Performance issue - UE. 4.21.2 vs UE. 4.25.4

Hello there! This is my problem…
I recently discovered that I need to switch engine versions… So I moved the whole project from 4.21.2 to 4.25.4. Not like normal import export, But I reworked all of the mechanics, structures, whole maps… Now I am having this “ISSUE” where I got poor framerate… On 4.21.2 I used to get 30-60fps normal. But now, I get hardly 10fps from a low setting. I tried scalability options, reduced texture, image quality. Pls help, I do not know what to do…

Can you link the question in your answer please.

It wasn’t really a performance issue… I just baked the lights, cleaned some blueprints up, and remove
all of the 2D camera targets… the performance is back :smiley:
