> why aren’t we seeing it from the major publishers?

Models are just recently capable of reliably doing this type of deeper work, which is why you're only seeing it now. There hasn't really been enough time to see it. And still, why? Modern gaming on Linux is almost always on accident, with the devs targeting windows, with no thoughts of Linux at all. Seems like it would make more sense to point the AI at wine, to make linux run Windows better.
