I've been messing with that tool on and off from the day it was available to developers. I'm well aware of it. It's ass.

It's been a few months since I've used it so maybe it's gotten better? But this is Apple and gaming, so I don't have high hopes.

It's not at all comparable to proton other than it does the bare minimum to make a game work. All of the tools and tweaks that go into proton are what make it so good. Maybe for CS2 someones put in the work to make it ok. But whether it's through crossover, wiskey, or whatever else it's been awful for me. Maybe version 2 is better. But even then I doubt it will be as seamless or good as proton is.
