DXVK

A Vulkan-based translation layer for Direct3D 10/11 which allows running 3D applications on Linux using Wine.

For the current status of the project, please refer to the project wiki.

How to use

In order to install a DXVK package obtained from the release page into a given wine prefix, run the following commands from within the DXVK directory:

export WINEPREFIX=/path/to/.wine-prefix
winetricks --force setup_dxvk.verb

This will copy the DLLs into the system32 and syswow64 directories of your wine prefix and set up the required DLL overrides. Pure 32-bit prefixes are also supported.

Verify that your application uses DXVK instead of wined3d by checking for the presence of the log files d3d11.log and dxgi.log in the application's directory, or by enabling the HUD (see notes below).

Build instructions

Requirements:

• wine 3.10 or newer
• Meson build system (at least version 0.43)
• MinGW64 compiler and headers (requires threading support)
• glslang compile

Building DLLs

The simple way

Inside the DXVK directory, run:

./package-release.sh master /your/target/directory --no-package

This will create a folder dxvk-master in /your/target/directory, which contains both 32-bit and 64-bit versions of DXVK, which can be set up in the same way as the release versions as noted above.

Compiling manually

# 64-bit build. For 32-bit builds, replace
# build-win64.txt with build-win32.txt
meson --cross-file build-win64.txt --prefix /your/dxvk/directory build.w64
cd build.w64
meson configure 
# for an optimized release build:
meson configure -Dbuildtype=release
ninja
ninja install

The D3D10, D3D11 and DXGI DLLs as well as a shell script to set up DXVK for a specific wine prefix will be located in /your/dxvk/directory/bin.

Notes on Vulkan drivers

Before reporting an issue, please check the Wiki page on the current driver status and make sure you run a recent enough driver version for your hardware.

Online multi-player games

Manipulation of Direct3D libraries in multi-player games may be considered cheating and can get your account banned. This may also apply to single-player games with an embedded or dedicated multiplayer portion. Use at your own risk.

HUD

The DXVK_HUD environment variable controls a HUD which can display the framerate and some stat counters. It accepts a comma-separated list of the following options:

• devinfo: Displays the name of the GPU and the driver version.
• fps: Shows the current frame rate.
• frametimes: Shows a frame time graph.
• submissions: Shows the number of command buffers submitted per frame.
• drawcalls: Shows the number of draw calls and render passes per frame.
• pipelines: Shows the total number of graphics and compute pipelines.
• memory: Shows the amount of device memory allocated and used.
• version: Shows DXVK version.

Additionally, DXVK_HUD=1 has the same effect as DXVK_HUD=devinfo,fps.

Device filter

Some applications do not provide a method to select a different GPU. In that case, DXVK can be forced to use a given device:

• DXVK_FILTER_DEVICE_NAME="Device Name" Selects devices with a matching Vulkan device name, which can be retrieved with tools such as vulkaninfo.

Note: If the device filter is configured incorrectly, it may filter out all devices and applications will be unable to create a D3D device.

State cache

DXVK caches pipeline state by default, so that shaders can be recompiled ahead of time on subsequent runs of an application, even if the driver's own shader cache got invalidated in the meantime. This cache is enabled by default, and generally reduces stuttering.

The following environment variables can be used to control the cache:

• DXVK_STATE_CACHE=0 Disables the state cache.
• DXVK_STATE_CACHE_PATH=/some/directory Specifies a directory where to put the cache files. Defaults to the current working directory of the application.

Debugging

The following environment variables can be used for debugging purposes.

• VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_standard_validation Enables Vulkan debug layers. Highly recommended for troubleshooting rendering issues and driver crashes. Requires the Vulkan SDK to be installed on the host system.
• DXVK_LOG_LEVEL=none|error|warn|info|debug Controls message logging.
• DXVK_LOG_PATH=/some/directory Changes path where log files are stored.
• DXVK_CONFIG_FILE=/xxx/dxvk.conf Sets path to the configuration file.

Troubleshooting

DXVK requires threading support from your mingw-w64 build environment. If you are missing this, you may see "error: 'mutex' is not a member of 'std'". On Debian and Ubuntu, this can usually be resolved by using the posix alternate, which supports threading. For example, choose the posix alternate from these commands (use i686 for 32-bit):

update-alternatives --config x86_64-w64-mingw32-gcc
update-alternatives --config x86_64-w64-mingw32-g++
