UEFN 40.00 is easily 300% slower than previous version

Summary

I don’t know how to “repro” this outside of the experience I am having since 40.00 in comparison to the previous version working on a single project. While before it would take a long time (easily 3 mins to push just verse changes), now takes up to 8 or 9 mins to push just verse changes.

Also, UEFN is now consuming pretty much all my computer resources making the rest of my apps running (including fortnite itself) to be laggy and slow and unresponsive.

To put in layman’s terms at this point, UEFN is an absolute PIG on resources of CPU and memory for no discernible increase in functionality or improvements itself. It’s as if there is some kind of horrible loop running, or a miscalculation of how memory is used within it. Creating and building in UEFN has become almost a miserable experience on my machine that has 16GB RTX4090 with a 13gen I9 cpu and 32 GB or memory.

This is unacceptable at this point and I really hope that there is some kind of change in the UEFN dev team to make this software BETTER instead of successively worse each iteration as we spend hours per day just simply waiting to push a small change.

Hello @GraemeBB

I come to you with requests for assistance from the team. :wink:

Could you please give us an island code for one of your large projects so we can start investigating? Also, if we could get both your client and editor logs after you open one of the projects where this is happening.

Feel free to send here or on Discord.

Thank you, as always!

The island code is 9664-2937-0308. I’ll see about getting logs too.

Thank you!
