Or i dont get what you mean guys by using simple physics (its on settings right ? )
That was the 'simple physics' I was referring to. From what I could tell from the hxScout analysis, it looked like overlap detection lag was the fault of a small number of culprits--so if you can identify those actors it may be a simple fix.
Unfortunately, I don't have any good suggestions on where to look. Like rob1221, I'd have to spend hours studying your project to figure out how it's pieced together.
From your video, I noticed lag starting at 2:40, when the gold-colored actor comes into the scene. Does removing its collision boxes entirely have any effect on lag? If so, then I think you've found a direction to go deeper toward--the collision boxes of larger actors.
