PS4 now have more control of their gameplay experience in Killzone: Shadow Fall.
Today’s v1.90 patch introduces amongst other things the option to lock the game’s campaign mode to 30 frames per second.
Said Guerrilla: “To guarantee a steadier framerate in the campaign mode, players can now lock their game to 30fps via the options menu.”
There are a number of other principally-online additions, too, such as improved in-game clan functionality, new Warzone options, extra checkpoint saving and a fix to the VC30 flashlight fix.
