Microsoft announced at their Build Conference that DirectX 11.2 will only be available for Windows 8.1 and The Xbox One. We are all shocked, no really, we are.

DirectX 11.2 updated in Windows 8.1 will introduce a host of new features, including:

  • HLSL shader linking
  • Inbox HLSL compiler
  • GPU overlay support
  • DirectX tiled resources
  • Direct3D low-latency presentation API
  • DXGI Trim API and map default buffer
  • Frame buffer scaling
  • Multithreading with SurfaceImageSource
  • Interactive Microsoft DirectX composition of XAML visual elements
  • Direct2D batching with SurfaceImageSource

DirectX tiled resources was demoed, showing off the capability of DX11 video cards to use system RAM to improve texture detail. The tiled resources technology will also be used on Xbox One consoles.

It is described as the following:

“Windows 8.1 Preview includes a new Direct3D feature called tiled resources, which exposes a limited virtual graphics memory model to apps and thereby permits loose mapping between logical resource data and physical memory. This allows the creation of large logical resources that utilize small amounts of physical memory. This is useful (for example) with terrain in games, and app UI.”

In short, it makes for better looking graphics. Check out the demo below, it’s not really that impressive in this video, but I’m sure somewhere in the future we’ll all be super impressed. It’s all very next-gen.

Charles Hollemeersch and Matt Sandy hosted a great session on massive virtual textures as well, which is actually well worth watching. It explains the concept in terms any one can understand, and really gives a good look into exactly how Direct3D Tiled Resources will work.
