInLS to BaseEntity.ComparePos(Vec3 from, to) - Player Boats now set interest in XZ when alive, XYZ when sinking - Buildfix for SERVER only code (whoops) This brings 100 boat test to 0.25ms (down from 1.6ms, -85%), or down from 3.1ms, -92% from TickMode 0 Tests: built a boat, set tickmode 1, jumped on and off - got unparented. turned on the engine, jumped off - got unparented once in the water. noclipped above with engine on - got unparented after a delay. Spawned 100 boats.
