The very first battle outside the New Tristram gates brings this to the fore quite visibly, and also drags the frame-rate down to the lowest point possible on either platform. Even with the absence of v-sync, the PS3 produces a sustained 40fps as the enemy horde rises from the outskirts of the town, generating an uneven sensation while moving our Barbarian character. The 360 fares much better here overall by bottoming out at 50fps with likewise tearing.
Fortunately, this is an exceptional case reserved for this opening section, plus some of the more extravagant boss battles such as the run-in with the Skeleton King. While overworld areas like the Old Ruins and Cemetery of the Forsaken play out with occasional dips to varying degrees on either platform, for the majority of the dungeon-crawling experience the game delivers on the 60fps promise with zero tearing.
