@ahau there's some side by side comparisons of PC Vs Quest 1/2 games here https://youtu.be/kwUUzNwJD7U

Evidently there's been a lot of careful optimisation work to allow games to work on Quest, but you can see how the reduced poly count and texture limits have reduced the detail. Still playable, and perhaps if you've seen nothing else that's fine, but I'll be sticking with an RTX card and a cabled headset for the foreseeable future.
