Driver support

The Vulkan extension VK_KHR_maintenance5 is now required. DXVK has been relying on guarantees made by this extension since version 2.5, so in order to remove some maintenance burden, fallbacks that would allow older drivers to run were now removed.

Please check the driver support page on the Wiki for details.

Note: These changes will primarily affect Windows users on AMD Polaris and Vega GPUs, for which AMD has effectively discontinued driver support. On Linux, these older GPUs will keep working on RADV when using Mesa 25.0 or newer.

Due to a growing number of compatibility issues with the AMD Windows driver in general, supporting it is no longer a priority.

Binding model changes

Descriptor management was largely rewritten and modernized. On newer AMD and Nvidia cards, VK_EXT_descriptor_buffer is now used by default, which significantly reduces CPU overhead compared to the legacy binding model and may thus improve CPU-bound performance in games such as Final Fantasy XIV, God of War, Metaphor: ReFantazio, Watch Dogs 2 and others.

This feature remains disabled on older GPUs due to severe performance regressions in some cases, specifically on Nvidia Pascal or older, as well as AMD RDNA2 or older when using AMDVLK or the AMD Windows driver. RADV is unaffected by these issues.

Note: A small hit to GPU-bound performance is expected in some cases, in exchange for more consistent overall performance. Users can override the default behaviour with the dxvk.enableDescriptorBuffer option. Enabling Resizeable BAR on supported systems is strongly recommended.

Memory management

Memory defragmentation is now enabled by default on Intel Battlemage and Lunar Lake GPUs. On older Intel GPUs, this feature remains disabled as it may cause rendering issues for unknown reasons, see #4395.

On discrete GPUs, DXVK will now enforce the driver-reported VRAM budget as much as possible, and dynamically evict unused resources to system memory when under memory pressure. This should improve performance in many Unity Engine titles on VRAM-constrained systems, and may allow for higher texture quality settings to be used in some games. Temporary slowdowns and stutters are still expected when exceeding VRAM capacity.

Note: This feature currently does not work as intended on AMD GPUs due to kernel driver issues.

Legacy feature removal

The state cache was introduced in Version 0.80 to reduce shader compilation stutter, and has been largely unused since the introduction of VK_EXT_graphics_pipeline_library in DXVK 2.0. In order to reduce maintenance burden, particularly with pipeline-related changes in this release, this legacy feature was now removed.

Additionally, the d3d9.forceSwapchainMSAA option was removed. This feature was not really useful since most games either use additional render targets or provide a built-in MSAA option themselves anyway. For games that do not provide built-in MSAA, users are encouraged to use Gamescope to run these games with a higher render resolution instead.

Bug fixes and Improvements

• Added support for planar video output views. (PR #4872).
  This is required for video playback in JR EAST Train Simulator.
• D3D11 shaders will now zero-initialize all variables and groupshared memory by default in order to work around game bugs resulting in undefined behaviour. The d3d11.zeroWorkgroupMemory option was removed accordingly.
• Optimized D3D9 StretchRect in certain multisample resolve cases encountered in Source Engine. (PR #5023)
• Fixed an instance of invalid Vulkan usage in Modulus, and possibly other Unity Engine games that use the D3D11 video API.
• Implemented support for the ID3DDestructionNotifier interface.
• Vulkan devices that lack the required feature support to run DXVK will no longer be listed as DXGI / D3D9 adapters. This may fix crashes in case an outdated graphics driver or an unsupported integrated GPU are present on the system.
• Trying to build DXVK in a MinGW environment with AVX enabled will now result in a compile-time error.
  We cannot support AVX builds due to toolchain issues, nor is it expected to be beneficial.

• Test Drive Unlimited 2: Worked around alt-tab issue causing input loss. (PR #5057)
• Wargame: European Escalation: Worked around gamma issue when the game detects an Nvidia GPU. (PR #5055)

This is a maintenance release intended to fix some bugs and regressions from version 2.6.1. It is not based on latest development code and does not use or require any new Vulkan features.

Bug fixes and Improvements

• Added DXVK_FILTER_DEVICE_UUID environment variable to filter devices by their reported driver UUID. (PR #4956)
  This may be useful on setups with multiple GPUs of the same model.
• Improved vendor ID override logic for D3D9 and added d3d9.hide{Amd,Intel,Nvidia}Gpu configuration options to improve the out-of-the-box experience in games that refuse to run on Intel GPUs, or only run with significantly reduced graphics features. (PR #4869)
• Improved WSI backend selection in dxvk-native.

