Even quicker than i thought, get onto this http://www.widescreengamingforum.com/forum/viewtopic.php?p=143018#143018 you need to adjust it to X 1.31 Y 1.253 or whatever works for you. This is well worth doing the game is much more playable, especially vehicles.
Take care with using this fix - I got a bluescreen and system reboot when I tried it. Using a 8800GT with the latest WHQL drivers - no betas for me.
try this: X 1.15 Y 1.443 i have to say this has increased my enjoyment of the game immensely, why didnt ubi release it properly?
the widescreen in far cry 2 is not properly implemented, its cuts off the top and bottom of the screen and give the game an odd field of vision see this thread http://www.widescreengamingforum.com/forum/viewtopic.php?t=14737&postdays=0&postorder=asc&start=0
