| <tt>noxim</tt> | <tt>PROTON_NO_XIM</tt> | Enabled by default. Do not attempt to use XIM (X Input Methods) support. XIM support is known to cause crashes with libx11 older than version 1.7. |
| <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>heapdelayfree</tt>| <tt>PROTON_HEAP_DELAY_FREE</tt>| Delay freeing some memory, to work around application use-after-free bugs. |
| <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. |
| <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. |
