LOD > 2.0 + true Ultra Setting - is it possible after the ultra setting bug?

I appreciate the advice im just not sure I am doing it right.

Untick “read only”
Edit Configfile
Save
Thick “read only”

I think its right. When I entered the sim it initially reset all my graphic settings so exited the sim once again and re checked and seemed to be ok.

Checked file and the amendments seemed of change.

Bar the lod is there any further settings you suggest changing in the config?
