When you trigger overload several times the game slows down once the overload cooldown ends after a certain point. Testing at around 8 overloads or so the game will micro stutter for a moment once the overload cooldown ends. After doing about 20 of them the game would freeze for over 2 seconds and I suspect it can keep going up.

DId you monitor the mem usage?
