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. 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.”
