I made some testing, and it’s still hard to answer on all these questions.
- No, it’s also happens when the main map is open, where all the Bps are, and no BPs tabs are open.
- No.
- Always, if the main map is loaded, or BPs tabs are open, even on empty map.
- No, it not even occur in my main project, if empty map is open on project start.
- Don’t see a reason for that, at some point it was 3GB+ eating memory on my really small project, which at normal rate eat 800mb-1.2GB at max. And also I watching memory usage at ue4 itself(It can be toggled at performance, if I recall correctly) but at task manager the memory usage for ue4 is almost the same.
Also I wanted to point out, that the memory leaks really slowly, as I said before, 1-3mb per second, and sometimes it stops for a few seconds, and then continues. So it takes about 10-25mins to get 2-3GB memory usage.
I tested my project on other computer, and result was the same.
