Oh, I was thinking about the water physics itself (including water effects). As you can see in DWP1 water physics was creating the garbage, while in DWP2 there is no garbage on the physics itself, only the boat. You are also comparing performance of different scripts in images 1 and 2. I will check what is causing this since there is no reason for ship controller to generate garbage either. Ship controller remained mostly the same from DWP1 as it was a physics update - sorry, did not even realize we are talking about the ship controller. Fix incoming.
