What Type of Bug are you experiencing?

Stability

Summary

When opening projects before, UEFN was much faster and it never calculated shaders, a thing that I liked cause I never had an issue with shaders anyway.

Now, opening UEFN will lag my PC to oblivion, with CPU on 100% for multiple minutes, everytime I would change scalability (didn’t happen before).

Now idk what was the reason for the change, but I 100% need the old way of not calculating it, because UEFN doesn’t have to render much anyway, live edit is the one doing the work. UEFN is there for me to see what I am building.

Steps to Reproduce

Open any heavy project in UEFN
Change scalability

Expected Result

Shaders calculating step is skipped

Observed Result

Shaders calculate for multiple minutes and take 100% CPU
