Rebellion Says Xbox One's eSRAM Too Small to Output Games at 1080p at This Time
Details on Rebellion's Sniper Elite 3 surfaced last week alongside an impressive gameplay video, but development hasn't been as smooth as Rebellion would have liked for the Xbox One version compared to the PlayStation 4 (the game will also be coming to Windows PC, PlayStation 3, and Xbox 360). Speaking to GamingBolt, Sniper Elite 3's senior producer, Jean-Baptiste Bolcato, explained that the Xbox One's eSRAM made it difficult to achieve the coveted 1080p at 60 FPS.
According to Bolcato, "It was clearly a bit more complicated to extract the maximum power from the Xbox One when you're trying to do that. I think eSRAM is easy to use. The only problem is...Part of the problem is that it's just a little bit too small to output 1080p within that size. It's such a small size within there that we can't do everything in 1080p with that little buffer of super-fast RAM."
Bolcato said his team is on fine ground now, learning to handle things in chunks and utilizing a few tricks like tiling, but that the first few months were hell. That being said, he does see it improving in the future and mentioned that Microsoft is already planning on releasing a new SDK "that's much faster" - while he was worried six months ago, he's not anymore. While the Xbox One does have 5GB of DDR3 available for games (8GB overall), the much faster eSRAM is a mere 32MB. On the flip side, the PlayStation 4 has 8GB of DDR5, which Bolcato says is "almost as fast as eSRAM" when it comes to bandwidth, and has thus made the PlayStation 4 easier to work with. Bolcato sees it evening out in the near future though, so no need to ignite a flame war over this news.
Regardless of the current differences between the Xbox One and PlayStation 4, Rebellion is still targeting 1080p at 60 FPS for Sniper Elite 3 on both consoles. Or you can always just grab the PC version and not be limited ;).
