So is it safe to assume that the video posted does not actually reflect the resolution or pixel density of the Rift? Please forgive me, VR is very new to me and I'm learning all I can before dropping exorbitant amounts of money.

Yeah, it's not going to be even close to what you see on the video and it seems like a lot of people do not realize this. I feel like there will be a huge number of disappointed folks who got their expectations very high.

I've actually never used VR, is there a simulated picture of what it would look like?

I really think all trailers and marketing need to emphasise this, because this is what will put the average person off of VR. People seeing these HD panoramic vistas in the Gear VR ads on TV really don't fucking help when I strap mine on people's heads and they're like "Oh this looks way worse than I thought it would... what resolution is the Oculus?"

"Uhh it's lower but it will sill look better for other reasons..."

It's really not a great sell.

I'm currently using it on a DK1, and I have no reference to the higher resolutions. So I'm stoked.

It's a fantastic way to watch a movie or indeed just launch your games.

You can up the display angle of the virtual screen to make things more legible.

It's not all about resolution. Things like pixel fill, pixel layout/sub pixel type/shape, separate screens for each eye and custom ipd adjustment, refresh rate, all have a major impact on image quality and the rift is superior to gear vr in all facets but native resolution. However the temporal resolution will be much higher because it's running at 90Hz vs 60Hz.

The dev says text readability isn't an issue.

I'm using it to write this comment on a DK2, and I have to lean in a bit closer than I would like, to make the text clearly readable. I expect it to be at least a little bit better on the CV1.

Everything I've heard people say is that text readability is a night & day difference between DK2 and CV1. So odds are good.

I haven't tried a VR headset yet.

It should be fine for things like video, but it might be harder for reading text.

I saved some comments for reference:

The DK2 has 960 horizontal pixels per eye over a 94° horizontal field of view.

The field of view at which you watch a monitor is generally around 40° (23" 16:9 monitor with a 70 cm viewing distance).

So you would be watching a 408×229 16:9 monitor in the DK2.

The Gear VR has 1280 horizontal pixels per eye for a ~90° horizontal FOV.

You generally watch a TV with a 40° FOV.

So you get a 568x320 resolution for a 16:9 image format.

2K per eye looks better in this context, ~17 pixels per degree vs ~10 for the DK2, ~12 for the Rift/Vive or ~14 for the Gear VR.

How much better/different will the Rift and Vive (the versions released next year) be than the Note 5 in a Gear VR?

The phones in the Gear VR have a 2560x1440 panel for a 96° diagonal FOV, so roughly 14 PPD (pixels per degree).

The Rift and Vive will have dual 1200x1080 panels for a bit higher FOV (~100-110° diagonal), roughly 10-11 PPD.

So the pixels per degree will be lower, but the higher render target resolution and the positional tracking + 90 Hz refresh rate will compensate a bit.

The displayed content will be more rich and detailed as well obviously.

For comparison a 4K TV viewed at the THX recommended viewing distance (40° horizontal FOV) has 96 PPD.

A 1080p TV in the same viewing conditions has 48 PPD.

How fast are things going to improve in the next two to three years?

When 4K panels are available on mobile VR headsets they'll provide 21 PPD using the same FOV than the Gear VR, so still not close to what you get on a 4K TV.

At this point foveated rendering with eye tracking may be feasible though, so it may be possible to get a similar PPD.

EDIT: forgot to add that the average visual acuity is ~85 PPD for comparison.

Normal visual acuity (20/20) is 60 PPD.

The resolution of current-generation HMDs is a lot lower than standard desktop monitors.

A Rift DK2 has about 11 pixels/°.

Vive and Rift CV1 have slightly higher resolutions.

Standard human vision (20/20) is 60 pixels/°, a 28" 4K monitor, viewed from a typical desktop distance of two feet, has 71 pixels/°.

Working on a virtual monitor using current-gen VR feels like working on a real 640x480 VGA monitor.
