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.

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.

I was not able to get HDR working in Flatpak, neither through Wine Wayland nor through gamescope.

So if you manage to do it let me know. :D

I got it to engage, the game thinks it’s running in HDR but it just looks really bad

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.

I believe only plasma 6 has support for HDR, and it requires additional config to enable it with games. Otherwise, it will look washed out as you found.

Alternatively, you can use gamescope-session which is basically running gamescope as a standalone like the steam deck.

Yeah I was running the game under Plasma 6 with HDR enabled and inside a game scope container.

Sounds like there are some issues with Flatpak and HDR so that may be what I am hitting.

What additional configuration are you referring to?

Looking here, you might not need it anymore: zamundaaa.github.io/…/more-hdr-and-color.html

But make sure gamescope is a recent version.

Since the last two posts about this topic (part one, part two) there has been some more progress, so let’s take a look.
