Proton

Drop’s Proton configuration depends on:

• UMU launcher (more specifically the umu-run binary)
• another application to download and manage Proton versions

Installing UMU launcher

Install UMU launcher through their own guide on their GitHub repo. It covers packaging for a variety of distro. If you’re not covered, give it a Google search, or open an issue on GitHub or Discord and we’ll try to help you.

To check it’s installed, try running umu-run from your terminal.

Note

If you’re using Distrobox, it needs to be installed within the container.

Downloading other Proton versions

You can download other Proton versions from a variety of sources:

• Directly from the project, typically in a GitHub release
• Through Steam, which downloads official Proton versions
• 3rd-party application

For the 3rd-party application, we recommend ProtonUp-Qt, an open-source GUI application that supports quite a few different versions of Proton.

Detecting Proton versions

Drop searches the following places for Proton versions:

• /usr/share/steam/compatibilitytools.d/
• ~/.steam/root/compatibilitytools.d/

Most applications support reading and writing to these directories for Proton versions, as they’re Steam directories.

Drop can also pick up other Proton versions, if you manually add them.

Note

To be discovered by Drop, the folder you provide, or any folder in one of the above directories must:

• have the proton binary
• have a compatibilitytool.vdf file

Using Proton versions

Caution

To launch any Windows game, you must first set a default Proton version.

Drop uses a global default Proton version to launch games by default. You can override this in a game’s options.
