There's lots of options? GPT, WINE Crossover, Luna, Boosteroid, Shadow.tech... none of them run as well as GeForce Now, though. Or a dedicated gaming PC.
I have a M2 Max and GFN is much much easier than trying to set something up with GPT (Game Porting Toolkit) and Whisky, and much faster & quieter too. An RTX 4080 running in their data center means no local heat and noise.
