| | `WINE_FULLSCREEN_INTEGER_SCALING` | Enable integer scaling mode, to give sharp pixels when upscaling. |
| `cmdlineappend:` | | 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. |
| `nowritewatch` | `PROTON_NO_WRITE_WATCH` | Disable support for memory write watches in ntdll. This is a very dangerous hack and should only be applied if you have verified that the game can operate without write watches. This improves performance for some very specific games (e.g. CoreRT-based games). |
| `nosteamffmpeg` | `PROTON_NO_STEAM_FFMPEG` | Ignore ffmpeg that ships with Steam. Some videos may not play. |
| `seccomp` | `PROTON_USE_SECCOMP` | **Note: Obsoleted in Proton 5.13.** In older versions, enable seccomp-bpf filter to emulate native syscalls, required for some DRM protections to work. |
| `d9vk` | `PROTON_USE_D9VK` | **Note: Obsoleted in Proton 5.0.** In older versions, use Vulkan-based DXVK instead of OpenGL-based wined3d for d3d9. |
