That's very helpful, thanks. I was tuning Fallout 4 because City fps is terrible. Setting Ultra High or Ultra Low still city fps plummets. So I was fiddling & some how got it to run 60fps all the time in the city & everywhere with Vsync on of course PresentInterval=1. Anyway so what I did was I have a simplified Default.ini that I modded & simplified & deleted the prefs.ini & started the game & then the game was running at 60fps without a prefs at all, like the engine or something generates some way better config?!? Anyway it was 60fps without a config in the city (auto generated, I guess) so I exited & this really strange extremely messy prefs.ini was generated which has some how allowed the game to run 60fps all the time. Rather than plummeting all over the place. The Fallout 4 game is really strange when it comes to performance & configs. https://www.nexusmods.com/fallout4/mods/21470/

Did you find out more about these variables in the ini? I can't quite even begin to see if the FadePercentDefault= even works? it says 4.0 on Skyrim & 1.2 on Fallout 4 & changing it doesn't seem to do anything? I'm really focused on City FPS & what I have found to improve it is legit all low but 1920x1080 TAA x16 AF & set prefers By setting it to 0 on an original Default.ini & a Launcher Generated Ultra Low Prefs can improve the terrible FPS drop in the city from 15 fps to like 45 fps but it's still not perfect. Any advice would be appreciated. fMeshLODLevel1FadeDist=0 fMeshLODLevel2FadeDist=0
