GTA V Heroic specific guide
GTA V's Multiplayer only runs with Wine-GE, a custom version of Wine made by GloriousEggroll. Use the Wine Manager in Heroic to download the latest version of it.
Open up Heroic, hover over GTA V and click the gear icon. This should bring you to the game-specific settings.
- Select your Wine Version: Click the dropdown, then select the correct version (it should have the same name as the one you installed using the Wine Manager)
- Enable the "Auto Install/Update DXVK on Prefix" toggle
When pressing "Play now" in Heroic, after a bit of initialization work, the Rockstar Games Launcher installer pops up. Select your language (Note: I'm not sure if the language selected influences any of the steps in here, I've only tested with English), accept the EULA & ToS and whatnot, and accept the license agreement. In the installation location step, I'd recommend to not change the install location (not sure if this causes issues, but I'd rather not find out). Disable the desktop shortcut checkbox, it won't work (and Heroic offers the option to create better shortcuts anyways).
After some more waiting, you'll get this error:
Oh no, did you do something wrong? Well, no. This error is actually completely normal and, as far as I know, even happens on Windows! Just click "OK", then launch the game again.
This time, the Rockstar Games Launcher will actually launch up and update itself and then install Social Club. Once that's done, you'll finally get a login prompt. Enter your login details (don't worry, you're not insane, keystrokes are a bit delayed) and enable "Remember me" and "Auto sign in".
After more waiting, you'll end up in this screen:
(which is for some reason very dark right now; Halloween edition? Anyways)
You'll see here that GTA V is marked as "Buy now". At this point, you'll need another close (you might even have to kill the "Launcher.exe" process through your Task Manager).
Starting the game again, you'll get a "Cloud Save" message. From testing, I don't think this message actually does anything, as GTA V will save-sync either way. But just in case, click "Enable Cloud Saves"/"Not right now" depending on your preference.
After this, the game will launch like normal and you can finally play
