Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      You want to know something about how bullshit insane our brains are? OK, so there's a physical problem with our eyes: We move them in short fast bursts called "saccades", right? very quick, synchronized movements. The only problem is: they go all blurry and useless during this

      I feel like there are huge advances to be made in VR by reverse engineering the eyes and the brain's visual processing on a deeper level. Can probably get better, more realistic experience at less than 10% of current rendering cost.

      Yup! And Some forms of it are being worked on. Foveated rendering, for example, is a trick where you put an eye-tracker in the headset, and only render at max quality where the user is looking. Everywhere else can be low quality.

      What kind of latency requirement is there for delivering the hq version?

      I would guess 20ms or lower latency.

      That's very likely several times too high if ppl are reporting need for 90fps. But it could be even worse if eye movement is faster.
