When questionned as to why the minimum wasn't 1080p, Rene responded that most of Europe hadn't even reached 720, let alone 1080. Because of the embedded DRAM architecture of Xbox 360, the AA was described as 'Absolutely free'. The technology fulfills all the criteria of Windows Graphics Foundation 1.0, aka DirectX 9.0c, which includes Shader Model 3.0. However, it lacks features which are required for WGF 2.0, most notably the ability to create vertices, rather than just shade and manipulate them. Whilst the architecture of the 360 is not comparable to a PC design, Rene said that the raw performance would be roughly equivalent to a 32-pipeline PC graphics card. The shared memory technology was 'Definitely not comparable to Hypermemory', ATI's shared memory technology for the PC.
