Whilst DirectX 10 hasn't even had time to bed itself into the mainstream gaming world just yet, Microsoft have already unveiled some spicey details about an update to it, DirectX 10.1.
The most highlighted change is that of a new audio API they call "XAudio2", this to replace the oldschool "DirectSound" system which was given the flick when Vista came along (hence Creative's Alchemy project).
Microsoft is making a tech-demo version of its upcoming DirectX 10.1 available via download, including a version of XAudio2, the company's cross-platform replacement for DirectSound.
Users can try out both via the 468-Mbyte version of the August 2007 DirectX SDK. There's a catch, though: the August 2007 Direct3D 10.1 Tech Preview requires the Windows Vista SP1 Beta which will be available to MSDN subscribers once it is publicly released, according to Microsoft.
