Turning on frame rate smoothing does nothing with 120 fps as minimum and 160 as max (my monitor is 4k 160hz) but it changed nothing.
After opening unreal insights, I figured that this was a CPU issue. So I opened the bios and reset it to factory settings, and only enabling expo 2.
So I reran unreal, and hit play as a PIE new window, and I only a very unstable 60-90 fps… until I minimized the unreal editor, then I got 160+ fps.
I am not sure why my main pc is this inconsistent. Even opening an empty unreal project gives me the same amount of fps as my main project. But when I run my project on my MacBook pro m4 pro, it is consistent and has a very stable 120 fps
I might just live with 90 fps I guess, thank you for the reply
