Heaven Angel Posted June 27, 2013 Report Share Posted June 27, 2013 Microsoft showed some DirectX 11.2 stuff at their Build Conference. MS says DX11.2 is for Windows 8.1 and Xbox One only. Works on DX11 cards. Day 1 Keynote http://channel9.msdn.com/Events/Build/2013/1-001 DX11.2 at MS dev network: http://msdn.microsoft.com/en-us/library/windows/apps/bg182880.aspx One feature is "Automatic GPU memory paging/tiling" which will also work on the Xbone so I guess it comes with 11.2 support. They showed a full scene using 3GB of texture data rendered by a GPU limited to 16MB memory at the Build keynote. This feature seems to DirectX11.1 (or 11.2) exclusive.

ScrewyAurum Posted June 28, 2013 Report Share Posted June 28, 2013 [uPDATE] NeoGAF’s member ‘LukasTaves‘ shared the five key features of DirectX 11.2: - Hardware overlay support (Similar to Durango’s display panes, allows the developer to render the 3d graphics of the app at lower than native resolution, while keeping 2d ui at native res composing the final frame at a native resolution). Developers can also target a framerate and let the gpu dynamically scales the 3d graphics to try to meet that criteria (basically dynamic resolution changing is now fully supported by the api) - HSL shader linking. W8.1 store apps can compile shaders in runtime, so the behavior of the shaders can be dynamic. However compiling is slow, so this feature allows you to pre-compile shaders at build time and link them at runtime, this way you can create new dynamic shaders without the performance hit. Dynamics shaders could be used for instance for a game to test the performance of the device it’s going to run and modify to a simpler or a more complex version of the shader to maintain the best visual quality while maintaining the target framerate. It’s also useful for building shader library dlls that can be shared among different projects and each app decides how to build their shaders from this library. - Mappeable gpu buffers. This is great for compute scenarios with collaboration of the cpu and gpu. They provide api support for the cpu directly access the gpu memory without needing to copy the buffer back and forth. For 11.2 it’s going to be onlye for compute so it’s only buffers, not graphical objects. - Low latency present API. Basically api support for the system to tell the app when it’s the best time to start rendering and showing the content on screen, to allow the shortest latency possible. By using this api they were able to reduce latency from 3 frames (at 60fps) to less than 1. - Tiled Resources which is api support for hardware accelerated virtual texturing. It’s basically hardware support for mega texturing. Link to comment Share on other sites More sharing options...
Aftrunner Posted June 28, 2013 Report Share Posted June 28, 2013 I have a Win 8 Key. Probably will never get around to installing it unless..... Halo 3 for Win 8 like 2 for Vista. Link to comment Share on other sites More sharing options...
spindoctor Posted June 28, 2013 Report Share Posted June 28, 2013 The part about using system ram for texturing is really neat. The part about it being Win 8 exclusive is not. They tried this sh*t with Vista too. Only way they know how to prop up an OS it seems. Won't work, everyone will just move to Win 9 when it comes out and 8 will join Vista as the bastards of the Windows family that no one likes to talk about after some time.

praveer Posted July 3, 2013 Report Share Posted July 3, 2013 There are NO extra features in DX11.2. It's the same DX11 with some extra inbuilt tools that is possible to create separately. Link to comment Share on other sites More sharing options...
