Microsoft just released their GDC 2007 presentations (download), with information on subjects such as XACT Audio, Direct3D10's basics and materials, LIVE on Windows, and tons more. What might be even more interesting to TechAmok readers, however, is the first presentation on the list entitled 'The Future of DirectX'. The first topic covered is DirectX 10.1 which, as previously thought, seems like a minor and logical evolution of DirectX 10.0; the new features include per-MRT blending modes, better MSAA control, Cube map arrays, more VS input/output attributes, and improved precision requirements. All in all, nothing revolutionary, but perhaps still some goodies very useful in specific scenarios. Beyond that, however, things get a little more interesting. Microsoft says it plans to integrate general-purpose GPU-friendly features like double-precision arithmetic and improved memory access into future DirectX versions. The company also mentions dynamic global illumination and ray tracing in its list of future image quality improvements. Intel called ray tracing 'the future for games' at its Fall IDF last year, so it's interesting to see Microsoft riding the same bandwagon.
