The StarVR PPI has got to be lower than even the Playstation VR. The StarVR is just 1830 x 1464 per eye spread across 210 degrees H.
The StarVR might literally be the lowest resolution VR headset on the market.
The old Oculus DK2 was 960 x 1080 per eye over 100 degrees H and this is 1830 x 1464 over 210 degrees H. Heck the DK2 actually has higher horizontal and vertical PPI than the StarVR.
That’s a big piece of bread with only a tiny amount of butter to cover it.
