Unreal 5.1 perf is far far worse then 5.03 what is happening

[metalman_1]

We just move over to 5.1 and have had massive perf issues across the board. like 20-30 fps worse. Something seems very off. Are there any devs running into this, its super concerning we where at 45-60 in most area in 5.03 but 5.1 its down to 20-30.
Any help would be greatly appreciated. We can’t even use dev builds because the perf is worse then then editor. Epic please please please please stop releasing broken stuff. Your killing your customer base, these issues cost studios thousands of dollars in dev time. Its seriously getting ridiculous. help us out

I’m not sure if this is going down the right path for you, but for me, disabling TSR in my Anti-Aliasing method just about doubled my FPS, even on a blank scene. (You can find the option in your project settings under Rendering → Default Settings)
