Game Lagging - How to stop it?

So here’s my standalone game, and as you can see there are not that much complex or highpoly objects. When I start it in Blender there is lagging when I spawn my player. How to stop it, and tell me if it’s lagging to you.

Ok… I can only see that little bears? move slowly but the camera rotates quick and flow and when i have added all turrets all work fine.

But it is imposible make a better valoration without see the blend… or if you dont want to share it, a video showing the issues you are talking about would be great.

Ok I’m going to send you my .blend, but I trust you, respect that.

Try to dissolve some vertices that are flat. Like on platforms and flat surfaces and that should do the trick :slight_smile:
