VR SM Projection, it's likely compute based, and their version of True Audio, also compute based calculations for sounds.
AMD has signal it's plan since the start of the year.
Vega is not due til Q4 2016 or Q1 2017.
Polaris 11 is entry. Polaris 10 is mainstream. Both small chips.
They aren't going to compete with 1080 and 1070 because it's in a separate market segment in terms of price, power usage, performance profile.
NV can sell the 1070 and 1080 at whatever price they deem is best for profits until Vega arrives. Even then, who here expects Vega w/ HBM2 to be cheap? Nobody should.
This is why I said get used to the new expensive mid-range.

As far as I can tell multi-projection just sounds like a slightly fancier version of multi-resolution rendering which was present on Maxwell, so I don't really think there's anything stopping Nvidia from implementing it for Maxwell as well (other than the fact that Nvidia obviously want people to upgrade to Pascal).

Improving on Multi-Res technology this technique allows for non linear pixel density within a render target. This can be tuned to match the final output display properties of a Head Mounted Display (HMD). Scale values foreshorten the scene continuously so the viewport provides a gradual change in sampling. Fewer viewports are used, improving efficiency. The result is a simpler solution than Multi-Res shading which provides higher performance.
Vertex projection happens in the vertex shader and they are talking about single pass stereo rendering. This is clearly gfx pipe lingo, compute has nothing to do with it.VR SM Projection, it's likely compute based, and their version of True Audio, also compute based calculations for sounds.

Here's hoping Polaris 10 surprises and is mainstream the way it used to be, a reasonably priced card with midrange performance, and drags 1070 prices down too.
Based on what I saw here, AMD is going to be back in the lead as far as perf/w and perf/mm2

Maxwell allows to send the same projected vertex to multiple viewports in a single pass, but if you want to do stereo rendering (i.e. a different projection per eye) you need to transform the geometry twice on Maxwell. Apparently they can do it in a single pass on Pascal, cutting in half the number of vertices sent to the GPU.As far as I can tell multi-projection just sounds like a slightly fancier version of multi-resolution rendering which was present on Maxwell, so I don't really think there's anything stopping Nvidia from implementing it for Maxwell as well (other than the fact that Nvidia obviously want people to upgrade to Pascal).

I think they got it wrong. A viewport only allows to scale and translate geometry, so supporting 16 viewports doesn't mean you can render to 16 point of views in a single pass. IIRC even Maxwell supports rendering to up to 16 viewports in a single pass, but the projected vertex coordinates don't change, you can only swizzle them (useuful for rendering to cubemaps and for voxelization). On Pascal they can apparently transform the vertex twice for the left and the right eye in a single pass. I assume each projected vertex can still be sent to up to 16 viewports.Based on this link, it sounds like Pascal still does 2 separate viewports (with all that this entails) in VR/stereo rendering, and multi projection then takes effect within each individual viewport (via what they call sub viewports)
I don't know how reliable that link is though (it's quite slim on details after all)
I watched everybody at the event hollering in excitement, am I the only one who groaned in disappointment?
So will the partner cards be available at launch for GTX 1080 and at USD 599. The founder edition at USD 699 is a rip off. If GTX 1070 matches GTX 980 Ti perf and has similar OC headroom as 980 Ti it would be a good card to have at USD 379.
It basically was an announcement of a launch, with specs given.Is this a paper launch? Is it a launch? or just an announcement? Specs are out so its something. We still know not a thing for sure about whats in polaris.
How can you tell just by looking at it, that it isn't gimped?I think the real star of the show here is the 1070. It doesnt look gimped e.g. full 8GB of memory and its roughly Titan X speeds at $379. Think these will fly off the shelves.
That covers the areas that are similar to AMD's LiquidVR, but Nvidia has one feather in their cap that AMD doesn't currently support, and that's Multi-Resolution Shading. This one is something I got to preview last year, and it's another clever use of technology. Nvidia's Maxwell 2.0 architecture (sorry, GM107/GM108 and Kepler users, you're out of luck!) has a feature called viewport multicasting, or multi-projection acceleration. They first talked about this at GDC2015, but there weren't a lot of details provided; now, however, we have a concrete example of what Nvidia can do with this feature.
Normally, graphics rendering takes place from a single viewport; if you want to render from a different perspective, you have to recalculate a bunch of stuff and set things up for a new viewport, and that takes a lot of time. Multiport viewcasting allows Nvidia's GM20x architecture to do multiple viewports in a single pass, and what that means for VR is that Nvidia can do nine different scaled viewports. Why would they want to do that? Because a lot of the data normally rendered for VR gets discarded/lost during the preparation for the VR optics.
Not to mention it's on 16nm FF+If the single pass multi-viewport thing actually gets used in VR (not sure if that requires Nvidia VR Works) then it's a big win for the price.
I actually paid for a Radeon Nano at 500$ for VR. The 1070 looks like it might be a better deal, use the same amount of power, and will be faster too.
