Google Day Dream & 4K screens - the fastest way to see Elite VR in all it's glory?

[cptwhite]

I think there's a lot of Rift and Vive enthusiasts within these pages, but personally, I was disappointed at the resolution when I tried a friend's DK2 kit. As such I've experimented with nVidia's game stream and moonlight for android for use with a Homido HMD. The results were promising but the tracking was lacking the precision you got with the DK2.

Fast forward 12 months and we'll soon be in the era of Google's big VR push with Android Nougat and it's 'Day Dream' specification check list - this includes high res low persistence displays, powerful processors and, most importantly in my vision, improved sensors for accurate head tracking:

This will also be supplemented with Google's own version of a HMD and remote control.

Even with 1440p displays, this might be the fastest way for the Elite Dangerous community can experience higher fidelity VR, above what the Vive and Rift are currently offering players.

I'm seriously considering experimenting with this set-up once it's released, hopefully with a 4K phone display @ 60Mhz...

Has anyone given any consideration to this so far, I couldn't find any thread about day dream when searching the forums...

4k 60 fps on elite with a phone, Gl.

The resolution of the CV1 is better than the DK2. Its not perfect but widely playable.

In fact the current problem of resolution is not the display, its the power needed from the PC. On elite for exemple, you need à 980 gtx to have a smooth experience with max quality. For the moment, no PC can handle a 2x4K vr display @ 90 fps.

We need to wait for optimisation on the VR hardware/software/Driver or more powerfull PC.

My GTX 970 is capable of 1440p mostly solid 60 fps. The phone is simply acting as a dumb display when using GameStream (think streaming on Steam, or the Nvidia shield tablet) also I'm talking about 4k total res, not "per eye"...the current CV1 Rift and Vive are basically providing a little over 1/2 Full HD res per eye, so even a single 4k display would be almost quadrupling the resolution per eye (1920x2160, as opposed to 960x1200 for the Rift / Vive).

Yes it would require beefy hardware, most likely a minimum of the GTX 1080 to run Elite at 4k / 60 fps constant ....4k is exactly 2.25 as many pixels as 1440p.

Looking at a few gaming benchmarks between 1440p and 4k performance for the GTX 1080, the performance hit is typically around 50-55% the frame rate you'd get at 1440p (not quite the 1:1 ratio you'd assume from the 2.25x as many pixels, due to over overheads that aren't affected by resolution). As such if my GTX 970 can pull 60 fps @ 1440p, and it is roughly half the performance of the GTX1080, then the step to 4k on a GTX1080 should, in theory, also be able to manage ~ 60fps in Elite Dangerous.

The image then just needs streaming to a suitable 4k phone with the moonlight app and hey presto, if the tracking is adequate thanks to the Day Dream requirement specs, 4k Elite Dangerous VR is tantalizingly close to reality.

The problem in the VR world is not about screen resolution or pitch density. Money no object, we can easily create a VR HMD with 4K per eye however the problem is that there isn't a GFX card that can drive it. 4K @ 90Hz (twice) along will all the AA/SS post processing requires a lot of muscle. Waaay too much for todays gear at consumer prices anyway.

When the GPUs get much much quicker then we will see the VR HMD scale accordingly.

But you have forgot something. Performance in VR =/= perforce normal gaming. You can't compare the fps between this 2 technologies. on my 980 ti i lose 20/30% fps with the VR compared to a flap display.

The next generation of VR headseat will probably be 2 screens 1260*1440
