I normally check online to see if a particular Epic or GOG games is compatible with the Steam Deck before using Heroic to install it, but following that, I haven’t run into any big issues with getting the game to run with the latest Proton version. Though I suspect some games do work better on an older build.

I’ve had mixed success, but probably mostly as a result of it just being fussier to use Heroic and Lutris. Expect to go look up the game on ProtonDB and pay with settings.

Also, the downloading is less robust. I know with Cyberpunk 2077 from GoG, it took several tries before it downloaded successfully.

Overall, the experience of playing a Deck verified Steam game vs. the same game from GoG is like day and… dusk. It works, sometimes with little intervention, but expect to fiddle more.

As an aside, GoG should just support Heroic or Lutris development, and get them to have some streamlined “Community Settings” feature, letting Heroic or Lutris pull and apply an automated settings file.

Maybe a dumb question, but how do I go about getting heroic launcher on the deck?

I played a few games from both Epic and GoG with success. I use Lutris and install the games in the desktop mode. Checking first on lutris web site helps with managing the expectations. Not having community layouts is a bit of a bummer but I add a few of my adjustments if needed. Also note that, I am not talking about AAA, heavily optimized, or online games.

Heroic for Epic, Lutris for GoG, this approach worked best for me so far, I ran into issues when trying to run both stores in one application.

Like the other commenter said, maintaining login session is a bit of a pain (particularly where online functionality is important in the gaming experience like Death Stranding) but it mostly works.

Cloud Save is definitely one of the big flaws. I barely salvaged my Death Stranding save after a Proton version switch (DO NOT do this for a game you have a lot of saves with), because Heroic doesn’t do automatic cloud Save (or maybe it does but it’s Beta? I don’t recall).

Disclaimer: I haven’t tried it.

BUT: I’m both a Deck user and Linux desktop gamer. I believe you should be able to install Epic and GOG both (the launchers) as non-Steam apps, and then they each get installed to fresh Proton prefixes in Steam. No additional tools should be needed besides Steam itself.

I think you can still select a default install location for their games too, since you do get Linux file system access from the prefix (it’s mounted as drive Z).

I’d probably run them both using Proton Experimental, since it tends to be better with other launchers. Or, a later version of Glorious Eggroll. The cases where something doesn’t run on GE or Experimental (but does work with some other Proton version) should be extremely minimal, so using one of those for the whole shebang should give good results. You can freely change the Proton version for the whole launcher if something gives you trouble.

Yes there are other solutions (Heroic, Lutris), but ultimately this should work as well with fewer components. I use this approach for Ubi games that use their daft launcher.

I’ve played a couple of games via Heroic, the only problem I’ve noticed is that sometimes Epic will half log itself out, but you just need to open up Heroic and it’ll log itself back in. Use ProtonDB to check compatibility and running non-Steam games is pretty straightforward!

I’ve used Lutris in the past to good success. Add as non-steam game then look for community control profiles. Also protondb for game settings that may improve performance. I’ll be honest, I’ve been fairly limited with GoG and Epic games.

Neverwinter Nights Enhanced Edition worked well, just a bit small on the screen. Using the touch pad was just fine since that game loves mouse controls.

I have had pretty good success with Heroic and Alien Isolation, which was one of their free games. BUT, I didn’t play for a while and heroic was logged out and I am having difficulty logging back in and getting it working again.

I use Lutris for everything because I am already used to that from my desktop PC. It has installers for most games that would download the needed dependencies and make necessary configuration changes.

I haven’t had a GOG game yet that doesn’t run using the Heroic Launcher. Game save syncing does work mostly, but only for games running under Proton. Native games won’t sync saves without scripting work on your part.

The one problem I’ve had and haven’t seen mentioned on this thread yet is that GOG games installed through Heroic and then launched through the Steam game mode can be so slow. Like, launching No Man’s Sky could take 5 to 10 minutes spinning on the Steam logo before actually launching. I heard one person online say it could be due to Heroic not setting up pre-compiled resources on first launch? I dunno. I’d be open to suggestions.

This is the biggest reason for me considering wiping my steam deck and installing windows. I know that’s heresy in this community but, honestly, I don’t give two shits about my OS, I just want to play the games. If using the touch pad and a set of desktop icons (which is how my desktop pc is configured) works, fine. I’ve never owned a console and don’t need the console experience.

For now I have more Steam backlog than I can play, but when I get around to swapping the SSD…well , I’ll burn that bridge when I get there.
