Version v1.8

This release continues the plan of shipping a stable release every other month. As well as the usual batch of bugfixes and minor improvements there is one big ticket feature added:

Thanks to Steve Karolewics who has been working hard over the last 6 months, D3D12 now has the same shader debugging support that D3D11 has had for many years. This includes every feature already present, as well as support for the new SM5.1 bytecode format that's D3D12-exclusive.

It is accessed and used in exactly the same way as D3D11, vertices can be debugged from the mesh viewer and pixels from the texture viewer. Compute threads in dispatches can be debugged from the pipeline state, though note that the same proviso exists that only one compute thread is simulated when being debugged.

Binary releases are available on with zip and installer for Windows and binary tarball for linux.

Main Highlights

  • As mentioned above, D3D12 shader debugging is now fully supported, including support for the new SM5.1 and resource array indexing:
  • If RenderDoc is associated with DDS files in windows explorer it will now generate and display thumbnails for them. This supports compressed block formats using AMD Compressonator:
  • Vulkan capture and replay performance should be improved, especially for applications with large amounts of memory in use.

Python breaking changes

  • Some settings from the PersistantConfig class have been removed and moved to a new centralised settings system shared with the core module and so available at all times rather than just in the UI program. These are:
    • ShaderViewer_FriendlyNaming - moved to DXBC.Disassembly.FriendlyNaming
    • Android_SDKPath - moved to Android.SDKDirPath
    • Android_JDKPath - moved to Android.JDKDirPath
    • Android_MaxConnectTimeout - moved to Android.MaxConnectTimeout
    • ExternalTool_RGPIntegration - moved to AMD.RGP.Enable
    • ConfigSettings - removed aside from shader.debug.searchPaths which was moved to DXBC.Debug.SearchDirPaths.
  • The D3D12 pipeline state representation has been refactored to be root-signature centric and contain bindings and tables off root signature entries, compared to the previous layout that unpacked everything into register spaces and registers.
  • To be more python friendly, texture swizzles in pipeline states are moved from a C array which didn't bind well to python into a struct that contains red, green, blue, and alpha members.
  • SigParameter now has a VarType member varType instead of a CompType member compType to allow more flexible representation of signature elements.
