It should be possible to pull the rendered fov data from the AVP headset driver, assuming it works like other HMD in that respect.

I’m getting 109x109 on my Index measured in headset using developer Boll’s excellent Wimfov tool which locks the display as unwanted head movement tends to exaggerate field of view markers in steamVR test environments.

Personally have 63.5mm ipd with 0.5mm left offset and 1mm vertical offset, using 3d printed wide Index base and custom pu cushion :kissing_heart:

Something to consider is that Field of View is dynamic and not even constant from frame to frame whilst head in motion, Wimfov measures your own maximum fov rather than maximum rendered.

small adjustment of ipd to centre optical eyebox, and Z distance (lens depth/eye relief) depending on your physiology / craniofacial fit has noticeable consequences for both measurable and perceived field of view / stereo overlap.

Personally I’ve never had satisfactory through the lens camera shots compared viewing to directly with MK1 hairy eyeball

That’s super interesting to hear, I didn’t think ALVR was that good already on the AVP. I’ll hopefully be getting a lend of one soon to test so will be trying ALVR asap ha.

Honestly also haven’t even tried it yet, didnt really bother, just like you I figured it would not be that high quality. On the Quest3 I barely use SteamVR streaming for that same reason, I don’t like the visual impact it has. But probably need to try it LOL.

Now here comes high def sunlight.

Hehe that guy didn’t get it. Obviously the reason for such high nits is pancake where only a small percentage reaches the eye. But as @PimaxUSA once correctly noted this will bring some heat management issues to the table since the energy will be converted to heat.

At a 10:1 ratio we’ll see 1000 nits to the eye, that’s pretty bright compared to a TV that only covers a fraction of your eye sight. I think 1000 nit displays are usable in sun light so pretty on par with real life.

I’m sure technology will move with the times with regards to heat. Attaching heat pipes to the lenses might be a good idea lol

Watching Dune with 1000 nit heat might add to the experience.

Indeed will only yield at max nits 500 - 1000 nits through the pancake. Then you also need to minus brightness further to combat persistence. And then of course the extra heat etc… still cool.

Was reading Burbusters has some test panels that can do 1000hz flickerfree and apparently the 4090 can drive enough frames to match up with 1000fps. They are in talks to see if they might demo it next year at GDC iirc. Bump me will see if can find link for it later.

This might have the detail.
