Im having this problem at the moment, tried resetting oblivion.ini, did not work. The resolution is correctly set there. Tried to reset fov to 75 in oblivion and oblivionreloaded.ini. Also did not work. Reinstalled the game, pretty much tried everything I can think of so far. I'm really at a loss here. I have to add that I played the game just perfectly fine with the exact same addons. But after I did the ingame command 'saveini' so my graphic settings wouldn't constantly reset when I restarted the game; the problem happened. Any help would be greatly appreciated.
