Apparently, you can now move static 3D colliders in Unity 5 without performance penalties (at least in terms of framerate). Unfortunately, the Profiler still spams the following warning if I do so: So, is that indication that the feature is non-existent or is something messed up? Or should I just ignore it and move on? I didn't notice any serious performance issues caused by physics anyway, so I guess it's working as intended. I just wonder if I should still keep getting that message. Maybe that's just a remnant from older versions of Unity which should be removed soon. Or maybe I missed something in the docs.
