Here are two gameplay videos of Dead Rising 3 on PC, captured in uncapped frame rate mode. The first one shows the latter part of game, where there are thousands of zombies. The second one focuses on Nick Ramos' melee combat abilities and realtime cut scene, followed by a quick tour of the in-game menu options.
These videos are courtesy of Wbacon, Capcom Digital Platforms director who explains here you can expect the game to run fine when uncapped.
@Tiz: John finds out he's Dany's nephew after countless banging sessions. He finds out who his family is, but has sex with his aunt. I'd say that's a bittersweet way to end things (9 Hours ago)
@KORNdog: I'm hearing the word 'bittersweet' being used a lot in conjunction with the ending. Could be a union of all the Kingdoms facing the long night with casualties in the millions. (17 Hours ago)
