### Environment variables
The behaviour of DXVK can be modified with environment variables.
- `DXVK_SHADER_DUMP_PATH=directory` Writes all DXBC and SPIR-V shaders to `directory`
- `DXVK_SHADER_DUMP_PATH=directory` Writes all DXBC and SPIR-V shaders to the given directory
- `DXVK_SHADER_READS_PATH=directory` Reads SPIR-V shaders from the given directory instead of compiling the DXBC shader.
- `DXVK_DEBUG_LAYERS=1` Enables Vulkan debug layers. Highly recommended for troubleshooting and debugging purposes.
