UE - Updated my project to UE4.25, its 10 times slower and lights looks worst...why?

I updated my project from UE4.24 to 4.25… and it took 3 hours… now, converted to UE 4.25, lights and materials look horrible, intense, unrealistic and FrameRate dropped from 60FPS to 24FPS…

Why? i didn´t changed anything, did unreal add something i should turn off?

This happened once in the past, i think from 4.18 to 4.19… and i think the reason was a light issue that Epic solved for the next version, but at that moment i only had an FPS drop, lights were the same… now lights and materials look really bad and cheap. for now i´ll keep working with 4.24, because 4.25 is unusable… even viewport its slow.

I had same issues - looks horrible and real-time rendering looks glitchy and completely wrong. Wondering if I am missing a new setting that needs disabled?

Same thing happened with me, and it’s loading (the game) way slower too.

Maybe they are implementing “Lumen” (UE5) and it ruinned the original light system, because even do, i do tried to fix it to work with UE4.25, i was not able to emulate the realistic look i had in UE4.24, it just looks fake, even if i try to make it work… or maybe that was the idea LOL, make Lights look terrible so “lumen” saves the world… ahaha

anyway i cant use UE 4.25, and no solution :frowning:
