Steam Deck

Table of Contents

Usage

It is intended to install and configure games from desktop mode only. Running Heroic itself through Game Mode is not supported and you may encounter issues doing so.

The proper way to use Heroic with the Steam Deck is to open Heroic in desktop mode, install and update games from there. You may need to play games at least once in desk top mode to confirm that they are functioning properly and in the case where a game requires user interaction on first launch, such as associating your Epic account with the game via a web browser pop up.

Once a game is installed, you can add it to steam through the 3 dot menu on the game page, or by selecting "auto add to steam" from the heroic settings on the side bar.

HDR

Flatpak

Installing Gamescope

The Heroic Flatpak requires the Gamescope Flatpak to enable HDR. However, the Flatpak Gamescope version must match the version of the natively installed Gamescope. As of December 11th, 2024, the Steam Deck Gamescope is on version 3.15.14. The natively installed Gamescope is close enough to the latest version of the Flatpak meaning the only step required to enable HDR is to install the Flatpak Gamescope.

To enable HDR with the Flatpak version of Heroic, follow the below steps.

  1. Switch to Desktop Mode.
  2. Open Konsole.
  3. Type the following command and press enter:
    • flatpak install org.freedesktop.Platform.VulkanLayer.gamescope
    • Locate runtime/org.freedesktop.Platform.VulkanLayer.gamescope/x86_64/24.08 in the list and confirm your selection by typing the respective number. For example, if it is the third item in the list, type 3 and press enter.
  4. The Flatpak Gamescope will now be installed and HDR will now work in Game Mode.

Optional: Freezing Gamescope Updates

If the Gamescope Flatpak updates and is no longer in sync with the natively installed Gamescope, HDR may stop working. As an optional step, you may mask the Gamescope Flatpak in order to "freeze" its updates.

  1. Switch to Desktop Mode.
  2. Open Konsole
  3. Type the following command and press enter:
    • sudo flatpak mask org.freedesktop.Platform.VulkanLayer.gamescope
  4. The Gamescope Flatpak will now be masked and its updates will be "frozen".

To unmask the Gamescope Flatpak, use the following command:

sudo flatpak --remove mask org.freedesktop.Platform.VulkanLayer.gamescope

Validating Gamescope's Version

  1. Switch to Desktop Mode.
  2. Open Konsole.
  3. Type the following command and press enter:
    • gamescope --version
    • As of December 11th, 2024, the Gamescope version currently installed should be 3.15.14, note this down for the next step.
  4. Open https://flathub.org/apps/org.freedesktop.Platform.VulkanLayer.gamescope in a web browser of your choice.
  5. Locate the version number at the top of the page and compare it to the version number you gathered in Step 3.
    • As of December 11th, 2024, the version gathered in Step 3 should be 3.15.14 and the version on the link above should be 3.14.24. These versions are close enough for the Gamescope Flatpak to work through the Heroic Games Launcher.

AppImage

HDR will work out of the box with the AppImage.

Common Issues

Mangohud does not work

Check if you have installed the Flatpak version of Mangodhud: flatpak install org.freedesktop.Platform.VulkanLayer.MangoHud

Gamescope not available

Check if you have installed the Flatpak version of Gamescope: flatpak install org.freedesktop.Platform.VulkanLayer.gamescope

If you are on a Steam Deck, the Flatpak version of Gamescope must match the natively installed version. If these versions do not match, you may experience increased crashing in other Flatpaks.
