HP's Reverb VR Pro Headset

The new htc cosmos is expected to have foveated rendering, there's a partnership with NVIDIA and will be supported by rtx20 series VGA, but without eye tracking: a high-res screen with a high res rendering only in the center of the screen and a lower res along the edges / peripheral part.

Oculus project half dome (140° fov and fingers tracking without controllers) maybe does not have eye tracking but can be called true 2nd gen, when we'll have it on a consumer product. A simple screen - even with higher resolution - with two lenses in front of it, uses exactly the same techology of the CV1 and htc vive, so it is hard to call it 2nd gen.

I haven't read anything about the reverb doing any sort of foveated rendering. And I think you will be waiting a very very long time if thats what you consider "real 2nd gen" I think some tech writers latched onto that idea because it "sounds" simple, but in practice FR with eye tracking is incredibly demanding in terms of render times. Just think about how fast your eyes move relative to your head. For FR the headset has to track your eye with almost no latency, send that information to the CPU (more latency), the CPU then has to figure out what you are looking at (more latency), then it has to make the draw calls (more latency), which then get pushed to the GPU, and if you are very lucky you might still be looking at that same spot, or maybe not. Also, from what I've read, Fixed foveated rendering on the pimax apparently looks pretty bad which doesn't surprise me in the least.

 

One thing people here maybe don't get is exactly how bad/demanding DCS is in VR. With my minimally specced system I can pull 90 frames in many VR games on "high" settings (I play Elite Dangerous on the highest settings and basically never have issues), but I struggle with DCS on fairly low settings. So realistically I can see even a 1070 running the HP set for "normal" VR applications but it will probably not be enough for DCS.

HTC are expecting to start selling their Vive pro eye with eye tracking by the end of this summer.

what do you guys think, will a much larger number of pixels increase the load more on GPU or also a bit on CPU?

i am more familiar in the SimRacing universe, i.e. Assetto Corsa, and there we are all still surprised how VR is also occupying the CPU a lot more - compared to non-VR.

This is starting to look very interesting

Wow, that is pretty cool... thanks for the post.

I can already imagine the conversation with Wifey-pooh...

"what do you have there??"

"Oh, this babe?"

"yeah, that?"

"it's called an HP Reverb... It's much better than that old Oculus thingy I've been using..."

"How much??"

"well, it was on sale, for $599..."

"and what's that??"

"That? well that's just an added accessory... they call it a 2080TI, but never mind that...." ;):megalol:

Tell her you got the " accessory " on sale too.....makes all the difference :) My wife buys stuff she doesn't even need or want 'cause , you know , "Sale" !

Thanks for sharing; I am very likely getting one of those instead of the Rift S now. But what prompts these devs to go with LCD instead of AMOLED? Is that just to keep the price down?

DCS will be a slide show in this one

I've read nothing to suggest the cosmos will have foeveated rendering. In fact quite the opposite, the cosmos is expected to be a qualcomm ref clone, and therfore "might" have 2160 screens. The Vive "eye" will have eye tracking but its a separate product entirely and in that case it will be used to improve virtual avatars not FR...

Half dome is going nowhere. Its why Brendan Iribe quit occulus (co founder). He was quoted as saying he didn't want to be part of the race to the bottom strategy that occulus was pursuing (rift-S).

Maybe. Time will tell.

Or.....don't mention the Reverb. Not like she's going to know a Vive from a Rift from a Reverb. And the 2080Ti is *INSIDE* the computer. You're home free!!!:D

Availability is one important factor. Not much supply. Samsung as an example won't sell their displays to competitors in critical areas.

Its got 20% more pixels than a pimax 5k... So in "theory" its in the runnable by DCS ballpark... Worst case you can dial the PD down under 1.0.

It's concentrated in a lot less FOV than the Pimax though and more FOV = more stuff needing to be drawn. It should be runnable at 1.0 - like I said I've run my Odyssey (which has basically the same FOV) at 2160x2160 with PD and that was playable without visible stutters.

Have there been any clues about the actual release date?

I don't think foveated rendering is going to save us in DCS unfortunately - it sounds like it's something the game engine will have to support, and so even if it's added to VR headsets and the major unreal/unity game engines, the chances of it coming to DCS anytime soon are slim.

Ha, nice! But when the gig is up, dog house city eh? ;):lol:

All the reviews I read talked about an end of April release, in the US at least, no word for availability in others regions for now.

Yup... drawin a bigger fov at lower res is more demanding.

Maybe. Time will tell.

Ditto, I was told on this forum dozens of times the same thing about the Odyssey/Odyssey+ and Pimax5k too, and that wasn't my experience at all, especially with the Odyssey+. Eliminated SDE, virtually no god rays, and at 200% and 1.3 I have a pretty rock solid 45 with the re projection mod enabled, and 45 to 70fps with it off, in the Odyssey+. Pimax, not so much, but with settings adjusted, it's not a slide show by any means.

@twobells,

I don't understand the HP Reverb calculation of pixels per degree. 2160 / 114 degrees = 18.9 so either the pixels per degree is less (at least horizontally ) or the field of view is. (25 ppd no way )

114 fov is most likely measured diagonal
