It looks PS3 owners would be getting a better looking port of Battlefield 3 than Xbox 360 owners will be entitled to. This isn’t because DICE wants to discriminate but because of the fact that the PS3 version of Battlefield 3 will support SPU-based deffered shading whereas the Xbox 360 version will only have tiled-based deferred shading.
DICE cites the reason as being the Xbox 360 not having SPUs, however it appears this will provide a better experience for PS3 owners as it’ll enable them to produce better visuals as having the ability to use the SPU+GPU together “raises the bar.” This also enables to offload some of the SPU’s work to the GPU, providing them with more space to create better looking shaders and environments.
Although, DICE says they’ll be able to use some of 360′s CPU power to offload its GPU’s work to an extent, it still wouldn’t provide them with the same level of freedom that having a dedicated SPU-based deffered system will for the PS3.
