The Epic Games Store comes to the game manager Lutris, giving you an even better place to deal with your game library split across many different stores. On top of that it also supports Steam for Windows as a game source, for those titles you can't get working directly through Proton.
Now this means that Lutris can help you manage Epic Games Store, GOG, Humble Store, Steam (Linux/Windows), DOSBox, Emulators and more. Even more helpful is that Lutris games can be launched from Steam, you can disable 3rd party services you don't want, there's support now for DXVK-NVAPI and DLSS and VKD3D is now an option by itself.
Even more came with this release like the ability to use AMD FidelityFX Super Resolution (FSR) with compatible versions of Wine, gamescope is an option, Esync was enabled by default, Dolphin was added as a game source, installers for GOG were improved, an improved monitor for your Steam games and much more.
Sounds like this is one of the biggest releases of the open source app yet.
