I don't want to go off topic too much, but I think this is interesting in the general sense also in relation to Apple and the M2.
The whole gaming market was around 235 billon USD in 2022, 167 billion is social/mobile gaming (where Apple is well established), 35 billion is "PC", 29.2 billon is console. (

The PC gaming market is not only the dudes with the high end RTX 4090 cards and the colourful rigs, that's just a very vocal minority, if you look in surveys, for example
https://store.steampowered.com/hwsurvey/ most of the "common gaming machine" specs are quite modest. Most common GPU is GTX 1650 from 2019.
The current gen consoles (PS5, Xbox Series X/S) use AMD RDNA 2 GPU tech from 2020, Zen2 CPUs from 2019.
AAA games like Assassins Creed, Cyberpunk 2077, Call of Duty and so on run on all these platforms/specs because the developers and publishers of course want to cater to the complete market (PC and console) and not only to the roughly 0,8% of all Steam users that own a 4080/4090 graphics card and a corresponding CPU.
If we look at the benchmark results of the M2 Ultra, that chip can EASILY handle AAA games. Not necessarily 60 FPS in 4K, but it should be enough. Especially if you have something properly ported like No Man's Sky or Resident Evil Village.
So why does the new Diablo 4 not run on MacOS despite Blizzard being a long term Mac supporter and the hardware can handle it (as proven in several videos on reddit, running it with the new Game Porting Toolkit)? My guess: Too much development effort in comparison to the potential user base. It's not so much about "not good enough" and more about "not enough money to be earned".
Why should and does Apple care? Not because it sells more Mac Pros or Mac Studios, they can/could run the games but you could have a nice gaming setup for a fraction of the price, with an infinite amount of games to choose from (operating system ideologies aside). Right now you can have a better gaming experience on a 500$ console.
My bet is on Vision Pro and what's down the road. Everything they were introducing over the last couple of years, Apple Silicon (and no I don't think they just switched because of the headset), with the excellent performance per watt, Metal 3, Metal FX. It screams high portability, efficiency, performance. And they don't need that stuff primarily for the games right now, they need it for rendering the 3D interfaces, the sensors, the realtime video streams etc. They want this device to stay, they bet a lot on it and it will sit in the living room and at work, literally everywhere. It might replace the smart phones and laptops as we know them today, or at least be something like a standard household device (I'm not talking next year, more like in 5–10 years.) and a big part of the daily usage is entertainment and so is gaming.
If they want it to succeed, they need the games.
And they care, they put a lot of effort in the hardware but also in software to make it more attractive to bring games into their ecosystem.
