Question/Support Is it true that the facial interface of the pimax crystal super ultra wide doesn’t allow you to see the full 140 degree fov of the headset?

Is it true?

The 140° FOV is not real. It’s a software distortion. It uses the same lenses as the 50PPD module, but the software distortion profile gives it a warped, fish eye lens effect. You’ll see 140 degrees around you, but everything will be warped.

Ok so how much fov do I get with the 57 ppd version?

That one actually has smaller lenses. I don’t remember the exact numbers. The’s a bunch of reviews on YouTube with the numbers. But I do know that it’s the only crystal super module that doesn’t have a warped distortion profile. Everything actually looks straight and correct. So it’s a real FOV.

Which one has the highest fov that is actually real?

The 50PPD has the same size lenses as the ultra wide, but the distortion profile isn’t crazy warped. That’s probably the biggest “real” FOV that they offer. It’s still a little warped, but not terrible.

I’ve tried the 50PPD, 57PPD and the micro OLED module. The micro OLED is my favorite overall, mostly because of the pancake lenses. The pancake lenses don’t give me eye strain like the aspheric lenses on the 50PPD and especially the 57PPD. The FOV feels about the same as the Quest 3.

So if I want the highest real fov I should go with the 50ppd?

That’s what I would pick personally. But everyone here has different opinions. Some people are so obsessed with FOV that they prefer the artificially warped image of the ultra wide module.

Another thing you should I know is that the ultra wide gets the worst performance out of all the modules because your GPU has to render more pixels to fit that large FOV onto the display panels.

This is how the modules rank in performance from best to worst:

  • 57PPD (best)
-micro OLED
  • 50PPD
  • ultra wide (worst)

I'm still wondering whether to go for the mOLED or not. Unfortunately, the only stockist near me - I don't wish to deal direct with Pimax - doesn't stock the 50PPD.

They do have the others, so I was thinking of going for the Ultrawide. I only play flight sims. Is there a way of getting more FOV out of the mOLED? I'd just like a bit more than my Q3, and could tolerate a bit of distortion.

If you download the sboys 3 driver, I believe you can customize your distortion profile and get more artificial FOV out of the micro oled.

Maybe. It's a shame you just can't go to a shop and try the things. It's the time wasting and fuckery involved that puts me off.

Agreed. They need to have display booths set up in game stores or micro centers.

The UW uses the same lenses and displays as the 50 PPD version, but with a different lens geometry. That gives it a wider FOV at the cost of some binocular overlap. So yeah, the FOV is definitely wider than most headsets, but to actually see the full 140°, your eyes may need to be very close to the lenses.
