720p requires more than 10.3MB. (4 bytes of color + 4 bytes of z/stencil) * 2 (AA) * 1280 * 720 = 14.7MB.pakotlar said:Well, whether or not you "think" tiling would be necessary doesn't change the fact that it is necessary. Read Beyond3d's article on the Xenos for a quick refresh. I'm sure there are some whitepapers floating around to prove this to you as well. AFAIK, 2xAA @ 1280*720P takes about 10.3MB.
edit: Did you read what you just said? How would sending the geometry through twice alleviate the fact that the memory address size exceeds the EDRAM framebuffer? Are you sure you aren't talking about predicated tiling?
