Very rare to see this in PC games, except for some pure shooters where you often can edit it in the .ini. If it's an in-game option that's very rare indeed. Nice Bioshock, Witcher II and many, many PC games has this problem and the devs didn't seem to care.

There's even a forum dedicated for issues with widescreen and FOV settings called widescreengaming forums, there's tons of hacks or user created programs to fix many problems with PC games there, highly recommended.
