DXVK version 2.1 has been released with HDR support

On systems supporting HDR10 color spaces, HDR can now be enabled by setting the environment variable DXVK_HDR=1, or by setting the option dxgi.enableHDR = True in the configuration file. When using vkd3d-proton 2.8 or newer, this will allow D3D12 games to detect and use the HDR10 color space if they support it.


No major Linux desktop environment currently supports HDR. In order to use this on Linux, a Gamescope session with --hdr-enabled is required. This is currently only supported under AMDGPU and requires kernel patches from the josh-hdr-colorimetry branch.

Note: D3D11 support is implemented, but not expected to work in most games as they typically require AMDAGS or NVAPI to set up HDR output, rather than using the corresponding DXGI APIs. Additionally, only Nvidia drivers are expected to work on Windows.

Shader compilation improvements

Use of pipeline libraries was extended to pipelines with tessellation or geometry shaders in order to further reduce stutter. Additionally, more features of the VK_EXT_extended_dynamic_state3 extension are leveraged to reduce stutter in some situations when MSAA is used, provided that the Vulkan driver supports them.

Note: Current development builds of RADV will expose VK_EXT_graphics_pipeline_library with the features that DXVK needs if the RADV_PERFTEST=gpl environment variable is set. Note that the implementation is not yet complete and does not support shader caching at this time, but it should generally work with DXVK.

Sample rate shading

For older games that support MSAA, the d3d9.forceSampleRateShading and d3d11.forceSampleRateShading options were added to let users enable sample rate shading for all shaders. This will have a very high impact on GPU-bound performance, but may increase overall image quality in certain games that suffer from specular aliasing or shimmering alpha-tested geometry.

Note: Games that resolve the rendered images inadequately (e.g. performing a linear resolve on HDR render targets) will likely not benefit from this option.

GLFW backend

For native Linux builds of DXVK, a GLFW backend was added as a compile-time alternative to the existing SDL2 backend. See PR #3111 for details.

Bug fixes and Improvements

  • Improved D3D11 command submission logic in order to make overall performance more consistent, and to bring DXVK's behaviour more in line with native D3D11 drivers.
  • Fixed D3D11 reference counting issues around 2D textures. (#3169)
  • Fixed Vulkan validation errors when creating DXGI_FORMAT_A8_UNORM UAVs. Note that UAVs of this format may not work as expected.
  • Fixed Vulkan validation errors that would occur when allocating dedicated image memory on Nvidia GPUs in some situations.
  • Fixed Vulkan validation errors caused by broken timeline semaphores on 32-bit Proton.
  • Worked around an issue with the Uplay overlay being stuck on screen. (#3146)
    Note that this fix does not apply to Windows as it was achieved by loading winevulkan.dll directly instead of the actual Vulkan loader.
    Note that this change will break Red Dead Redemption 2 with dxvk-nvapi prior to this commit: jp7677/dxvk-nvapi@ac00a42
  • Worked around a bug in AMD's Windows driver as well as AMDVLK that would cause numerous games to crash since DXVK 2.0. (#3172)
  • Fewer threads will be used to perform background optimization of graphics pipeines. This may result in a smoother gameplay experience on some systems. Note that this change does not affect initial shader compiling, as finishing that quickly is crucial to avoid stutter.
  • The state cache file will now only be created when the first pipeline is written to it, in order to avoid empty cache files.
    This change mostly affects D3D9 games on systems with EXT_graphics_pipeline_library support.
  • Ashes of the Singularity: Fixed performance regression caused by suboptimal descriptor set allocation.
  • Battlefield: Bad Company 2: Fixed flickering (#3078, PR #3079)
  • Cardfight!! Vanguard: Fixed rendering (PR #3068).
  • Gujian 3: Fixed rendering issues on some GPUs. (#1784)
  • Resident Evil 4 HD: Fixed invalid Vulkan usage causing a GPU hang on RADV. (PR #3089)
  • Saints Row: The Third: Fixed a severe performance issue with rain when using the D3D9 renderer. (#2473, PR #3158)
  • Sekiro: Shadows Die Twice: Fixed stuttering issues on Nvidia GPUs. (#3179)
  • Sonic Frontiers: Worked around a game bug that would cause shadows to flicker when GPU-bound.
  • Supreme Commander: Forged Alliance: Fixed a crash after loading (#3058, PR #3060)

Note: The setup script was no longer deemed useful and got removed. This change will only affect users who manually install DXVK into a wine prefix, rather than using it through Proton or Lutris.

Note: Due to changes to our DXGI implementation, older versions of vkd3d-proton (prior to 2.8) will no longer work with this version of DXVK.

Wine stable release 8.0 is now available for Linux FreeBSD and macOS

The Wine team is proud to announce that the stable release Wine 8.0 is now available.

This release represents a year of development effort and over 8,600 individual changes. It contains a large number of improvements that are listed in the release notes below. The main achievement is the completion of the conversion to PE format.

The source is available now. Binary packages are in the process of being built, and will appear soon at their respective download locations.

