Massive RAM usage on mostly empty level

Hello, i want to give you feedback.

After a month of clearing depoendencys, i have reduced the connections massivly.

But i still have up to 10 gb of memory usage on the engine.

The Plugings dont make a huge difference if i deactivate them:

I also have a few question:

  1. if i added an actor than i can set in the size map the dependencys to display. If i set on “game” than my dependencys looks NOW very very good. But if i show up “all” than i have up to 1.5 GB memory. Which setting should I focus on?

  2. The first screenshot shows my empty map. Its now 6.2 MB. What can i now do to reduce my memory?
    I can’t imagine that it can still be due to the map.
    Do you have any other ideas?
