Q & A

What is the Gamecope launcher and how does it function?

The Gamecope launcher is a tool designed to provide a seamless gaming experience by launching Steam and running it in an isolated 'Gamecope' session. It enables users to play Steam games within this environment, using keybindings (Super Shift S to launch and Super Shift R to return to the desktop).

What hardware configurations are supported by Gamecope?

Gamecope works well with AMD and Nvidia hardware. It is not compatible with Intel-based systems, whether using integrated graphics (iGPU) or discrete Intel GPUs. There are separate configurations available for Intel systems, but they require manual installation and are more complex.

Are there any resolution limitations when using Nvidia GPUs with Gamecope?

Yes, with Nvidia GPUs, the maximum supported resolution is 2560x1440p. Any attempts to go above this resolution can cause issues and graphical glitches.

What is Proton GE and how does it integrate with Gamecope?

Proton GE (Glorious Eggroll) is a compatibility layer that helps run Windows-based games on Linux. Gamecope integrates Proton GE to ensure smooth game performance by switching games to Proton GE mode directly from Steam, avoiding additional external setup steps.

What should users do if they encounter issues with Gamecope on Nvidia systems?

Users with Nvidia GPUs must add a specific command line ('Nvidia DRM mod set = 1') to enable proper functionality. A reboot is required after this step. Additionally, Nvidia users are advised to adjust settings to avoid exceeding the 2560x1440 resolution limit.

How does the installation process of Gamecope work?

The installation involves downloading a script, granting execution permissions, and running it through a terminal. The script installs necessary components such as Vulcan, Proton GE, and the Gamecope launcher. It also sets up configurations for Steam and compatibility layers.

Does Gamecope automatically recognize external storage for Steam games?

Yes, Gamecope automatically detects and integrates external Steam libraries from USB drives. Users don't need to manually attach the external drive for game access—Gamecope scans for it and adds the games to the launcher automatically.

How does the performance of games on Gamecope compare to running them on Steam Deck?

Games on Gamecope perform similarly to running on Steam Deck, as it uses a Steam-based back end. If a game runs well on a Steam Deck, it should also run well on Gamecope. The system is optimized for AMD hardware but also works with Nvidia, with some limitations on resolution and settings.

What steps are needed to configure a game for optimal performance in Gamecope?

To configure a game in Gamecope, users need to ensure that compatibility settings are set to Proton GE. They should also disable the pre-shader cache and ensure that the game's frame rate limit is removed for smoother gameplay. Additionally, enabling the performance overlay can help track game performance.

Can users modify or improve Gamecope by adding custom plugins?

Yes, users can extend Gamecope's functionality by adding plugins. For example, Decki Loader and a GeForce Now plugin can be installed for additional features. The launcher is also open-source, allowing users to modify and improve it as needed.
