Most current viewers no longer need these cubes (external sensors). They do everything with the inside-out method.
This tracking consists of several cameras installed in the same helmet, which by means of algorithms achieve a phenomenal tracking. But as I tell you, practically all viewers already use this system.
If you tried steam link it is something similar in terms of latency and quality, unfortunately the quest depends a lot on the codec chosen, in this case h264 and its limitations when encoding “on the fly” by hardware. Which is worse than doing it by software, but with lower latency.
If in pc games you don’t usually notice the difference between having vsync enabled, you won’t even feel the latency. But if you play shooters on pc and you can’t stand vsync… you will have a similar feeling when using oculus link, by cable less than by wifi obviously.
To “play” go well, try, novelty, hang out, casual games, etc. But simulators, or games with good artistic section (hl alyx for example). No, at least in my opinion, it is not an option to play with quest 2.
But of course, if it’s the first vr headset you’re going to try, forget about it and just enjoy it. Don’t try native video cable headsets, though, as you won’t want to use quest again after taking that step.
Something like when we test an ssd and we no longer look with the same eyes at the hdd, or 144hz monitors and try to return later to a 60hz… although of course, to a lesser extent in this case since “only” would be lost in quality by compression and some latency. (for me it does matter, and a lot).
For development if quest 2 will go well, it is somehow the path that most of those who want to make money with VR will follow.
