If you already have a bottle for the Heroic Games Launcher and GTA V is hanging on the loading screen, open the Rockstar Games Launcher from the CrossOver bottle before launching GTA V.
To create a new bottle, from the CrossOver menu, select Bottle > New Bottle.
Name the bottle Heroic, and select Win7 64-bit from the New Bottle Type list.
Select the Heroic Bottle in CrossOver.
From the CrossOver menu, navigate to Bottle > Settings and select DXVK Backend for D3D11 to enable DXVK in the Heroic bottle.
If you have not downloaded the Heroic Games Launcher (v 1.10.3 or later), you can do so here. Once installed, open the Heroic Games Launcher, and follow the prompts to link your Epic account.
In Heroic, navigate to Settings > Wine and select your CrossOver install from Wine Version. Once a selection is made, the CrossOver Bottle field will appear and default to Heroic.
Note: If you don't see the Bottle field and Heroic prefilled a Wine Version, try manually selecting your CrossOver installation.
Now that Heroic is installed and linked with Epic, you can install titles directly from the Heroic Games Launcher. Once installed, launch the title, and enjoy. Consider yourself heroically epic!
