So far the default field of view is very good if not perfect, no graphical glitches and it plays like a champ, but there one issue I can find so far and its a some what important:
When you access a computer console it assumes a tighter aspect ratio thus the red button to exit it is cut off at the bottom and I can't seem to find a keyboard mapping for it, you just can't exit a console, forcing a save/quit/switch res/load/do it/repeat each time which isn't fun.


Regular aspect 4:3 (1280x1024)


Triplehead aspect 12:3 (3840x024)


I know there are probably bigger fish to fry, but could we get that red button mapped to some key on the keyboard in first patch?


Btw for others trying, here's how I initiated it:
1. First launch the game's loader and establish all the visual settings you want and quit
2. Edit my documentsmy gamesFallout 3falloutprefs
3. Set the variables iSize W & H (the last ones in the [display] catagory) to your desired resolution and the game will just accept them, works great no issues except one...
(Any time you edit the visual effects it appears to re-write that file and wipes out your changes such as the resolution, hence the order to do them in)

For those of you having problems with the computer terminals being off the screen, open up my documents/my games/fallout 3 and edit fallout.ini

edit fDefaultFOV=75.0000 to 150.0000 this changes the menus FOV not the game! so the pipboy, hacking terminals and lock picking screens appear how they should look.

This worked liked a charm for me at 3840x1024

edit - If you are just installing the game, I recall that fallout.ini did not appear until I ran the game once. And I hope this helps everyone! ^^
