So if the game is running this poorly when it's single-player, is it going to drop even lower in co-op? The biggest issue seems to be the number of zombies on screen, so if that remains the same perhaps it won't dive even lower, but if effects are also having an effect I can imagine a second player is only going to exacerbate that.
It's unfortunate for those who were looking forward to this game, and hopefully the next Dead Rising can be built for next-gen and not suffer such performance problems. They really are unforgivable. While the number of zombies on screen is quite impressive, there's no reason for it to be dropping to such extremes. When they started talking about 720p and 30fps, I thought it was strange but believed it would be in the interests of really filling the screen with undead, really pushing that number up and making a more exciting experience getting trapped amongst such an overwhelming number. But it seems that, while there's more, the only thing that player can really do is run them over in huge hordes. Nobody is going to spend the time punching their way through all of that, and honestly it's not a jump like the first Dead Rising, where it felt like there were hundreds before you, especially in that underground parking area.
