The latest tool for debugging shaders now ships as a feature in Microsoft Visual Studio, called Visual Studio Graphics Debugger.
This new tool is a replacement for the PIX for Windows tool. Visual Studio Graphics Debugger has greatly improved usability, support for Windows 8 and Direct3D 11.1, and integration with traditional Visual Studio features such as call stacks and debugging windows for HLSL debugging.
For more info about this new feature, see Debugging DirectX Graphics.
