That mod automatically changes the FOV to whatever's appropriate, which is why other settings won't stick for you, but maybe something's wrong or there's a bug somewhere.
I'll definitely be taking a look at it, because I'm not sure where this bug could be coming from.
I assume you're playing it in fullscreen mode, correct? Do you have multiple monitors or anything like that? Could you upload a screenshot to someplace like imgur.com? Does running it as administrator help? Really, any information you can give me helps.
I'll download the posted version of my mod and tool around with it a bit to see if I can spot what might be wrong.
EDIT: Okay, I'm looking into it and there's definitely something wrong. Hopefully I'll have it fixed at some point today.
DOUBLE EDIT: I know what the problem is and I'm working on it. Will upload a new version in probably a few hours.
TRIPLE EDIT: Problem solved, new version uploaded. Unfortunately, the FoV doesn't get adjusted until after the main splash screen, but that's a minor annoyance. I'll probably find a workaround for that in the near future.
