I found out that in some situations the user.cfg write wrong data.
Check the user.cfg if the settings match the UI settings after exit.
In my case i had several times changes that affect lower quality at next start.
I had no HDR enabled in WIN10 and the UI and in the user.cfg HDR10 was enabled set to 1.
Windowed mode was set on 1 not 0 and monitor 0.
Several quality entries about AA was not at max.
Tipp:
Terrain and Objects LOD I would let at 2.0 for both.
Wit terrain LOD 2.3-.2.5 it’s at high FL and none dense areas possible.
For VFR low altitude and heavy photogrammetry more as 2.0 terrain/objects LOD could become unplayable.
Post processing is a a user choice,
I set all to 0 exclude color grading and eye adaption.
And post processing enabled 1.
Get best results for me.
How the user.cfg works:
0 is OFF and 1 is on.
1 is lowest quality and 3 mostly max.
After changes save the file. Any changes in the UI after start could set the user.cfg to unexpected different settings.
So after editing the user.cfg it’s mandatory to not change in game graphic settings in the UI.
After all a texture super sampling setting in the graphic UI of 8x8 is helpful for good quality. 6x6 is one part of a good 30FPS ultra setting at 4K with 2060/2070/2080 Gen.
The master user user.cfg is in all drive installation variants on the main drive WIN10.
