A Steam Community post outlines how to unlock the framerate in Metal Gear Solid: Ground Zeroes, allowing enterprising gamers to surpass the 30/60 frames per second cap in the PC edition of the action/adventure sequel (thanks DSOGaming). This is accomplished through the deletion of a single line of code in a configuration file, though obviously you have no one but yourself to blame if doing so triggers a nuclear launch or chronic acne, as this is unsupported. There are also instructions in that thread on how to unlock the game's field of view, and more on messing with the PC edition can be found on NeoGAF.
