Thank you for the response. The Fallout4_Default.ini does exist in the Game Directory and it is populated. I used BethInI to set up and manage my .ini files through the ini path setting (via the MO2 profile route as recommended). All three .ini files are populated correctly in the MO2 INI Editor, and that is sufficient for me. For now the game with the fixes and a few core mods (Unoffical Patch, MCM etc), seem to run stable. I will do the textures etc tonight, and see where we get.
