Oculus founder Palmer Luckey says Rift S is only suitable for about 70 percent of the...

  1. The Oculus Rift CV1 offered mechanical IPD adjustment with a supported range of about 58mm to 72mm. IPD is interpupillary distance, or the distance between your eyes. Having the IPD at the correct distance helps match the field curvature on the focal plane, corrects geometric distortion, ensures proper world scaling and more.

    In essence, it is an important cog in nailing the perfect optical experience and one that is missing in the latest Oculus headset.

    As Palmer Luckey recently highlighted, the Rift S uses two lenses that are fixed at about 64mm apart. That’s great for the average person, or for about 70 percent of the population. Everyone else outside this “Cinderella” range, Luckey said, will have to contend with minor eyestrain at best and far more troubling issues at the extremes.

    “Everyone else is screwed, including me. Imagery is hard to fuse, details are blurry, distortion is wrong, mismatched pupil swim screws up VOR, and everything is at the wrong scale.”

    Software adjustments can help fix one issue but is in no way comparable to an actual IPD adjustment mechanism, Luckey said.

    Given the lack of mechanical IPD adjustment, you’ll likely want to take the Rift S for a test run before shelling out $399 for a headset that may not offer an optimal visual experience.

    I wasn't planning on buying an S anyway, because the only upgrade from the original Rift is the higher res screen; but this is a definite no for me now because the old Rift barely gets close enough to my 55mm IPD to be comfortable. I've used headsets without adjustable IPD and it is a horrible, headache inducing experience. I have to agree with Luckey, and certainly think any headset in this price range should include mechanical IPD adjustment. I can't imagine it would really cost that much more.

    Given that this is priced more then the original Rift, cost isn't the issue for them. Single screen, no external sesnors, by all measures the Rift S should be cheaper then the original Rift. It's the same price as the Oculus Quest, only it has a worse screen, no IPD adjustment, and no SoC. It just seems greedy.

    No IPD adjust, LCD instead of OLED, and lower refresh rate. its a sidegrade at BEST.

    I how much IPD difference can one tolerate? 1mm? 2? 3 is already a stretch?

    Tolerance depends on the pupil. The larger the pupil the bigger the tolerance.

    I'm more into buying the Quest than the Rift S since I don't really have a powerful PC to run it, but I should be OK in terms of the IPD.
