5.4.2 Crashing after windows reinstallation

I’m glad that worked out! This is a thread of users going over some possible fixes and workarounds for poor performance primarily in 5.4:

UNREAL ENGINE 5.4 EXTREMELY BAD PERFORMANCE

Hi everyone, I have upgraded my UE 5.3.1 to 5.4. And performance is extremely bad. In Version 5.3, I was getting an average of 120FPS at Normal settings and 60-70FPS at High and EPIC settings. In Version 5.4, I get 15-20FPS even at low settings. And I cannot downgrade my project to a lower version. Please help me. I have been working on this project for 6 months. Thanks everyone for help.