D3D10 / D3D11

Nvidia Reflex support

When running Proton Experimental and an Nvidia driver with VK_NV_low_latency2 support, Reflex can now be enabled in D3D11 games that support this feature. This includes God of War, Overwatch 2, Quake Champions and some others. Approximate input latency can be displayed in these games by setting DXVK_HUD=latency.

Note: Reflex does not work in most Unreal Engine 4 games in D3D11 mode since LatencySleep and other related functions never get called. This cannot be worked around inside DXVK; prefer using D3D12 for affected games.

Bug fixes and Improvements

• Worked around a common game bug that would cause garbled output on Nvidia when using MSAA. (#4480, PR #4731)
  This affects games such as Assassin's Creed 3 / Black Flag, Watch Dogs, Stalker: Clear Sky, and others.
  Note: This may have a small impact on performance and memory usage in affected games, including on AMD GPUs, where this issue did not manifest in rendering issues due to hardware details.
• Potentially improved GPU-bound performance in games that use NVAPI UAVOverlap feature, such as Baldurs Gate 3.
  While this feature was supported before, our previous implementation was too conservative. (PR #4691)
  Note: Like other vendor extensions, this does not work on Windows.

D3D8 / D3D9

• Fixed a race condition that could lead to crashes in games doing multi-threaded asset loading. (#4613, PR #4646)
• Fixed various issues that would occur when disabling shader support via the d3d9.shaderModel option. (#4625, PR #4629)

General Improvements

• Reworked Vulkan swapchain implementation to be more robust. (PR #4609)
• Improved efficiency of multisample resolves on tiling GPUs.
• Fixed a regression introduced in DXVK 2.5 that would cause memory allocation errors on certain unified memory setups, including the Qualcomm proprietary driver.
  Note: This does not mean that DXVK will officially support Android, or proprietary mobile drivers.
• Fixed a crash if an application unloads the SetupAPI DLL. This issue affected various AdvHD-based visual novels. (#4662, PR #4668)
• Fixed an issue where software rasterizers such as Lavapipe would not be considered when setting DXVK_FILTER_DEVICE_NAME. (PR #4716)
• Resource initialization is now always performed on the asynchronous transfer queue if possible, and no longer uses additional memory on drivers that support Vulkan sparse residency features. This may save up to 64 MiB of VRAM in some games.

• Worked around potential 32-bit crashes caused by stack alignment issues in GCC-compiled binaries. (PR #4627, PR #4633)

The Developer guidelines wiki page was updated to reflect current implementation details.

Windows changes

In order to address feedback regarding issues with variable refresh rate displays, performance and HDR, exclusive full-screen mode was reintroduced as an option. It remains disabled by default, but users can enable it by setting dxvk.allowFse = True in the configuration file.

As usual, this option has no effect on non-Windows platforms.

Bug fixes and Improvements

• Fixed a regression that would cause severe rendering issues in many D3D8 and D3D9 games that use fixed-function rendering. (PR #4533)
• Fixed invalid shader code generation for certain rare texture operations in D3D11.

• The Hurricane of the Varstray -Collateral hazard-: Enabled 60 FPS limit to work around game issues when running in windowed mode. (#4568, PR #4573)

Windows changes

On Windows, if VK_EXT_fullscreen_exclusive is supported, DXVK will now always try to disable exclusive fullscreen in an attempt to work around common alt-tab issues, as well as issues with numerous games that mix D3D9 with GDI user interfaces. Whether this is honored is up to the graphics driver. (#4465, PR #4485)

Previously, this was only done for D3D9 applications that explicitly enabled support for GDI dialog boxes in fullscreen mode. The d3d9.enableDialogMode configuration option to control that behaviour was removed accordingly.

Note: This change may affect input latency and/or performance, depending on the exact implementation of Vulkan swap chains in the graphics driver. It does not affect Linux systems in any way since the concept of exclusive fullscreen, and thus any problems associated with it, do not exist there.

