Added support for the validator in order to make debugging easier, as well as the optimizer, which may help Nvidia users run DXVK.

# DXVK
|
|
|
|
A Vulkan-based compatibility layer for Direct3D 11 which allows running 3D applications on Linux using Wine.
|
|
|
|
For the current status of the project, please refer to the [project wiki](https://github.com/doitsujin/dxvk/wiki).
|
|
|
|
For binary releases, see the [releases](https://github.com/doitsujin/dxvk/releases) page.
|
|
|
|
## Build instructions
|
|
|
|
### Requirements:
|
|
- [wine-vulkan](https://github.com/roderickc/wine-vulkan) for Vulkan support
|
|
- [Meson](http://mesonbuild.com/) build system (at least 0.43)
|
|
- [MinGW64](http://mingw-w64.org/) compiler and headers (requires threading support)
|
|
- [glslang](https://github.com/KhronosGroup/glslang) front end and validator
|
|
|
|
### Building DLLs
|
|
Inside the dxvk directory, run:
|
|
```
|
|
# 64-bit build. For 32-bit builds, replace
|
|
# build-win64.txt with build-win32.txt
|
|
meson --cross-file build-win64.txt build.w64
|
|
cd build.w64
|
|
meson configure -Dprefix=/your/dxvk/directory/
|
|
# for an optimized release build:
|
|
meson configure -Dbuildtype=release
|
|
ninja
|
|
ninja install
|
|
```
|
|
|
|
The two libraries `dxgi.dll` and `d3d11.dll`as well as some demo executables will be located in `/your/dxvk/directory/bin`.
|
|
|
|
## How to use
|
|
In order to set up a wine prefix to use DXVK instead of wined3d globally, run:
|
|
```
|
|
cd /your/dxvk/directory/bin
|
|
WINEPREFIX=/your/wineprefix bash setup_dxvk.sh
|
|
```
|
|
|
|
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).
|
|
|
|
### Notes on Vulkan drivers
|
|
Before reporting an issue, please check the [Wiki](https://github.com/doitsujin/dxvk/wiki/Driver-support) page on the current driver status.
|
|
|
|
### 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.**
|
|
|
|
### Environment variables
|
|
The behaviour of DXVK can be modified with environment variables.
|
|
|
|
- `DXVK_DEBUG_LAYERS=1` Enables Vulkan debug layers. Highly recommended for troubleshooting and debugging purposes.
|
|
- `DXVK_SHADER_DUMP_PATH=directory` Writes all DXBC and SPIR-V shaders to the given directory
|
|
- `DXVK_SHADER_READ_PATH=directory` Reads SPIR-V shaders from the given directory rather than using the shader compiler.
|
|
- `DXVK_SHADER_VALIDATE=1` Enables SPIR-V shader validation. Useful for debugging purposes.
|
|
- `DXVK_SHADER_OPTIMIZE=1` Enables SPIR-V shader optimization. Experimental, use with care.
|
|
- `DXVK_LOG_LEVEL=error|warn|info|debug|trace` Controls message logging.
|
|
- `DXVK_HUD=1` Enables the HUD
|
|
|
|
## Samples and executables
|
|
In addition to the DLLs, the following standalone programs are included in the project.
|
|
Most of them require a native `d3dcompiler_47.dll`, which you can retrieve from your
|
|
Windows installation in case you have one.
|
|
|
|
- `d3d11-compute`: Runs a simple compute shader demo.
|
|
- `d3d11-triangle`: Renders a bunch of triangles using D3D11.
|
|
- `dxgi-factory`: Enumerates DXGI adapters and outputs for debugging purposes.
|
|
- `dxbc-compiler`: Compiles a DXBC shader to SPIR-V.
|
|
- `dxbc-disasm`: Disassembles a DXBC shader.
|
|
- `hlsl-compiler`: Compiles a HLSL shader to DXBC.
|
|
|
|
## 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, 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++
|
|
```
