The Valve Index has an IPD adjustment slider on the bottom. I can tell that it does...something...but, with very wide margins, I can't tell what the right setting actually is for my eyes. Anything +/- a hell of a lot all just looks fine. So maybe it doesn't actually matter that much.

It changes how nice the depth perceptions works, reduces nausea if set properly.

Similar for me with an Oculus Quest. Maybe if I left the adjustment at one or the other extreme for an extended session, I'd notice something, but for my usual 30 minutes or so, I haven't seen any difference between settings.

  I've found it affects how sharp lines look for me on Quest. I like to find a vertical line somewhere and dial in until it looks decently sharp.

    Try sideloading QuestIPD [0]. It shows a test pattern that's supposed to help set the slider properly, and it shows you the exact setting value you're using. [0] https://sidequestvr.com/#/app/303 https://sidequestvr.com/#/app/303

      The latest software update for the Oculus Quest shows you what you’re setting the slider too now as well, FWIW.

when your ipd is off its roughly the same thing as being slightly cross-eyed or slightly wall-eyed. if its small enough and the game is low-res enough it can not matter, but if you feel "eye strain" or a sortof between-the-eyes headache after playing for 20 minutes thats where it comes from. its subtle so it really gets you over time, not at any one moment. here's a good howto on measuring your ipd to get it right: http://doc-ok.org/?p=898 http://doc-ok.org/?p=898

Speaking of the index, try enabling the camera passthrough to experience severely mismatched IPD and camera spacing. I imagine this is what it feels like if ipd is set too high, but cant say because i leave it set at maximum.

In this article's terminology, I think that slider controls "IAD", and the reason why it doesn't change much is explained under the subheading "Collimated images"

  > In this article's terminology, I think that slider controls "IAD" Of course it does; obviously the slider doesn't move your pupils. But it's meant to compensate for your personal average IPD. I think you're right that the collimated images section probably explains the result, though.

The Index also has relief adjustment, which is high on his wish list at the end of the article.
