UEFN using a ridiculous amount of RAM

Summary

UEFN editor taking up 20 gigabytes of RAM even with minimum settings and lighting disabled. This has only been happening for the past couple weeks or so(although I hadn’t done much in the editor for a couple of months before that). Whenever I try to open the game view both the editor and Fortnite end up crashing because of course I run out of RAM. How can I decrease the RAM usage of UEFN?

Steps to Reproduce

I open UEFN and load up my large project.

Additional Notes

The project is very large and it has around 18k assets in it, but they are all from within Fortnite(none imported). I know that it did not use to take this much RAM because I used to only have 16 gigs(now I have 32) and it ran just fine with Fortnite open.

hi ,

Unreal Engine needs a page file of at least 64GB to build and run the engine therefore

this means you probably need an extra SDD of 128GB (128000) for additional UEFN components

How to create a manual page file

You cannot adjust parameters in UEFN like using standard engine UE 5.7
