Mandatory disclaimer about Gamepass:

Gamepass as a model is not sustainable. It is a loss leader, and there is no way it will go like this without enshittifying.

Not only does it lock you into windows via proprietary APIs, making sure wine can never make it work, it also locks you into its subscription, by, well being a subscription.

If you do not have the money to support the creators directly, just choose the lesser evil, pay less than a third (5$) for mullvad, support one of the best VPNs, and just pirate them.

That way it works on Linux, dosent lock you into anything, and instead of supporting a Megacorp, you are supporting a good company. Still not better than supporting the devs, but better than Microsoft.

For the other 12$ you are saving up, just buy the game you liked most every 3-6 months.

That’s how I do it with RE, Rimworld, and everythibg else I play.

But about your question: if you wanna suck Microsoft dick, you can’t just have the best of both worlds.

Either you stream, or you install Win on your Steamdeck, which will tank the Performance and battery life.
