The Rosetta games (which is most of them) suck though, and Crossover/Whisky is such a hit or miss experience.
On the other hand, with GFN I can turn everything up to ultra and it looks great, and there's no fan or noise at all and barely sips the battery.
My work machine is a M2 Max and I have a studio display. Every day I fight the temptation to install Steam and load up No Man's Sky on it...
I don't think the M2 can comfortably drive that resolution at 60 fps though :/ As much as I love Apple Silicon, the GPU is a lot weaker than a RTX card. Especially since it lacks any of the AI features.
GFN offers day passes and works with your Steam library if you want to give it a shot. You don't have to install anything, just sign up for a day and you can play No Man's Sky in a browser window at max settings. (But I think you might need the GFN app to play at full native resolution or with proper HDR, not sure).
I wonder how DLSS and frame gen affects power usage. Presumably they save power vs drawing real frames, but I haven't tested it...?
