Last Few Weeks on DirectX Shader Compiler (2017-11-07)

Proudly presenting: Fixes, SPIR-V improvements and bunch of new issues filed – thanks czw831024 and simontaylor81 for the awesome reports! More work on denorm support and float16. For those of you who want to experiment with the compiler, in addition to the extensibility APIs, you now have access to experimental function attributes. These will fail…


Last Week on DirectX Shader Compiler (2017-07-26)

A lot of activity this last week, as usual here are some highlights. Some dia improvements, including the ability to dump debug info in dndxc and to compiler using d3dcompiler_47. More PIX supporting functionality available. Lots of linker improvements. Lots of SPIR-V code generation activity, including full translation for pass-through VS and constant PS. Also,…


GPUs in my task manager

Bryan Langley has posted about GPUs in the task manager. Definitely worth reading, as there are a number of reasonable but non-obvious decisions on how to best display aggregate data, and when shared resources are counted multiple times or not. Also having the driver version and DirectX version handily under the charts is very convenient,…


PIX on Windows (beta) released

Tools are an incredibly important part of our work. Great tools allow us to look at the systems we’re developing, get a holistic sense of what’s going on and then zoom into the details we care about. Today PIX on Windows announced its beta release. If you work with D3D12 on Windows, you definitely owe it to yourself…


Performance considerations for DirectX 12 on NVidia hardware

I posted a link to similar content last week for Intel. The Do’s and Don’ts list from at the NVidia site covers additional content for NVidia hardware, and includes other considerations for command lists, engine architecture, swap chains, etc. Enjoy!


Performance considerations for DirectX 12 on Intel hardware

Wolfgang Engel writes Performance Considerations for Resource Binding in Microsoft DirectX 12 for the Intel Developer Zone site. There is some good information there and some material to think about various tradeoffs that can come in handy. Enjoy!


HLSL and Visual Studio

Tim Jones has recently published a Visual Studio extension that adds a number of features to the HLSL editor – HLSL Tools for Visual Studio. Read the announcement for details on what’s available: much better navigation and errors as you type are my two favorites. You can find the extension in the Visual Studio Gallery…


Graphics Education

So, learning about graphics is a journey (a life journey, for some!). Books, papers, samples, games, demos, friends… Here’s a new resource you should probably subscribe to if you’re into that: the Microsoft DirectX12 Graphics Education channel in YouTube. Yes, it has stuff on DirectX12 specifically, but you’ll also find videos on porting from DirectX11…


Channel 9 – OpenGLES on Windows with ANGLE

Going Native has a new video about OpenGLES on Windows with ANGLE, specifically how to get going with OpenGLES for Windows Store apps. Get a bit of history as well as a walkthrough of what you get from NuGet packages and how to glue things together, all courtesy of Cooper. Enjoy!


Performance for building OpenGL ES and ANGLE shaders

Today’s note is a simple reminder that if you’re using OpenGL ES and/or ANGLE, you’re not exempt from the performance concerns I’ve discussed before. Launching quickly is still important for user experience, and developers want to provide a good first impression! The classic OpenGL ES model is to compile the shaders from text. There is…