Bug fixes and Improvements

• Added an implementation of D3D9 shader validation interfaces. This is needed for The Void and used in several other D3D9 games. (PR #4398)
• Fixed behaviour when D3D9 applications use incorrect texture types as seen in Alpha Protocol. (PR #4513)
• If VK_KHR_maintenance5 is supported, DXVK will now use VK_FORMAT_A8_UNORM to implement the corresponding D3D11 format. This fixes warnings in various games, as well as rendering issues in TopSpin 2K25 (#4514).
• Optimized behaviour of disabled clip planes for D3D9 games. (PR #4508)
• Fixed an issue where the DXVK_CONFIG environment variable was not applied correctly under specific circumstances.

• Fixed some build issues with dxvk-native. (PR #4446)
• Fixed some build issues with recent versions of clang. (#4467)
• GTA Trilogy Definitive Edition: Work around a crash when HDR is enabled. (PR #4450)
  Note: Since these games use Unreal Engine 4, HDR is unsupported in D3D11 mode.

Memory managment

Resource and memory management were completely rewritten in order to use allocated video memory more efficiently:

• Reduced fragmentation may reduce peak memory usage in games such as God of War by up to 1 GiB in extreme cases.
• Memory defragmentation is now performed periodically to return some unused memory back to the system.
  The goal is not to reduce VRAM usage at all costs; instead this is done conservatively if the system is under memory pressure, or if a significant amount of allocated memory is unused. Keeping some unused memory is useful to quickly service subsequent allocations.

Note: Defragmentation is currently disabled on Intel's ANV driver, see #4434. The dxvk.enableMemoryDefrag config option can be set to enable or disable this feature via the the Configuration file.

Driver support

While technically not required, the new memory management works best on drivers that support both VK_EXT_memory_budget and VK_KHR_maintenance5. The Driver Support page was updated accordingly.

D3D8 / D3D9

Software cursor

Support for emulated cursors was implemented for the D3D9 cursor API, which allows games to set an arbitrary image as the mouse cursor. This fixes an issue in Dungeon Siege 2 (#3020) and makes the cursor appear correctly in Act of War and various older D3D8 games. (PR #4302)

Sampler pool

Unreal Engine 3 games using D3D9 have a quirk in that they pass a seemingly uninitialized value as the mipmap LOD bias. In order to avoid creating more Vulkan sampler objects than the driver supports, previous versions of DXVK would round the LOD bias to a multiple of 0.5, which could introduce visual inaccuracies. As a more correct solution, DXVK will now destroy unused Vulkan samplers on the fly and use the correct LOD bias.

Note: The aforementioned workaround was never needed or used in the D3D11 implementation, it only affected D3D9.

Bug fixes and Improvements

• On Nvidia driver version 565.57.01 and newer, strict float emulation is enabled by default for improved correctness.
  Games for which this option was already enabled may see a small performance uplift on this driver.
• Made various changes to potentially improve performace on certain mobile GPUs. (includes PR #4358)

• Tomb Raider: Legend: Fixed flickering geometry with strict float emulation. (#4319, PR #4442)
• Rayman 3: Fixed a regression that caused rendering issues. (#4422, PR #4423)

D3D11 / DXGI

Resource management changes

In order to reduce system memory pressure and improve stability in 32-bit games, creating, uploading and discarding resources is now throttled if the amount of temporary staging memory allocations exceed a certain threshold. This fixes crashes in Total War: Rome II and a number of other games. Additionally, large DYNAMIC textures commonly used for video playback will no longer use a staging buffer.

The d3d11.maxDynamicImageBufferSize and d3d11.maxImplicitDiscardSize options were removed accordingly; affected games such as Total War: Warhammer III and Ryse: Son of Rome should now perform well by default, without excessive memory usage.

Note: These changes negatively affect CPU-bound performance in a number of games, including Shadow Warrior 2.

Bug fixes and Improvements

• SEQUENTIAL swap effects are now implemented for DXGI swap chains, which allows games to read previously presented backbuffers. This fixes an issue wherein savegame thumbnails would appear black in certain visual novels. (ValveSoftware/Proton#7017)
• Devirtualized some D3D11 method calls to improve compatibility with Special K.

General improvements

• The size for memory chunks is now determined dynamically based on the amount of memory the application has already allocated.
  This should improve the out-of-the-box behaviour in various game launchers; the dxvk.maxChunkSize option was removed accordingly.
• Fixed an issue where the Vulkan swap chain would not always be recreated appropriately in a native Wayland environment. (PR #4252)
• Fixed an issue with descriptor pools growing too large on Nvidia cards in some situations. (PR #4166)
