Understood. No worries. I am maxed out on everything except for cockpit glass which is medium. 200 LOD. Motion blur is off(I hate it).
I’ve yet to be able to get a decent screenshot of my panel. I’m using a 49" wide. It never looks as good as I can see it live. I’ll probably be back on the sim later. I’ll look out for what you’re seeing.
Yepp, thats true!
Go to your UserCfg.opt file.
Edit it with Notepad.
Change Preset Ultra to Preset Custom.
Set Ultra and OPT LOD = 9 and Terrain LOD = 9.
Change any other settings you desire.
Save this file.
Display it in File Explorer.
Right Click and click Properties.
Check the box Read Only.
Click Apply and then ok
Do not touch the FS2020 Options, General Options.
See what gets displayed.
If you touch any of the General Options, this procedure is made null and FS2020 will set the graphics options to its own preference.
I’ll leave it as is for now. I’m weary about altering the internals of the sim. Gotta be patient with this.
No need.
Do not touch LOD slider.
It is worth pointing out that “Ultra” is different to “Maxed Out” . You can go higher than ultra.
For example in the options menu Ultra sets your render scaling to 100%. Taking it up to 150%, if your system can handle it, gives noticeably more readable cockpit labels and sharper instruments.
Some of the shadow settings will go higher than “ultra” sets them to.
Also, as already mentioned, playing with the config text file lets you choose LODs much higher than the max available in game of just 200 .
If you change any of the graphics settings in the options menu at all it will reset the LOD unless you make the file read only.
You are wrong 
Do not touch LOD slider.
Our systems are probably different.
If i change any setting at all and quit and then check the config file the LOD for the next flight along with some other changes like colorgrading have all been reset.
For me it happens every time.
Uncheck read-only > apply > ok
Do not touch LOD slider and global rendering quality.
Also turn off game optimization via nvidia geforce experience.

Have no idea what the ding dong you are all talking about, so I’ll leave it all alone. Thank you very much!
Basically there is a difference between Maxed Out settings and Ultra settings - more or less because Asobo slightly nerfed Ultra to avoid people whining too much about how “my mums old work PC is great in other games but only gets 2 FPS in ultra - this game sucks” .
In particular they limited the LOD sliders in the options menu to 200 maximum even though the true maximum LOD for the game if you edit the config manually is actually 800.
