Unreal Engine 4 to 5 Low FPS Problem

Hey

I have a project made in UE 4.27 and when Ue5 was realease, i try it to upgrade the project, but fps decrease allot.
I thought was about the project, but i started to make some tests.
I created a new thirperson project template in 4, i upgraded to 5 and Fps decrease again.
Any clue why this is happening?

I have a RTX 3070
Ram: 16 Gb

I will put here 2 screenshots. 1 in UE 4.27 and another 5

Thanks!
