From what I could gather the resolution on the Rift S is 1,280 × 1,440 per-eye (2,560 × 1,440 total) and the Quest is 1,440 × 1,600 per-eye (2,880 × 1,600 total) [0], shouldn't the one rending on a desktop GPU have higher resolution? Maybe the source is nor right as it's slightly outdated, but I couldn't find actual numbers in the website.
Also, it would have been nice to get the snap855, but probably would have made the headset a bit too expensive for the target market. The only thing that is miles ahead of the Go is the tracking from what I can see. Not worth updating for how little I use it.
