 ## Box2D (2.4.1)
 
-- performance a little bit worse than godot.
+Pros:
+
 - best stackability.
 - best joint stability.
 
+Cons:
+
+- performance a little bit worse than godot.
+- missing simd and cross platform determinism.

 Notes:
 
 - CharacterBody2D.move_and_slide implementation is very jittery (this does not reflect on the libray but on me, the one who wrote the wrapper that integrates Box2D).

 - in reality after a certain amount of objects, it starts to jitter a lot, making it completely unusable (eg. objects pass through things and other bad things).
 - stability last place.
 - stackability last place.
