Dxvk Versions Save

Bug fixes and Improvements

• DLSS should now work in supported games in combination with dxvk-nvapi.
• Optimized D3D9 shader constants by relying on VK_EXT_robustness2 and removed the old app options for games using software vertex processing. (#2282)
• Added an option for more accurate emulation of D3D9 floating point behaviour and enabled that by default for a bunch of games. (#2294, #2359). This fixes issues in Red Orchestra 2, Dark Souls 2 (original version), Dog Fight 1942, Bayonetta, Rayman Origins, Guilty Gear Xrd and Richard Burns Rally.
• Fixed a DXGI issue which would sometimes cause games to fail to enter fullscreen mode on some displays that do not support low rates across all resolutions (#2395).
• Black Mesa: Fixed a regression with shadows. (#2317)
• Crysis 3 Remastered: Worked around poor performance. (#2339)
• Euro Truck Simulator: Fixed a shading issue resulting in black geometry (#2312)
• Injustice Gods Among Us: Fixed missing characters on the character selection screen. (#2332)
• Rocksmith 2014: Fixed white screen on startup. (#2383)
• Spliter Cell: Chaos Theory: Fixed brightness with the shader model 3 option. (#2340)
• Sim City 2013: Fixed rendering.
• The Guild 3: Fixed artifacts in overview map (#2380).

Bug fixes and Improvements

• Reduced overall CPU overhead in D3D9.
• Fixed various failures in wine's D3D9 tests.
• Fixed various issues when the d3d9.evictManagedTexturesOnUnlock option is enabled.
• Fixed various issues when the d3d11.relaxedBarriers option is enabled.
• Call of Cthulhu: Fixed reflection rendering (#2248)
• Crysis 3, Homefront The Revolution: Worked around poor performance (#2256) (#2241)
• GODS: Fixed gamma curve (#2250)
• Total War Medieval 2: Fixed black lines on the world map (#2258) and settings text (#2247) The game still crashes when loading battles due to running out of address space.
• Fantasy Grounds: Fix incorrect rendering (#2251)
• Need For Speed Heat: Fixed ground textures rendering incorrectly (#1764).
• Paranormal Files: Fix black screen (#2192)
• Pathfinder: Wrath of the Rightous: Fixed GPU hang in loading screen. Note that the game itself has further issues loading certain parts of the game, which do not appear to be related to wine or DXVK in any way.
• Payday: Fix flickering reflections (#2259)
• Shin Megami Tensei 3: Fixed hang when entering save room (#2161)
• Sine Mora EX: Added 60 FPS lock (#2261)

Bug fixes and Improvements

• Fixed a number of performance and stability issues introduced with the D3D9 locking rewrite in 1.9 (#2142, #2149, #2150, #2164, #2168).
• Rewrote the way staging textures are handled in D3D11. This can reduce memory usage and the number of image copies necessary to move data between the CPU and GPU, and fixes severe performance issues in Roblox on Nvidia GPUs.
• Removed some workarounds for very old Mesa versions (19.0 and older).
• Reimplemented locking primitives based on Windows SRW locks. This may be more efficient compared to the winpthreads implementation in mingw builds.
• Earth Defense Force 5: Work around performance issues caused by the game frequently turning vertical synchronization on and off between frames (#2127)
• Far Cry 1: Spoof Nvidia GPU in order to enable higher-quality water rendering.
• Far Cry 5 and other Dunia Engine games: Fixed various issues due to uninitialized memory (PR #2137).
• GTA IV: Fixed broken app profile that would break the game on Nvidia GPUs.
• Risen 3: Fixed crash on Nvidia GPUs (#2154).
• World of Final Fantasy: Forcibly disable MSAA to work around game bugs. Note that this should not impact visual quality since the game only uses MSAA for full-screen passes where it has no effect (#1216, #2136).

Features

• Implemented basic support for various subsampled YUV texture formats such as NV12, which is used for video playback in some games, as well as basic support for ID3D11VideoProcessor APIs. This is needed for videos in Nier Replicant to play back (#2048), and may also be required for Contra: Rogue Corps (#1676). Note that Nier videos currently do not work with Proton for other reasons.
• Implemented Conservative Rasterization for supported GPUs, which allows enabling the Nvidia ShadowLibs option in Final Fantasy XV and possibly similar options in other games.
• Reduced presentation latency by up to one frame under some circumstances. This may help with games that are limited by vertical synchronization, DXGI frame latency settings, or external frame limiters that operate on vkAcquireNextImageKHR (PR #2075).
• Added a frame rate limiter. This is mostly intended as a workaround for games that do not work correctly at high frame rates, but can also be controlled with an environment variable. Check the README for detais.

