Version v1.31

This version contains some quality of life fixes and expanded SPIR-V debugging support, as well as a new mesh visualisation feature. There are also some important bugfixes for D3D11 and mesh shader usage, and a workaround for a recent nvidia driver bug.

NOTE: Recent AMD drivers have a problem that for Vulkan and GL may cause problems creating swapchains. On UE5 this can cause fatal errors on or shortly after startup when using Vulkan, and this may also appear as the use of D3D12 in applications that don't use the API. This is an AMD driver issue which has been reported and is planned to be fixed on the AMD side.

As always binary builds with installers, zips and tarballs are available on renderdoc.org.

Main highlights

• The UI now has a configuration option to set consistent formatting of byte offset and size fields in the UI.

  By default such fields are displayed as decimal numbers up to a threshold value and then larger values are displayed as hexadecimal, but with the configuration option it can be forced to be either always decimal numbers or always hexadecimal.

• The SPIR-V debugger now supports debugging of shaders using the buffer device address extension.
  Pointers in this fashion are displayed the same way as GPU pointers elsewhere in the UI, with a resource link that jumps to a buffer viewer with the given pointer type.

  

  

• Added a new 'mesh exploder' visualisation feature contributed by Dan Hawson which allows visualisation of mesh topology via a tweakable per-vertex offset. This can show poor or good vertex sharing by revealing vertices which share positions but are distinct.
  
  

Python API changes

• SolidShade enum has been renamed to Visualisation, and similarly the solidShadeMode member of MeshDisplay is renamed to visualisationMode.

Features/Improvements

• UI: Messages suggesting enabling API validation for more error information now direct to Open Capture with Options to discourage permanently enabling validation.
• UI: Only show byte range for a single subresource when viewing texture as buffer.
• UI: When switching between mesh shader draws and compute shader dispatches, preserve pipeline state flowchart.
• Vulkan: Fail instance creation if RenderDoc layer is explicitly enabled.
• Vulkan: Add support for 64-bit selectors to OpSwitch statements.
• Vulkan: When 'ref all resources' is enabled, ensure internal buffers aren't included.
• D3D11: Improve handling and checking for unsupported sparse textures.
• Android: Add workaround for broken Android devices that don't properly support layers in apks.
