Hands-on with Tiramisu, Meta's “hyperrealistic” VR research prototype with beyond-retinal resolution, high brightness and contrast, and a narrow field of view.
Curiously this piece dives into PPD explaiming about "Butterscotch" prototype at 56 PPD and placing this at 90 PPD, without touching on a device that's in the marketplace with "50 to 70 PPD" per Spectrum in https://spectrum.ieee.org/apple-vision-pro — looks like FOV tradeoffs also apply here at just 33 degrees.
While this is as yet still a research prototype, it's ... illuminating ... to read these two stories back to back and see the new line from Meta about importance of clarity as Meta is working to become more competitive.
What was most notable about the Boba 3 demo is that there was no deal-breaking "catch". The three other Meta research prototypes I've tried have, in pursuit of pushing the frontier of a particular aspect of HMD display systems, involved noticeable and obvious tradeoffs:
- Starburst delivered stunning 20,000 nits brightness, but in a headset so comically big and heavy it had to be suspended from above with cables, and so hot that it had enormous cooling fans on the top.
- Butterscotch Varifocal delivered near-"retinal" resolution and varifocal optics, but in a thick and heavy headset with only 50° horizontal field of view.
- Tiramisu combines beyond "retinal" resolution with high brightness and contrast. But it's also thick and heavy, and has a field of view of just 33°.
Bottom line: competition in this arena is a very good thing.

From yet another article ( https://www.uploadvr.com/meta-boba-3-prototype-hands-on-ultr... ):