Device selection

Software-only Vulkan implementations such as Lavapipe are no longer reported to the application as long as there is a Vulkan-capable GPU present on the system. This should fix issues where games try using Lavapipe over a proper driver on some setups with recent Mesa versions and then crash due to hitting an unsupported texture format.

Lavapipe can now be used with DXVK by manually setting the VK_ICD_FILENAMES environment variable. While some of DXVK's feature requirements have been lifted in order to allow it to run, note that limitations of this driver may still cause some games to crash or render incorrectly, while others (such as The Witcher 3) were tested successfully.

Bug fixes and Improvements

• Improved texture and buffer uploads in D3D9.
• Fixed the Origin overlay not showing up when using DXVK's DXGI implementation (#1996).
• Disabled Wine Gecko/Mono installers showing up when using install script.
• Disabled a workaround to reduce the amount of random crashes on Nvidia drivers since the underlying driver issue was fixed in the 465.xx releases (#1963), which may improve performance in some games.
• Fixed precision issues in shaders that do not have the refactoringAllowed flag set.
• Fixed some potential issues around image clears that could lead to artifacting or broken rendering.
• Fixed an issue where games with upper-case file extensions may create duplicate logs or cache files (#2079).
• Fixed monitor layout issues when restoring display modes on multi-monitor setup (#2064).
• Fixed a bug in D3D9 where child windows did not have their positions converted relative to their parents (#1958).
• Removed workarounds specific to RADV with the LLVM shader compiler. Please use the ACO backend instead (default since Mesa 20.2).
• Further reduced the size of state cache files. State caches from previous DXVK versions will be converted automatically.
• Debugging symbols now work in GDB with wine-reload (4kb file alignment)
• Misc. vector/matrix math fixes and optimizations in D3D9.
• Atelier Mysterious Trilogy Deluxe Pack, Dal Segno and Nights of Azure: Added the usual white screen workaround (#2035, #2022, #2044).
• Days Gone: Implemented missing DXGI frame statistics functions in order to fix very low frame rates (#2065).
• Demon Stone: Work around the game breaking at >60fps (#2103).
• Dragon Quest Builder 2: Fixed an issue where the game would immediately run out of system memory (PR #1995).
• Final Fantasy XIII, Spec Ops: The Line: Fixed a bug with some postprocessing effects on NVIDIA.
• GTA IV re-release: Work around incorrect VRAM amounts being shown when nvapi and atidlxx libraries are not present as it assumes all GPUs to be Intel IGPs with unified memory in that case.
• Halo 2: Fixed fog rendering issues (#2059).
• Kohan II: Fixed out-of-memory crash on startup (#2030).
• Nier Replicant: Enabled 60 FPS limit to work around issues with the game running too fast, and enforced full-rate vertical synchronization in order to work around related issues with the game sometimes being stuck at weird frame rates. Note that AMD RX 5000 and 6000 series GPUs may need to be put into high performance mode manually in order to fix performance issues caused by aggressive power management.
• Second Sight: Fixed missing UI (#2056).
• TrackMania Forever: Fixed rendering issues introduced in DXVK 1.8.

Bug fixes and Improvements

• Fixed a regression that would cause a number of D3D9 games to crash when changing the resolution or during startup.
• Fixed a regression causing black textures in some D3D9 games (#1947)
• Improved performance in many D3D9 games when using MSAA on RADV.
• Improved presentation logic for MSAA swap chains, which are common in older D3D9 games.
• Mafia II: Work around shadows being broken when the game thinks it's running on an AMD GPU.
• Warhammer Online: Work around the game trying to use unsupported image formats. (#1296)

Github actions

Support for automated builds of the current master branch as well as pull requests has been added. Builds can be found here.

Bug Fixes and Improvements

• Fixed some build system warnings with newer Meson versions.
• CPU-based Vulkan implementations such as Lavapipe will now always be enumerated last. This should avoid issues on systems without a dedicated GPU where games could potentially default to a CPU rasterizer.

