BioShock Widescreen Slices Vertical View
by Nick Breckon, Aug 21, 2007 11:03am PDTIn a rapidly-expanding thread on the 2K Games forum, reports are
coming in that 2K Boston and Australia's just-released shooter BioShock (PC, X360) uses a cropping method for its widescreen display, cutting down on the vertical view rather than expanding the horizontal width (illustrated left). The problem apparently exists for both the PC and Xbox 360 versions, and cannot be fixed with an edit of the game's FOV (field of view) setting.
The issue took forum goers by surprise, as 2K Boston lead programmer Chris Kline assured fans last May that BioShock's widescreen view would show more, rather than less. "The game will render in full 16:9 aspect ratio, with no letterboxing unless your resolution is not true 16:9," Kline said in a thread on the 2K forums. "You will see more in widescreen. We use a different projection matrix; there is no squashing or stretching of the image involved." Shacknews can confirm that the problem exists in the PC demo of BioShock, and has contacted 2K Games for comment.

Facts:
* The FOV if being calculated primarily horizontal instead of vertical.
* This results in seeing less of the environment vertically in widescreen.
Now, there are two explanations:
1) It was a fuckup because all of them play on 4:3 monitors. If FOV's are specified horizontally, then you have to do extra math to get the vertical FOV in 4:3, then do the 16:9 aspect ratio calcualations. They may not have done this calculation and nobody complained during test.
2) It was intentional. This could simply be because when you open up the horizontal FOV, you have to bring in your near clip plane to compensate. Doing this could cause Z fighting. Also, you have to check every cinematic and make sure that you suddenly aren't partially through a wall or anything. 16:9 is annoying if you don't develop for it up front.
Either way, yeah, probably a fuckup and something worth fixing, but for eff's sake, stop speculating on the cause of the problems if you don't know what you're talking about. Just complain about the results that you don't like and it'll probably get addressed in some way.
