How the heck do I get gamescope working with Heroic Games Launcher? (self.linux_gaming)

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?

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.

Edit: Just a quick note for folks this later on - it does indeed seem Flatpak related, or at the very least I got similar results under the Steam flatpak trying to run game in HDR. I ended installing the native package Steam and lo and behold, HDR no longer looks as washed out, though it still looks a little off compared to Windows. Those swapchains errors I was getting also vanish.

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
