Has anyone successfully changed the FOV in Bioshock 1 Classic? The default fov is kind of annoying at 1920x1080.

A search turned up a suggestion to add "fov 120" as the first line of startup.ini, and turn off the horizontal lock in the options menu. That didn't work.

Any other ideas?

Use a program called flawless widescreen. It allows you to adjust while in-game

OK thanks, that does look useful. In the meantime I found a way to set FOV in an .ini that actually works.

Add -dx9 to the Bioshock shorcut command line.
In the game graphics settings, set horizontal lock to off.

The fov commands are SetFOV nnn (100 works great for me), and ResetFOV (restores default FOV if needed).
Bind these commands to unused keys (F11 and F12 are available) in user.ini (in \appdata\roaming\bioshock\).

Works great, looks great -- dx9 actually looks much better than the default DX10 setting, and also solved the problem of having to reset brightness every time the game was started.

While I'm at it another ini fix is in the [IpDrv.TcpNetDriver] section of bioshock.ini. Change AllowDownloads=true to false. That solved the game locking up at startup.

anyway, hope this is useful to somebody. Played a few hours after making these tweaks, everything seems fine. Windows 7 64, GTX 970. FWIW I did not install the Windows 7 Platform update, maybe it's required for the remastered version but it's definitely not required for the classic.
