David Kanter talks to Scott Wasson on the TR Podcast and confirms Nvidia's problems with Maxwell for VR.

He says that in terms of preemption they are "possibly catastrophic" and even behind pre-Skylake Intel.

I don't see VR picking up anytime soon without our minds being linked directly to the interface. No middleman of eyesight.

... Really? headscratch.gif

That's ridiculous.

Same thing was with Low-API like Mantle, but it was the base for as its now whole another level - DX12 and Vulkan.
VR will become a thing in the future. If AMD makes it first to the scene with good performance, they can cash-in really good.

Kanter mentioned the software scheduling too smile.gif I feel vindicated.

The current implementation of VR to me is similar to 3d glasses. Relying on someone's eyesight, will not be the way of the future.

There are a lot of us that can't even use VR for health/medical/comfort reasons.

This. I'm pretty certain that farsighted people won't be able to make use of this without their corrective lenses.

And no, contacts are not a solution!

VR won't be mainstream any time soon, but it will be the must have thing for enthusiasts. Oculus really blew me away with DK1, I had never experienced anything like it. And now it seems to me that Valve will do the same thing again, with freedom of movement and those nifty hand-held controllers. I do remember seeing someone do the same thing a year or two back with an OR and a Razer Hydra. Worked really, really well in Half Life 2.

I have never had any trouble with my glasses on the DK1 and the DK2. Sure, it was a tight fit, and sometimes more comfortable to take my glasses off (which worked fine, they include different optics for near and far-sighter people), but the experience was worth the small comfort-sacrifice.

Ok, I have caught up with the last few pages, and I can understand this is the moment for anyone holding one of AMD's newer (or older cards?) to gloat a little. But, since I don't have one of AMD's newer cards, is there any good news here for Nvidia owners, from the perspective of DX12, other than "don't worry about it, we got you covered by the time DX 12 goes full prime time"?

Does Nvidia have a plan? Any visibility on full DX 12 compliance? Heck, if Intel Igpu can get there before Nvidia, then....

More info here: http://electronicdesign.com/digital-ics/gpu-architecture-improves-embedded-application-support
Hyper-Q allows multiple CPUs to drive a GPU job queue there by reducing GPU idle time. Warning: Spoiler! (Click to show)
Created with GIMP
The Blue squares are the CPU Cores, the Black squares are the Multiple tasks held in the Work Distributor and then the Green part is the SMMs on the GPU side (which contain the Asynchronous Warp Schedulers)

You should really do some big sticky with table of contents and stuff.

So, they had some kind of DX12 functionality even before? I mean, they could do some level of Async processing with CUDA (meaning:compute)?
Still I don't see how we know the distributor is in SW and not HW, but I'm also not sure why it is that bad, except being a bit slower / having higher latency. It does have some advantage in the form of being more flexible.

Frankly, I'm sure I don't see the whole picture, to say the least, though I try to read and understand

And yea, NV's reacting is really low.. they need to switch context quickly and act in a mature way. I don't even understand the big issue - their GPUs are still very fast and they can surely play with the pricing. They have many more iteration to work on
