com.heroicgameslauncher.hgl VS com.usebottles.bottles

The link you put states that the command is heroic but that would be true only in the first two cases (RPM package from the repos or manually installed). If you installed it as a flatpak from FlatHub, e.g., the command would rather be:

The epic games launcher doesn't have linux support. Download the Heroic Games Launcher from flatpak https://flathub.org/apps/details/com.heroicgameslauncher.hgl

Thanks to the 2.5.0 release of Heroic available on Github (also available as an appimage) and Flatpak now the user has the ability to add Windows executables and installers in Heroic, and preview them in his library, here a little more information about this:

Try Heroic Games launcher, it replaces EGS and GOG launchers.

Install Heroic Games Launcher from the Discover store, it definitely seems like the best way to run Epic and GOG games: https://flathub.org/apps/details/com.heroicgameslauncher.hgl Heroic can then add shortcuts to the games you install to Steam, so you can launch them in game mode.

You could ask the maintainers of the Heroic flatpak to add gamescope as an extension, it should be fairly simple to implement and PolyMC and WarThunder are currently doing that.

You can download Heroic Games from Discover (shopping bag icon) in desktop mode (link to the flathub page: https://flathub.org/apps/details/com.heroicgameslauncher.hgl).

Not really, I just installed the Flatpak from here: https://flathub.org/apps/details/com.heroicgameslauncher.hgl

More info here: https://flathub.org/apps/details/com.usebottles.bottles

Install a Chromium-based browser (e.g. Brave) using Wine (I did it using Bottles), and you should be able to stream in 1080p.

GNU Bottles

Or you can use it as a Runner in Bottles and avoid all the hassle.

If it's a Windows game, maybe you can run it by Bottles.

For those using Bottles instead of Lutris, the installer for EA App there also Just Works™. Just last month I was playing Star Wars Squadrons there without any issue.

With Bottles they worked. I put the exe and dll in ~/.var/app/com.usebottles.bottles/data/bottles/bottles/[xxx]/drive_c/users/[xxx]/downloads/.

As long as you run them sandboxed, e.g. using Bottles via Flatpak, or maybe even Firejail, it's just very unlikely they will affect your system.
