Apple fans are starting to return their Vision Pros::The return window for the very first Apple Vision Pro buyers is fast approaching — and some have taken to social media to explain why they won’t be keeping their headsets.
So the quest pro? Foveated rendering only matters if you don’t have the graphics throughput to render it all, so I don’t totally buy that it’s key to a good vr headset so much as helps you get away with cheaper silicon. Maybe enough-lower tdp that it enables slimmer design.
I think foveated rendering also helps with immersion. Being able to blur things you are not specifically looking at and are farther away is a closer match to reality.
Reality doesn’t downsample when you’re not looking at it, your eye does that.
As far as I understand (and do correct me if I’ve got it wrong), your eyes still know they are looking at very small and very rapidly blinking lights in close proximity and in a flat array, which is why it mostly feels like uncanny valley in regards to that exact experience, and why software enhancement/approximation of the effect could be beneficial.

As far as you know. Maybe that’s the reasoning behind weird stuff in quantum mechanics. The cat is both alive and dead until you open the box and look at it.
I don’t really look at it as a symptom of lack of graphics throughput, but more as a benefit of eye tracking, which is also potentially something that benefits, say, the immersion of others through portraying your facial expressions more realistically, or something to that effect. You could also use it as a kind of peripheral for games or software, and apple currently uses it as a mouse, so it’s not totally useless. But I also can’t imagine that most developers are going to be imaginative enough to make good use of it, if we can’t even think of good uses for basic shit, like haptic feedback.
Perhaps it breaks even in terms of allowing them to save money they otherwise would’ve spent on rendering, but I dunno if that’s the case, since the camera has to be pretty low latency, and you have to still dedicate hardware resources to the eye tracking and foveated rendering in order to get it to look good. Weight savings, then? I just don’t really know. I guess we’ll see, if it gets more industry adoption.