What's new in Wine 8.0

*** PE modules

- After 4 years of work, the PE conversion is finally complete: all modules can
  be built in PE format. This is an important milestone on the road to supporting
  various features such as copy protection, 32-bit applications on 64-bit hosts,
  Windows debuggers, x86 applications on ARM, etc.
  However, some modules still perform direct calls between the PE and the Unix
  part, instead of going through the NT system call interface. The remaining
  direct calls will be removed during the Wine 8.x development phase.

- A special syscall dispatcher is used for PE -> Unix transitions, to avoid the
  overhead of a full NT system call. This minimizes the performance impact of the
  new architecture, in particular for the OpenGL and Vulkan libraries.

- Building mixed Windows/Unix libraries in ELF format ( libraries) is
  still supported for use in Winelib applications. However, such applications
  won't support features enabled by the NT syscall interface, such as WoW64
  without 32-bit libraries.

*** WoW64

- WoW64 thunks are implemented for essentially all Unix libraries, enabling a
  32-bit PE module to call a 64-bit Unix library. Once the remaining direct
  PE/Unix calls have been removed, this will make it fully possible to run
  32-bit Windows applications without any 32-bit Unix library.

- When the 32-bit Wine loader isn't found, 32-bit applications are started in
  the new experimental "Windows-like" WoW64 mode (where 32-bit code runs inside
  a 64-bit host process). This mode can be enabled by building with the
  '--enable-archs' configure option. This is still under development and not yet
  recommended for general use. Since in case of configuration errors it is
  possible for it to be triggered inadvertently, applications started in this
  mode print the warning "starting in experimental wow64 mode".

*** Graphics

- The "Light" theme is enabled in the default configuration, for a more modern
  look. Other themes can still be configured through WineCfg.

- The graphics drivers (winex11.drv, winemac.drv, wineandroid.drv) are converted
  to run on the Unix side of the syscall boundary, and interface with the Unix
  side of the Win32u library.

- The Print Processor architecture is implemented. This will be used to avoid
  direct PE<->Unix calls in the printer driver.

- Effects are supported in Direct2D, including description parsing and a number
  of core objects.

- Command lists recording and playback are implemented in Direct2D.

- The Vulkan driver supports up to version 1.3.237 of the Vulkan spec.

*** Direct3D

- Many optimizations related to streaming map acceleration are implemented, in
  common code as well as in the GL renderer. Depending on the application, this
  may result in major performance improvements.

- Adapter video memory budget change notifications are implemented.

- The Vulkan renderer supports setting multiple viewports and scissor rectangles.

- Several Direct3D 10 and 11 features, which were already implemented, are
  accurately reported through capability flags:
  - Per-format support for vertex and index buffers.
  - Per-format support for all capabilities via D3D11_FEATURE_FORMAT_SUPPORT.
  - No-overwrite maps on shader resources and constant buffers.
  - Partial range binding of constant buffers.

- For convenience, a new WINE_D3D_CONFIG environment variable may be used instead
  of modifying the HKEY_CURRENT_USER\Software\Wine\Direct3D registry key. The
  value is a comma- or semicolon-separated list of key-value pairs, e.g.:


  If an individual setting is specified in both the environment variable and the
  registry, the former takes precedence.

- The Direct3D graphics card database recognizes more graphics cards.

- The Vulkan renderer limits the maximum Direct3D feature level based on
  available Vulkan features.

*** Direct3D helper libraries

- A new HLSL compiler is implemented using the vkd3d-shader library.

- A new HLSL disassembler is implemented using the vkd3d-shader library.

- The HLSL preprocessor is reimplemented using the vkd3d-shader HLSL

- The D3DX 10 Thread Pump is implemented.

- Many more expressions are supported in Direct3D 10 effects.

- Cubemap projection is implemented in the D3DX 9 helper library.

*** Audio / Video

- The MPEG-1 audio decoder filter for layers 1 and 2, and the separate filter for
  layer 3, are both implemented on top of GStreamer.

- The ASF reader filter is implemented.

- The OpenAL32.dll wrapper library is removed, in favor of the native
  OpenAL32.dll library shipped by Windows applications.

*** Media Foundation

- Content type resolution is improved in the Media Foundation Player.

- Rate control is implemented.

- The Enhanced Video Renderer default mixer and presenter are better supported.

- The DirectShow filter is implemented in the Enhanced Video Renderer.

- An initial framework is implemented for the Writer encoding API.

- The topology loader is better supported.

*** Input devices

- Controller hotplug support is greatly improved, and controller removal and
  insertion are correctly dispatched to applications.

- Driving wheel device detection and reporting is better implemented, using the
  SDL library and HID usages as hints for the device types.

- Force feedback effect support is improved, specifically with driving wheel

- The HID Haptics specification is used for left / right motor rumble and trigger
  rumble. It makes it possible for device drivers to expose haptics support over
  HidRaw, and overcome EvDev limitations.

- The Joystick Control Panel is redesigned, with new graphics and a dedicated
  view for XInput gamepads.

- Sony DualShock and DualSense controllers are supported when the hidraw backend
  is used, and exposed to applications in the same way as they are on Windows.

