 |                       | <tt>PROTON_DEBUG_DIR</tt>      | Root directory for the Proton debug scripts, `/tmp` by default. |

-| <tt>d9vk</tt>         | <tt>PROTON_USE_D9VK</tt>       | Use Vulkan-based d9vk instead of OpenGL-based wined3d for d3d9. |

 | <tt>nod3d10</tt>      | <tt>PROTON_NO_D3D10</tt>       | Disable <tt>d3d10.dll</tt> and <tt>dxgi.dll</tt>, for d3d10 games which can fall back to and run better with d3d9. |

 | <tt>nofsync</tt>      | <tt>PROTON_NO_FSYNC</tt>       | Do not use futex-based in-process synchronization primitives. (Automatically disabled on systems with no `FUTEX_WAIT_MULTIPLE` support.) |
 | <tt>forcelgadd</tt>   | <tt>PROTON_FORCE_LARGE_ADDRESS_AWARE</tt> | Force Wine to enable the LARGE_ADDRESS_AWARE flag for all executables. |
 | <tt>oldglstr</tt>     | <tt>PROTON_OLD_GL_STRING</tt>  | Set some driver overrides to limit the length of the GL extension string, for old games that crash on very long extension strings. |
 |                       | <tt>WINE_FULLSCREEN_INTEGER_SCALING</tt> | Enable integer scaling mode, to give sharp pixels when upscaling. |
+| <tt>d9vk</tt>         | <tt>PROTON_USE_D9VK</tt>       | **Note: Obsoleted in Proton 5.0.** In older versions, use Vulkan-based DXVK instead of OpenGL-based wined3d for d3d9. |
