Yeah, that’s weird. Like, I get the idea, but the tech just hasn’t caught up to it yet. It needs to be as convenient as just putting on a light pair of glasses - on top of not being especially light or comfortable, VR is still a “process” which requires a degree of effort and adjustment every time you use it, which really kills the whole concept of it being a convenient tool.
I think Apple is probably more likely than most to make something like this take off eventually (Google Glass’ biggest failing was also that it made you look like a total dork, whereas Apple somehow managed to make AirPods cool), but this seems more like a software proof of concept for hardware that doesn’t exist yet.
The one place where I think 8K and up is really gonna matter is VR, when you’ve got pixels inches away from your eyes, but that tech is still niche and a long-term work in progress (Apple jumped the gun trying to make it mainstream too soon). 4K and HDR are great, but 1080p really does still look good even on a big TV.
Also, I’m the biggest freak in the world about input latency but even in the craziest rhythm games, there is no possible way just over 0.1ms of lag is screwing you up unless you are an actual machine. That’s 1/10,000th of a second! Guessing you either meant .1 second or you’re Skynet.
