Another build where the extremely slow compiling and freezing caused by engine hogging 100% cpu hasn’t improved. Will the team ever acknowledged the issue and add some much needed optimization?

This has been an ongoing issue for ages now since something change around version 4.19. As far as i know it’s never been noted by unreal devs even though it’s clear it got much worse since then.

I upgraded from an i5 which was enough at one point but even now i got a new ryzen cpu it still takes ages and can freeze up. Can’t we run compiling on the gpu or get some sort of optimization as it’s become a joke honestly with the time it’s taking? I just hope something changes in UE5.

I agree that know it’s never been noted by unreal devs even though it’s clear it got much worse since then.
