Hello. Recently, I've been testing the tweaks (edit game .ini file), and they don't seem to improve or increase the game's texture quality and draw distance, regardless of setting the .ini file to read-only.
Furthermore, when modifying the command lines with the indicated values, the game interprets these values as unknown and appears to apply the lowest default values of those graphical settings.
I'd suggest checking the effectiveness and usefulness of these video tweaks and their eventual removal.
Regards.
