This is a release which focuses on performance and bug-fixes.

Performance

  • Improve swapchain latency and frame pacing by up to one frame.
  • Optimize lookup of format info.
  • Avoid potential pipeline compilation stutter in certain scenarios.
  • Rewrite how we handle image layouts for color and depth-stencil targets.
    Allows us to remove a lot of dumb
    barriers giving significant GPU-bound performance improvements.
    ~15%-20% GPU bound uplift in Horizon Zero Dawn,
    ~10% in Death Stranding,
    and 5%-10% improvements in many other titles.

Features

  • Enable support for sparse 3D textures (tiled resources tier 3).

Bug fixes and workarounds

  • Various bug fixes in DXIL.
  • Fix weird bug where sun would pop through walls in RE: Village.
  • Workaround game bug in Cyberpunk 2077 where certain locales would render a black screen.
  • Fix various bugs (in benchmark and in vkd3d-proton) allowing GravityMark to run.
  • Improve robustness against certain app bugs related to NULL descriptors.
  • Fix bug with constant FP64 vector handling in DXBC.
  • Fix bug where Cyberpunk 2077 inventory screen could spuriously hang GPU on RADV.
  • Add workaround for Necromunda: Hired Gun where character models would render random garbage on RADV.
  • Fix bug in Necromunda: Hired Gun causing random screen flicker.
  • Fix windowed mode tracking when leaving fullscreen. Fix Alt-Tab handling in Horizon Zero Dawn.
  • Temporary workaround for SRV ResourceMinLODClamp. Fix black ground rendering in DIRT 5.
    The overbright HDR rendering in DIRT 5 sadly persists however :(
  • Implement fallback maximum swapchain latency correctly.

Development features

Various features which are useful for developers were added to aid debugging.

  • Descriptor QA can instrument shaders in runtime for GPU-assisted validation.
    Performance is good enough (> 40 FPS) that games are actually playable in this mode.
    See README for details.
  • Allow forcing off CONCURRENT queue, and using EXCLUSIVE queue.
    Not valid, but can be useful as a speed hack on Polaris when single_queue is not an option
    and for testing driver behavior differences.
