Really? The article says “well-known method”, not “all vr headsets already doing”. From what I can find, DeepFovea and others were only work in progress (summer 2020) at best, in contrast to mainstream tech. Is there more info on that?

I don't think most support foveated rendering, currently.

But there are consumed ones available / becoming available:

* HP Reverb G2 Omnicept Edition

* HTC Vive Pro Eye

Just because they track eyes doesn't mean they gonna use it for rendering. That's probably for input.

Directly from the HP product page:

"NVIDIA VR Ready Quadro or GeForce Turing based GPU required for foveated rendering. For developers, Unity foveated rendering plug-in and run-time are also required and available from the Unity Store or HP Developer Portal"

Nobody does that and it's not possible due to GPU latency.

Eyeballs rotate very fast, up to 1000°/s. Fovea has just under 1° of high resolution. You gonna need to render 1000 FPS with 1 frame of latency to catch up.

GPUs can't do that. They evolved for decades optimizing for throughput at 60Hz, not latency at 1000Hz.

IIRC snappy eye movement makes us essentialy blind not only during the movement itself, but for a brief time after the eye settles also.

Foveated rendering (where IR cameras look where pupils are looking, passing this info to PC and the frames rendering with high detail only in that spot) was already demonstrated to be working well and fast enough to not be noticable.

It is not present in any consumer VR headset, and the software side is also not yet plug&play

Would this enable me to look off to the edge of my headset and not have it be blurry? It's been rough training myself to turn my head and made me realize how much I rely on that ability for vision in general.

Unfortunately no, that's an effect of lens distortion.
