Xbox One: 1080p “comfortably” with SDK update, says Rebellion

With the announcement of Respawn Entertainment’s Titanfall joining the roster of games on Xbox One below the widely-hailed 1080p mark; gamers have taken to their favourite venting areas to take pot-shots at the competition...

As a Microsoft-platform exclusive, many see the failure of the highly-anticipated title to be 1080p as an indication of a lack of graphical processing grunt in the Xbox One compared to the PS4.

Rebellion Games, as a cross-platform developer, has added their take…

Jean-Baptiste Bolcato, Senior Producer, said to Gaming Bolt: “eSRAM is easy to use. 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.”

The producer is speaking about the criticism of Microsoft’s choice to utilise a smaller but faster type of RAM - which when used in combination with the console’s DDR3 RAM - can provide a higher bandwidth capable of 204GB/s (For comparison, PS4's DDR5 has a max throughput of 176GB/s.)

Many developers have not had the experience in dealing with such an (initially) small pool of memory – especially when doing everything in 1080p. It is possible, as Microsoft themselves have shown in first-party title Forza 5 which also runs at the targetted 60fps.

But when PS4 titles such as Killzone: Shadow Fall are using 800MB for render targets alone; how difficult will it be for developers to work with just 32MB of fast memory for similar functions?

‘Tiling’ is the solution. At Microsoft’s BUILD event last year; the team showed hardware-based tiled resource support added in DX11.2. Without going into all the technical talk - available here - 3GBs of textures were able to be stored in 16MB of RAM. To point out the obvious, 32Mb can store up to 6GB worth…

Bolcato stated: “It’s a bit like the reverse of the PS3. PS3 was harder to program for than the Xbox 360. Now it seems like everything has reversed but it doesn’t mean it’s far less powerful – it’s just a pain in the ass to start with.”

Whilst DeveloperTech is yet to take a look at the upcoming SDK update for the Xbox One; it sounds as if Microsoft has made many improvements to enable developers to hit 1080p…

“They [Microsoft] are releasing a new SDK that’s much faster and we will be comfortably running at 1080p on Xbox One. We were worried six months ago and we are not anymore, it’s got better and they are quite comparable machines.”

The studio is currently in the process of developing a sequel to the much-loved and graphically-intensive -- ‘Sniper Elite’ series. This has pitted the company in the perfect position to comment on the state of both systems’ development in an unbiased manner.

Do you think we’ll see more 1080p games as a result of the upcoming SDK update and experience of eSRAM?

wow i knew it . It reminds me of ps3 when it iniatlly had games with poor graphices compared xbox 360 but as developer got used with the architecture the ps3 then started to gain momentum exactly same thing will happen this generation.
