| <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. |
| | <tt>WINE_FULLSCREEN_INTEGER_SCALING</tt> | Enable integer scaling mode, to give sharp pixels when upscaling. |
| <tt>cmdlineappend:</tt>| | Append the string after the colon as an argument to the game command. May be specified more than once. Escape commas and backslashes with a backslash. |
| <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. |
