It is 140 in Normal. @SweViver is not using a tool like Hmdq which shows what pimax is requesting to be rendered.

Up to 162 wide. 
If Normal FOV is 140 now, then Index FOV must be like 100�? I mean Small FOV is significantly larger than Index FOV
Check hmdq database. Itâs if mem serves same as either Vive Pro or og Vive which was slightly bigger.
I think it might have been 108? @risa2000
If Index is 108 FOV, then I doubt Oculus Rift S (or especially HP Reverb) is even 80FOV

It has all the headsets tested so far.
5k+ 8k, Og Rift, og Vive, Vive pro, Reverb⌠And more.
Almost had Xtal. But fellow to my awareness hasnât gotten back.
But no a 5" screen provides around 90 to 95 as we know from OSVR.
You really need to use the tools that are freely available.
Og p4k has around 95.
Pimax requests from OpenVR the values that Hmdq pulls & displays. This is what is rendered.

According to the new OpenVR Benchmark, 8KX renders 113 degrees per eye horizontally.

I do not want to open another discussions about numbers of FOV
Sweviver is saying he see some distorsions on normal fov at extreme edge of normal fov
that is a little % of it, I am sure they do not disturb,
but at pimax place
I would cut the distorsions at normal fov. How much measures then normal fov is not important.
while at small fov i would take all the sweet spot How much measures small fov is not important.
and potato/micro/mini/nano fov would be for compatibility with old pc and test purpose
to end the discussion
if distorsions above 140 , there is an area where they are less strong i would take that part making another FOV
and last fov is 170 fov horizontal/200 diagonal
There is really nothing to discuss. The Hmdq pulls what each headset requests to be rendered for FoV from OpenVR. So that is what is rendered.
Large is 162 wide.
Itâs also why itâs unfortunate the fellow on Reddit whom bought the Xtal hasnât gotten back to if he used the hmdq program.

As the maximum fov. What you see can be smaller though.

Whatever it might be, barely anyone uses it. Not because of edge distortion, but because we dont have hardware that can run it. I must say I almost never use Large FOV. Because I hardly feel the difference anyway, and it tanks the performance, especially with PP enabled.

Same for the small bit of extra FoV not really needed. Though have heard SkyrimVR works well with it.

Well Skyrim can do it, especially with FFR enabled. But yeah, itâs really not needed. The only time I feel the extra 20 degrees adds something is in racing simulators. Assetto Corsa races feels faster in Large FOV 
and its one of the very few simulators that can handle 90fps with such resolution.

For reference: Standing up (Iâm 1.80), at the center of the grid, I can count 26 rings in the Index, before I have to squint to resolve the delineation. Donât know what the framing and focus of the photo is, nor the virtual-world height of the headset. :7
I tried 12288 for a little while, but really didnât find the witchspace passage effect compelling enough to spend that much time in it. 
AhemâŚ
First of all: I really wish everybody who persists in using the wrong definition of âsweet spotâ, would cut it out, and take what Risa wrote to heart; We do not need the ambiguity, that keeps tripping up discussions with misunderstandings over and over again.
Then:
I donât know about all the units you have been trying, but my p5k+ (no matter how close and well aligned my eye is to the lens (EDIT: âŚand weâre being told the 8k+ and 8kX have the same lenses)) had about the same per-eye cone of clear vision, and falloff rate of it, as my old Vive and Rift CV1 (in degrees - not percent or something like that), whereas with the Index, properly fitted (and it has a tiny sweet spot (by the proper definition), within which one must be for the desired result), I can easily read text almost all the way out to the edges, before it gets too blurry â unthinkable with the 5k+, whose rapidly degrading focus makes it so that you quickly loose a sense of 3D, just a few degrees out from the centre â an impression I see Pimax users describe again, and again.
âŚand this is very much evidenced by all the people who shove their lenses together, far closer than they should be for a correct projection (setting themselves up for tons of distortion), just to alleviate this matter (which is exacerbated by the canting of the lenses), just so that they can get the narrow bit of view straight ahead in focus in both eyes simultaneously.
The âpretty goodâ edge to edge clarity of the indexâs lenses, is what really sets it apart.

Thanks. Interesting!
By the way, regarding that thread and video. Gotta love Norm for his statement. Made my day

@jojon somehow this tells me you are not wearing your Pimax correctly. I can read things clearly on the sides even beyond the binocular overlap (maybe 120-130 degrees out.
On the other hand, my Index is blurry at least the last 20 degrees around the frame, no matter how I adjust it. I can definitely say my old Samaung Odyssey have a larger âsweviver sweet spotâ
We are all very different it seems.

Youâre welcome⌠
It (hmdq by @risa2000) was announced here:
https://community.openmr.ai/t/hmdq-a-new-tool-for-an-openvr-headset-and-other-hw-introspection/21485
I donât know what to say about that other than I was kinda disappointed that someone like him, on a show like theirs would say that about Pimax (Iâm guessing weâre talking about the stretching/zoom-in of the image, right?)⌠

We are all different, but you can rest assured I leave no stones unturned, when it comes to finding the sweet spot.

It was initial meaning but when VR has evolved ppl starts name âsweetspotâ area without visible blur.
Youâre both right.
