Continuing the discussion from Post Your Screenshots!:
there was another post somewhere showing the path better;
ok, I got this from my computer - took me a while to find it; so you are looking for gameoptions file in:
steam>userdata>xxxxx>xxxx>local>usersettings>default
you change the lodSettingsIndex value to whatever you want (I use 24; apparently anything higher is hard to appreciate and will only be a burden for your PC - diminishing return basically)
xxxx in the path are folders that have a number as their name and the numbers are specific to you; the second of them number folders is the game folder; if you are unsure which of the game folders is Boundless , you can always go to steam to open local game folder for Boundless and you will see it then
