hi @ToasterMRVL ,
When a game/island closes there is a needs for a large amount of Virtual Memory and graphics memory this is in the PC itself and is called a page file and can be seen in Windows Task Manager → Memory. Here my page file, Virtual Memory has used 9.5 of 38.9 GB
This means that my pc will run UEFN and Fortnite together any will then be 28.9/10.0 GB .
This does mean that my PC cannot run any other application like Word/Excel/Power point
These all used virtual memory. When Winterfest was running my pc ran slow and crashed so put the Virtual Memory up to 32GB from 16GB. The automatic setting in Windows 11 in useless and when UEFN builds a large project you need 64GB.
Here is a link on how to setup virtual memory.
How to set up page file 64GB 64000
Often in the UEFN/Fortnite you see Garbage collecting in the Fortnite logs when trying to recover space for Lobby when the game is winding down.
When you enter the island code in Discover a page opens about the island and at the bottom you will see
In-Island-Transactions.
