The fanfare surrounding the HD era has been dampened down by suggestions that Microsoft is no longer demanding an HD resolution of at least 1280x720 for games released on the Xbox 360.
In the latest issue of Develop, Black Rock Studio's David Jefferies provides an insight into the balancing act required for resolution and quality, claiming that although both HD consoles support 4X Multiscreen Anti-Aliasing, it's impossible to support such techniques at 1280x720 because the overhead is too much.
As a result, most developers have to drop down to 2xMSAA at the very best due to Microsoft's conditions, "providing you weren't one of the lucky ones like Halo," as Jefferies notes. Bungie memorably reduced the resolution of Halo 3 to 1152x640, with the offset being improved HDR lighting as a result of the game employing two frame buffers.
However, Jefferies later claims in the article that Microsoft has dropped the 1280x720 stipulation, allowing developers working on non-Halo titles to make the choice between resolution and quality as they so choose.
