The tools for this are interesting. But I think the headline was slightly misleading to be called a Proton-like tool. This is more of a diagnostic tool than a translation layer to play games for troubleshooting than anything else. Even maxed out M2 Ultra devices are only getting like 30-40 FPS on Cyberpunk because of how many resources the tool uses. I personally hope it does incentivize some devs to port to macOS as a primary Mac user. Devs need to see a cost benefit to do it. Apple convincing one dev per year to port a AAA game to Mac is not enough of an effort to actually convince people of anything.

That being said, Apple has had very inconsistent messaging regarding gaming in the past. And Steve Jobs notoriously did not care for gaming. Really, the only gaming success they are having right now is mobile games. And despite on/off rumors of a dedicated gaming device. I would just not be encouraged based on the majority of offerings on Apple Arcade that there would be much worthwhile. The only reason I even have it is because my phone plan includes it. Otherwise I would never touch it.
