I downloaded the game files, mounted the .iso files and added the game to setup.exe to my steam library and installed the game under the mountpoint. When i click play in steam i just get back to the installer. Running the SkyrimSe.exe in steam(located in the CODEX directory) doesnt work. I use Arch Linux.
Are NPCs silent when talking? If so you’ll need to install faudio
into your Wine prefix with Winetricks. Running with Steam may help a little also but l don’t remember if Proton includes faudio by default.
As for the cart crashing that’s probably just Skyrim. The opening cutscene is notoriously buggy.
