So easy to do, I can install Epic store, game pass and what not without even needing lutris. This installer is even programmed to not need any adjusting. Now I have absolutely no reason to even need windows side loaded. The only issue with launchers is controllers still not configured properly so you have to use touch screen, keyboard works fine but have a little patience, install the game then launch it. Controls work great otherwise on game.
