Put SoftTH (fullscreen, DX9 x86) in (path-to-game)\Binaries\Win32\. Edit %USERPROFILE%\Documents\Game of Thrones\UnrealEngine3\AGOTGame\Config\AGOTInput.ini. Under [AGOTGame.AGOTPlayerInput], add line: Bindings=(Name="Z",Command="FOV 109"). In-game, select massive resolution. At each gameplay start, type Z for FOV fix. Sometimes reverts (e.g. new chapter); press Z again.
