I got an odd thing going on with FPS in my Fallout 4 game.
If I do the settings myself by editing the .ini files I get 20-40ish FPS.
If I use nVidia Experience to set the settings I get 39-70ish FPS.
Even after Experience have set the settings, if I go in to the .ini to disable something like Lens Flare, I get the low FPS again.
I thought Experience just edited the .ini files.
I "need" to use Experience because it's the only way I've been able to get 21:9 ratio with acceptable FPS.
Fallout 4 Launcher doesn't support 21:9 ratio.
I hope someone has some insight into what is going on.