- The Windows.Gaming.Input module is introduced, one of the first WinRT modules
  in Wine, implementing a new programming interface to access gamepads, joysticks
  and driving wheel devices.  For this new input API, hotplug notifications are
  also implemented, as well as force feedback effects and haptics. This API is
  the first one to support trigger rumble.

*** Internationalization

- A proper locale database, in Windows locale.nls format, is generated from the
  Unicode CLDR database. The list of supported locales is essentially identical
  to that of the latest Windows version.

- Unicode string comparison is based on the Windows Sortkey database and
  algorithms instead of the Unicode Collation Algorithm, yielding more compatible

- Characters from high Unicode planes (in UTF-16 encoding) are supported in most
  functions, in particular for case mappings, BiDi formatting, and character

- The UTF-8 encoding is supported as Ansi codepage. It is enabled when requested
  by the application's manifest.

- Unicode character tables are based on version 15.0.0 of the Unicode Standard.

- The timezone data is generated from the IANA timezone database version 2022g.

*** Text and fonts

- Font linking is enabled for most system fonts, which should fix missing glyphs
  in CJK locales.

- Font fallback in DirectWrite is reworked, with additional support for an large
  number of scripts.

*** Kernel

- The ApiSetSchema database is implemented, replacing all the api-ms-* forwarding
  modules. This reduces both disk space and address space usage.

- DOS file attributes are persistent, and stored on disk using the filesystem's
  extended attributes, in a format compatible with Samba.

*** Internet and networking

- The Online Certificate Status Protocol (OCSP) is implemented.

- More EcmaScript features are supported in JScript standard-compliant mode.

- The JScript garbage collector is implemented.

- Accessibility support is enabled in Wine Gecko package.

- Web Storage, Performance object and more event objects are implemented in

*** Mono / .NET

- The Mono engine is updated to version 7.4.0. The list of changes can be viewed

*** Builtin applications

- All the builtin applications use Common Controls version 6, which enables
  theming and high-DPI rendering by default.

- The Wine Debugger (winedbg) prints thread names in the 'info thread' listing,
  for applications that set the names of their threads. All internal Wine threads
  also set their own name.

- The QWORD type is supported in the REGEDIT and REG registry tools.

- Notepad has a status bar displaying the current cursor position. The Goto Line
  functionality is also implemented.

- The builtin console programs print data in the OEM codepage, for better
  compatibility with applications reading their output.

- The Service Control tool (sc.exe) supports the 'query' command.

*** Development tools

- The PE conversion has made it necessary to implement a new mechanism to run
  static C++ constructors in Winelib ELF applications. Unfortunately, this
  requires the corresponding modules to be rebuilt with Wine 8.0.  The rebuilt
  modules will still run correctly on older Wine versions, but older modules will
  no longer execute static constructors when run on Wine 8.0.

- In regression tests, individual checks can be marked as "flaky". This is useful
  for checks that depend on external factors such as network timings. The errors
  are still reported but not counted as failures.

- Test failure messages can be printed in color by setting the WINETEST_COLOR
  environment variable, to make them easier to spot in the test log.

- The Resource Compiler (WRC) and Message Compiler (WMC) use the locale.nls
  database to detect languages and codepages, and thus support all the Windows

- The WineDump tool supports printing the contents of Enhanced Metafile spool
  files, as well as more contents from PDB files.

*** Build infrastructure

- PE binaries can be built for multiple architectures from the same build tree,
  using the '--enable-archs' option to configure, for example
  '--enable-archs=i386,x86_64'. This can be used to enable the experimental
  WoW64 mode, where 32-bit applications can run without any 32-bit host
  libraries. Note that this mode is still under development and not yet
  recommended for general use.

- Data types that are defined as 'long' on Windows are defined as 'long' instead
  of 'int' on all platforms with a 32-bit long type. This is more compatible, but
  it can cause printf format warnings with Unix compilers. In Winelib code, it
  can be disabled by defining WINE_NO_LONG_TYPES.

- Import libraries can be generated without using dlltool, by passing the
  '--without-dlltool' option to winebuild. This is used to avoid dlltool bugs
  with delay import libraries.

- Libraries that contain only resources and no code can be built with the
  '--data-only' option to winegcc, which makes them smaller and more efficient to

*** Bundled libraries

- Faudio is updated to the upstream release 22.11.

- LCMS2 is updated to the upstream release 2.14.

- LibJPEG is updated to the upstream release 9e.

- LibMPG123 is updated to the upstream release 1.31.1.

- LibXml2 is updated to the upstream release 2.10.3.

- LibXslt is updated to the upstream release 1.1.37.

- Zlib is updated to the upstream release 1.2.13.

*** Platform-specific features

- 64-bit time_t is supported on 32-bit Linux with recent Glibc versions.

- Exception unwinding on ARM platforms is extended with EHABI support on ARM32
  and Dwarf support on ARM64.

*** Miscellaneous

- RSA encryption and the RSA-PSS signing algorithm are implemented.

- An initial version of the UI Automation API is implemented.

- Function name demangling supports various C++11 features.

*** External dependencies

- The vkd3d and LDAP libraries are bundled in the source tree and built as
  PE. The corresponding Unix libraries are no longer needed.
