 | <tt>noesync</tt>      | <tt>PROTON_NO_ESYNC</tt>       | Do not use eventfd-based in-process synchronization primitives. |
 | <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>nativevulkanloader</tt> |                          | Use the Vulkan loader shipped with the game instead of Proton's built-in Vulkan loader. This breaks VR support, but is required by a few games. |
 | <tt>forcelgadd</tt>   | <tt>PROTON_FORCE_LARGE_ADDRESS_AWARE</tt> | Force Wine to enable the LARGE_ADDRESS_AWARE flag for all executables. Enabled by default. |
 | <tt>gamedrive</tt>    | <tt>PROTON_SET_GAME_DRIVE</tt> | Create an S: drive which points to the Steam Library which contains the game. |
 | <tt>noforcelgadd</tt> |                                | Disable forcelgadd. If both this and `forcelgadd` are set, enabled wins. |
