For EAC to work on Linux you need a native client, I’m guessing the next thing valve should work on is some proton compatibility layer that could link the Linux client with the emulated game.
Actually, they (Codeweavers) are actually working on redesigning WINE to make it possible to support Windows-EAC.
Do people know how EAC works? It’s looking inside the windows kernel loooking in the areas not well covered by patch guard to see if I trusted code is running. Providing it false data to look through in Wine defeats its purpose.
That was a one man project and never really went anywhere.
