Gang Beasts Stress Tests (Unity 4 vs Unity 5)

A stress test of 40 AI actors fighting in a 5m x 5m NavMesh grid comparing the physics of Unity 4 and Unity 5.

Performance between the two Unity versions is pretty substantial and additional gains can be made by adjusting the actors code to better utilise the updated physics engine. For reference this is running on a 3.4 GHz Int
