The latest update rollup for windows media center 2005 (was released just over a month ago) adds support for the xbox360. Notice in the picture of the remote it also has the green button.
quote:Unfortunately, we have yet to hear from Microsoft if this means that all games must be internally rendered at 1280 x 720 or if they can be rendered at a lower resolution and upscaled later on. There have been discussions involving at least one Xbox 360 game (Project Gotham Racing 3), rendering internally at a lower resolution and having the Xbox 360's TV encoder upscale it to 720p.
quote:For those wondering why this information would be true, here's the technical reason for why the game would probably be running at 1024x600 interally. On the Xbox 360, there is a thing called DRAM which serves as the framebuffer for the image. It has 10MB of DRAM, which means it can store a 10MB image, and the advantage is that it can render that image very fast (this is what gives the Xbox 360 it's "free" AA capability). Now the thing is, that 10MB can only store a full HD image (1280x720 and above) WITHOUT Anti-aliasing. So, they have a system where games can split a frame into seperate sections called tiles so that each tile would fit into that 10MB of DRAM. However, tiling is something that may have to be planned for early in the game's development, and the final Xbox 360 development kits (which were the only ones to include the DRAM) were only made availible a few months ago. In turn, Bizarre may not have had time to build tiling into the game, and therefor wouldn't have been able to enable anti-aliasing when it's running at HD. So instead, what they've likely done is lowered the resolution to 1024x600 and enabled 2xAA (which coincidentally fits into the 10MB DRAM buffer perfectly), which allows them to use anti-aliasing without adding tiling into the game.

People unfamiliar with the trademark generally use the term star, as in "star screwdriver" or "star bits." The generic name is hexalobular internal driving feature and is standardised by the International Organization for Standardization as ISO 10664.
quote:There are 48 shader units in the Xbox 360 GPU, but given that we're dealing with a unified shader architecture, you can't compare that number directly to the 24 shader pipelines of the GeForce 7800 GTX for example. We roughly estimated the power of the Xbox 360 GPU to be similar to that of a 24-pipeline ATI R420 GPU.
