MRTV Subjective FOV Comparison

In that case Pimax must have dished out a lot of money over the last two years because this was confirmed by a range of users.

Actually, the fact that Large was measured at only 160° was a bit of an issue for Pimax because they had claimed it to be 170°…

(but of course measuring FoV is tricky as it depends on a lot of factors partly associated with the users head-shape and eye position and partly with headset-related factors such as foams thinkness, etc…).

There is a possibility that Pimax quietly moved to a 140° degree FoV for the 8KX. If that truly is the case, you can rest assured this will be validated within the coming days by a number of people having received theirs.

So why get excited and try to argue the result in a debate rather than just wait & see ?

:joy:

I just literally did the same, including the 2$ tip !

It is a proven tool and I wanted to get it for some time already but had been too lazy. You are supporting the Spanish group of Real o Virtual who have afforded great efforts trying to make thorough reviews of VR hardware, so our money is well-spent !

my measurement: 158/160 degrees. 158 i can see the lines, at 160 not anymore

138/140 @normal
118/120 @small
98/100 @potato

always rebooting the HMD

checked with my VivePro with gearVR mod:

106/108 hor and 132/134 vert (lower half, upper half was out of sight earlier)

that was my reasoning, too! :+1:

Thanks a lot so there is a problem indeed
What do you think now Dmel642 ???

No big surprise, I have to say. Sorry, but it just seemed so obvious that Seb’s headset had switched to Normal…

This of course tells us that we should take Seb’s & derDod’s impressions of the 8KX as compared to the G2 with a grain of salt…

Not sure if this is the issue but since way back when switching FOV to a bigger value You had to restart SteamVR for it to actually change, while changing it to a smaller value didn’t require a restart of SteamVR.

Yepp, also first thought - wah, this costs money. But after looking at the stuff you can do with it - very interesting tool and absolutely worth it!

Thanks for also testing! So I’m not crazy/blind. Or we both are :wink:

True. But the perceived value is very subjective and depends on many factors. You can see how different values he got on same HMD - Index (Min vs Max). 112 vs 130 is ~16 % difference, 140 vs 160 is only 14 %, so it could be even within measurement error (e.g. he measured Pimax on MIN position, on MAX position he could perhaps get close to 160).

All in all as we don’t know what positions where the HMD’s measured the comparison serves at best as curiosity. If it is presented as real (objective) fact then that would be a problem. Perhaps he could do MIN/MAX for all HMD’s and then it would be more informative (but still not complete truth as different people will perceive differently).

In thr og 8k at time of release Seb’s RoV tests coincided with the around the 160 in Large. So it is indeed odd that he is getting 140. But could be due to the comfort kit or the fact he has the ces pre production model.

@mixedrealityTV
A simple test would be for him to installl the comfort kit on the 5k+ and the 8k+ and test using the RoV tool he used. I am leaning towards it might be the 8kX unit he currently has vs the final release model.

The Aryisan has had a variance in it’s FoV from 120 to 128 in it’s max. No 140 even in rendering.

but then i assume he takes the same measurement standard on all headsets and the deviation must be there also. My guess something went wrong with switching to large fov mode
he has to do an rectification i think

He already said he will do the measurements again on the 8K X

using the standalone version
I only get 104 hz 128 v on my vive pro gear must be my neanderthal scull shape
5k+ gives 160/140/120 though

did you move the hmd to your face as close as possible? You can alter the distance similar to the OG Vive.

Yes that seems like most reasonable explanation. But I think he knows well how to switch modes on Pimax. Could still be some driver/Pitool bug, but I suspect it might be just eyes being too far away from lenses (MIN position).

He just forgot to restart steam and then had another beer lol

edit
It must have taken ages to check all headsets , he missed this “obvious” discrepancy ,a bit too eager to publish maybe

yeah sure but sometimes but i noticed myself it’s easy to make a mistake thinking your in large fov as the difference is not that big

1 Like

only difference I seem to notice is the corners are rounded in 140

But when you are doing a FoV comparison he should have noticed the discrepancy and double-checked. And if he says he tried both normal and large, why didn‘t occur to him that it‘s odd that they will have shown the same values… weird. But okay, possibly a beer too much and not caring about the newer Pimax headsets anymore because they don‘t run well on his system anyhow.
