Hi everyone! I am developing a RTS game, where the player can spawn units. Sometimes these units will be overlapping each other (when they are together in a trench/defensive position) - its a 2D game seen from the side that is the reason they are overlapping. When they attack (exit the defensive position) a big lag spike occurs since so many 2D Box Colliders are overlapping each other - i know this because the biggest peformance costs are the Physics2D.FindNewContacts (60 %) according to the profiler All the box colliders are Triggers since i am not actually using the Physics system to detect actual collision but using it to see when a Unit triggers with a explosion or with a trench etc. I have read the following forum post: https://forum.unity.com/threads/profiler-physics2d-findnewcontacts.611584/ Thanks for the help!
