This is one is very confusing, which probably speaks to the current UI in Heroic. I just want to say, run this game in gamescope, so I can use HDR.

I have the latest version of Heroic, installed via Flatpak as the devs recommend. If I go to configure the game in the UI it has an entire settings page dedicated to Gamescope but nothing that says “enable gamescope”.

Anyone get this working?

    It’s weird. You have to check the “enable upscaling” box, then set “Game Width” and “Game Height”, but leave “Upscale {Width,Height}” empty.

      I wouldn’t have thought to try that, thanks. Can confirm it looks like it is running Gamescope now. However I am still not getting an HDR switch in Alan Wake 2.

      Getting the following errors:

      “CreateSwapchainKHR: Creating swapchain for non-Gamescope swapchain. Hooking has failed somewhere! You may have a bad Vulkan layer interfering. Press OK to try to power through this error, or Cancel to stop.”

      “QueuePresentKHR: Attempting to present to a non-hooked swapchain. Hooking has failed somewhere! You may have a bad Vulkan layer interfering. Press OK to try to power through this error, or Cancel to stop.”

        I don’t use HDR so I’m of limited help there. You’ll have to pass those options using the “Additional Options” field. Run gamescope --help and look for relevant options. Also remember that HDR support on Linux is still primitive.

          Got it working, added to -f --hdr-enabled to the Additional Options section under the upscale options in the Gamescope tab. Note that you need to have upscape ticked even with additional options added.

          Unfortunately it looks washed out and awful.

            Unfortunately it looks washed out and awful.

            That tends to happen when HDR is not supported somewhere in the pipeline from the game renderer to the monitor. It’s not a standard Wayland feature, most compositors only have experimental or WIP implementations, and X11 is never getting it. You’ll also have to use the perfect settings to make it look any good.

            When I said “primitive”, I really meant “sharpened stick” primitive.

            It could also be Flatpak’s sandboxing messing it up, so maybe try running the game through Lutris. The existing installation should work fine.

            gamescope is a mess inside of Flatpak as of right now. Some issue with using Proton inside of gamescope inside of Flatpak.

            I played Alan Wake 2 using the native Heroic version and native gamescope.

            The gamescope version still needs to be pretty recent. After starting the game make sure its brightness does not change when you play with the SDR intensity slider. If it does, it’s not using HDR.

            Also, Alan Wake is a pretty bleak looking game in general so you might want to pop some flares to bring some color for testing.

              Ah - thanks for the heads up about the Flatpak version. I have everything running in Flatpak, Steam as well, so that may be why I’ve had zero luck with HDR.
