Sony VR Headset/Project Morpheus/PlayStation VR
This was already discussed here back when this was all posted on reddit.
In the end, we cannot say for sure what are true rendering requirements PSVR. We must wait.
When I discovered this thread I went back and read every page, but I don't recall reading the YantraVR stuff as being around the barrel distortion render target size, having said that at the time I hadn't taken that side of what was being discussed on board.
A comment just through on the NeoGaf thread also seems to shoot the whole YantraVR reduced render target argument down in flames anyway:
ServerSurfer:
but I've actually been in touch with a PSVR dev who kinda shot down my theory anyway. lol
They confirmed that just like PCVR, Sony are recommending a rendering target 1.4x on both axes. I was told you could render at 1x if you want, but that results in a softer image. The visuals in their particular game aren't super complex, so they actually use a scaling factor of 1.7x(!) on both PCVR and PSVR, despite targeting 120 fps native on the latter. They may even as so high as 2x.
So yeah, it sounds like Sony don't really have anything special going on here, or if they do, this (3rd-party) dev doesn't know about it.
The distortion is not as extreme (no fisheye). They can also render the distortion 'outwards', into the hidden mesh area (effectively super sampling it), then compress it again. Now you have only super sampled the required areas. The Sony lenses are not as spherical (look at an unwrapped image to compare them). This is all speculation
I'm so tired of waiting, I can't remember a product that was teased with hands-on at trade shows for so long without a price or a date.
Can you imagine the internet meltdown that would happen if we don't learn anything new on March 15?
we talked about it. Dunno Yantra but we talked about the higher res rendering for distortion . Some seem to think sony has a magical fix to allow them to target 1080p as they never talk about a higher resolution.
The 1.4x seems likely as its what the Vive and Rift are using

See page 4 for confirmation
If you go further to page 58. You can see that Valve has implemented Stencil Mesh to help reduce the load by rermoving the hidden area.
They claim it results in a 17% fill rate reduction.
Then optimized warp mesh reduces costs by 15%
No stencil mesh: VR 1512x1680x2 @ 90hz = 457mps With stencil mesh Vr 1512x1780x2@90hz = 378mps .
I would wager sony is also doing this.
but sony is well-known for ass SDK right? are we sure they have all of those bleeding edge tricks?
or sony do have changed with PS4 and its SDK is super nice and at the bleeding edge of tech.
btw
Fw 3.50 beta have PSVR health and safety
PSN got overhauled
then march 15th...
maybe not only PSVR, but they will also announce something else that also big? OS overhaul like xbox has done for years? Special OS GUI for VR and its apps to consume non-VR stuff... like wrapping game, videos, youtube, etc
or, even more stability!

Wouldn't this have been raised when Sony was talking about rendering requirements to the devs? It'd be a major oversight to state the need for 90/120 Hz and talk about the rendering requirements increase from a TV game, but not mention an additional 2x rendering cost for oversampling.
Not saying it's not true, but it'd mean their dev talks were lax.
Some magical transform ability would also go some way to explaining the claimed increased efficiencies and why a PS4 can supposedly perform as well in VR as other headsets on more powerful PC rigs.
? Where's this coming from. AFAIK the SDK is very good swith excellent tools.
I think the poor SDK stuff comes from the ps3 and before.
I also doubt the PS VR will be out in March , I doubt we will see it before summer.
The only dev talks we've seen are non NDA'd . Its quite possible that devs who signed the NDA (which is anyone actually working on a vr game for them) would be given more information than the dev talks.
Remember the public dev talks are just as much PR as they are meaningful information a bit of miss information would only help them
Anyone worried about optics, at least on Sony's device, probably hasn't used any of their cameras with electronic viewfinders. Those are OLED screens with 2.3M pixels (if memory serves me right), but tiny, tiny screens. And the viewfinders are just gorgeous, little to no screen door effect, great magnification and no 'side effects'.
I'm pretty sure that working out the optics for those little things is much, much harder and more expensive than slapping a couple of lenses in front of a nice 5" screen.

it depends on the ppi doesn't it. If its a 1.5 inch view finder with 2.3m pixels that would be a seriously high ppi.
The HMZ-T1 (1000 euros though 
) has excellent optics as well. For the high-end Sony viewfinders they use tiny 1024*768 resolution RGB OLED screens (1024*768*3subpixels=) 2.3 million pixels indeed. They do have a smaller field of view so the 'no screen door' -part could be explained by that.
I believe we have official confirmation that PSVR uses a scaling factor, at least the current version of DRIVECLUB (I'm not shouting, that's how the game is spelled )

That's actually subpixel count.
No, it's angular FOV! PPI is irrelevant as that value doesn't figure in viewing distance. The angular FOV of the viewfinder is much smaller than a VR headset, so the pixel density is a lot higher. The topics for those tiny screens are likely easier to manage as they aren't so wide and prone to artefacts.
ppi is relative; if you view the display in a way that it covers 100 degrees of your vision; it will have a lower ppi then when viewed further away, even though it's still the same display
As long they showcase the serious intent into well supporting PSVR with good hardware, game software, partnerships and PS4 system services... all will be fine with me. Price/date is not as important as those things [but I would like 300€ or less for camera/move-less bundle
].And we will definitely learn SOMETHING new on March 15.
No, they are good with it. PS3 maybe had some issues early on, but with Vita and PS4 they did stellar job with SDK and support. And also, they don't advertise when they enable better things like MS currently does. We had to dig trough middleware logs just to find that Sony has already activated 7th CPU core on PS4 [BTW it is confirmed that all devs now have access to 7th CPU core, indie dev that works on Kholat talked how he utilized it].
I think on 15th March they will announce that they will soon reveal the pricing and release date.
/lights come on
Yosp: "Ladies and gentleman, we are proud to announce that we have extended the main cable of PSVR to 4 meters."
/audience claps
Yosp: "And now, lets recap everything we talked about in last 2 years and go play old demos!"

There you go, we learned something.
