How the heck do I get gamescope working with Heroic Games Launcher? - Lemmy.World

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?

You have to install the org.freedesktop.Platform.VulkanLayer.gamescope flatpak package. You’ll be given a choice of which version: HGL needs 23.08.

Keep in mind that Flatpak apps are sandboxed and don’t have full access to the system, including other installed applications and libraries.

Thanks! I actually have that installed already.

How do I tell Heroic to launch the game under gamescope vs the normal compositor?

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. However I am still not getting an HDR switch in Alan Wake 2.

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.
