Its possible, although shinen and also the guys behind project cars seem to be trying to get must of the system On purpose, shinen also has revealed that they are using triple buffering for the defered rendering, they say that they need 3.6MB * 3buffers for the defered rendering(likely are g-buffers as they are very well suited for this technique). I heard that g-buffers for the defered rendering take a lot bandwidth, but didnt expect it to be higher than the 720p with double buffering which shinen mentioend was about 7.1MB of wii u edram
G buffers take a lot bandwidth, even crytek admitted that in ryse there wasnt enough bandiwdth on the esram of the xbone for complete msaa(although this one doesnt take that much memory bandwidth compared to the framebuffer) due to the use of g-buffers |
Yeah, they said some time ago that the Wii U's large eDRAM made their new engine possible, and deferred rendering and triple buffering seem the logical culprits. They've also said in the past they use eDRAM as a fast scratchpad for some GPU and CPU work.