• D3D9: Improved performance of texture uploads and occlusion queries in some cases.
• D3D9: Fixed an issue where supported back buffer formats would be reported incorrectly.
• DXGI: Enabled multi-monitor support. This requires a relatively recent Wine version with XRandR 1.4 support to work correctly.
• D3D11: Fixed a number of reference counting issues that could potentially lead to stability issues (PR #1887, PR ##1888).
• D3D11: Improved correctness of NaN handling in shaders with VK_KHR_shader_float_controls, and removed most app workarounds setting d3d11.enableRtOutputNanFixup.
• Enabled d3d11.enableRtOutputNanFixup by default on older RADV versions.
• Enabled d3d11.invariantPosition option by default to fix common Z-fighting issues, especially on RDNA2 GPUs.
• Atelier Ryza 2: Added workaround for video playback breaking D3D11 rendering, like in other games of the series.
• Battle Engine Aquila: Fixed broken textures (PR #1759).
• Dark Messiah of Might & Magic: Work around out-of-memory issues on startup.
• Everquest: Work around performance issues.
• F1 2018/2020: Work around broken compute shaders causing artifacts on AMD drivers, similar to F1 2019 (#1897).

• Mega Man Legacy Collection 2: Fixed rendering issues (#1922).
• Nioh 2: Work around black screen issues.
• Tomb Raider Legend: Work around performance issues (#1685).

Bug fixes and Improvements

• Added support for new DXGI interfaces introduced in Windows 10 version 1809.
• Added an option to scale the HUD on high-DPI displays. Refer to the README for details. (#771)
• Changed generated D3D11 shader code to allow drivers to optimize away texture operations in case no texture is bound.
• Fixed some old D3D9 games crashing on RADV due to invalid shader code.
• Fixed Vulkan validation errors when the HUD is active.
• Optimized away redundant render target clears in some games to potentially increase performance.
• Indirect draw batching can now work with arbitrary strides. This may slightly reduce the draw call count in Trine 4.
• EverQuest 2 Fixed broken cloth rendering on Nvidia. (#1832)
• Trine 4: Fixed rendering issues that would occur on some Nvidia GPUs as well as on RADV. (#1816)

Note: Build requirements have changed to MinGW 8.0 since new headers are required for the DXGI changes. Building on older versions will fail with messages about IDXGIFactory7 not being declared. Do not confuse the MinGW version with the GCC version provided by MinGW.

Bug fixes and Improvements

Compatibility notes

VK_EXT_transform_feedback is now a hard requirement for D3D10 and D3D11. This extension is supported by all Nvidia and Mesa drivers released in early 2019 or later, as well as recent AMDVLK releases and the proprietary AMD driver.

New Vulkan extensions

On supported drivers, the following extensions are now used:

• VK_EXT_custom_border_color is now used to support for arbitrary sampler border colors, which fixes issues in many Direct3D 9 games including Crysis and Halo 2 Vista (#1612).
• VK_EXT_robustness2 is used to handle out-of-bounds access to resources the same way as D3D11 does.

Wine 5.8 is needed for winevulkan support, as well as the following drivers:

• AMD, Intel: Mesa 20.2 (current development version)
• Nvidia: 440.66.12 (Vulkan developer beta)

Bug fixes and Improvements

• Optimized render target clears and barriers, which may slightly improve GPU-bound performance in a number of games.
• On drivers that do not support a dedicated transfer queue (primarily RADV), the compute queue will now be used for asynchronous resource uploads in D3D11 games.
• Implemented some DXGI 1.6 functionality for future versions of World of Warcraft.
• Reduced memory usage especially in D3D9, which may help with out-of-memory errors in certain games such as Toxikk. Note that this is not a solution for the general 32-bit address space problem (#1318).
• Fixed Vulkan validation errors in Cloudpunk and other games using buffer resources incorrectly.
• Fixed build on GCC 10.1 (#1620).
• Fixed various D3D9 issues.
• Reworked the dxgi.tearFree option, see PR #1606 for details.
• Fallout New Vegas: Fixed white pixel artifacts
• Freelancer: Fixed texturing issues (#1603).
• GTA IV: Fixed HUD rendering issues (#1608, PR #1626).

Build system changes

Support for winelib builds was dropped, due to maintenance issues and incompatibility with some distributions (see #1584). This makes MinGW a hard requirement for building DXVK.

Please note that mingw-w64-binutils 2.34 currently leads to broken builds; see #1625 for details and a fix for the issue.
