Oculus Rift DK2 Thread

I'm sorry, no idea how everything works (yet): Is the FOV a hardware- or software-limited thing? Well, certainly both but I'm specifically refering to the DK2 "issue" from within the last page.

Hardware related. I'm thinking we won't see anything past 110 FOV unless we use curved screens or foveated rendering.
 
Yea I could tell the FOV was just a bit less. I'm someone who used DK1's A lenses pressed up as close as possible, so I did notice the difference. But it's not huge. And all of the other improvements outweigh it IMO.

I'm curious, what are your specs and what kind of performance are you getting with demos?

I guess a lot of people are just jumping to conclusions.

How many of us actually have both devices right now?`

As a long-time DK1 user, the biggest issue was blur and image clarity (and lack of positional tracking: nausea everywhere).

I could sacrifice a bit of FOV for that.

Can't wait to try for myself in a couple days/weeks.

Oculus should investigate some kind of AmbiLight type solution to lessen the effect of the reduced FOV, detail is lost at the extreme of peripheral vision anyway and something like AmbiLight could increase the immersion factor much better than black bars of any sort would.

That's actually a really good idea! Is there a way to stretch the image towards the edges and keep the resolution the same but increase the fov?
 
So what are the must have new demos to download?

Do I need to install the .4 SDK first (its SLOWWWW)?

Have any Steam Oculus games been updated?

GTX570
i52500k (OC'd to 4ghz)
16GB ram

So far pretty darn well, but most of the available demos aren't demanding. I still haven't ran Technolust, Couch Knights, or Elite or anything that graphically intensive. But performance does seem smoother than the DK1 and I was surprised how well I've been able to run most demos at a silky 75Hz.

Things are so much clearer when looking around now. Low Persistence is soo smooooth. FAR distant objects can become a pixel mess but the range of discernable detail is so much wider.
 
My UPS tracking page just updated. It's being shipped from the UK and the scheduled delivery date is August 5. Too bad, I hoped to get it before the long weekend. :-/

I'm curious what kind of performance you'll get with Technolust once the deferred shadows issue is sorted out. Your post gives me hope, I'm still running on a 7850, that while slower than yours, is almost on par. I'm surprised to hear performance is smoother than dk1, is this due to the time warp and/or low persistence? I'm assuming you were running on those specs for dk1 as well.

Yea same rig for DK1. Not by much, but it honestly might be because of the slightly lower fov. I was usually running DK1 demos at 1080p for a bit of supersampling anyway. Plus there may have been plenty of demos I could have run at 75Hz on DK1 but that just wasn't possible.

From Reddit:


Kind of a bummer. I had a DK1 for a year and I loved it but I decided to sell it while I could still get some money for it. I kind of regretted not ordering a DK2 but I'm starting to think that waiting for the consumer version wasn't such a bad idea.
Click to expand...

Reading this last page, lower FOV is crazy, it's weird that DK2 turned inferior than DK1. and how this will be good for testers and devs? What were they thinking?

Lets hope they go back to DK1 fov and even increase it with CV.

I'm extremely excited for Technolust. Hoping my 2600k can keep up. Thursday cannot come soon enough.
Click to expand...

My number one most anticipated full title for the Rift bar none. That first demo after a year of using dk1 gave me such a feeling of immersion. Looking up at the skylight and watching all the cars fly by, watching the shadows move around the room and seeing the blade runner billboard outside, such a wonderfully realized world. I'd love to have an environment like that as a virtual hangout with friends in vr.

Finally! Switzerland, 09:12 AM and now it's finally on the way. Left UK today.
 
What the shit now I'm even more confused, just got my shipping notification, label was made 3 days ago but the only update is: Processed: Ready for UPS 3 days ago. What the hell is going on UPS...

EDIT: Oh and those eBay prices, damn nearly makes me want to sell...luckily I can't sell internationally.

Yes it is! Did you walk into that tiny little dark room? Was so eerie being inside there looking back into the rest of the ship. Then it was even scarier when I fell through an opening out into space LOL
Click to expand...

Unfortunately that demo took a toll on my card and I can't run it at 75fps in the main room. However, staring off into space in the black room was magical and I felt a tingling sense of not wanting to step off the ship. So, so close to the feeling of presence.
 
I asked earlier but I don't think anyone mentioned it -- the DK2 has latency testing built-in, instead of requiring an external device, correct?

Do any of the demos (such as Tuscany) use the API to provide a hotkey to bring up a latency overlay? I'm interested in what kind of numbers are produced, how cloned / extended / direct HMD (head-mounted display) compare, etc.

lol yea it's like a drug. So clooooose to that magic of sustained presence...

I'm definitely upgrading my card real soon. I want to hold out and splurge on an 880, but its so hard to know that Elite is just sitting there ready to be experienced with the DK2...
 
Just got an e-mail that the Vanguard Valkyrie Kickstarter is now on hold due to an IP dispute. Weird. Never got a chance to download the demo after backing so that kind of stinks too.
 
Woke up this morning to my dad telling me I received a package. He set it on the bed and I turned it over to see it was my DK2!

...Then I woke up for real.

This morning TWICE I dreamed I was in an airplane, which started tumbling, nearly crashing, maybe avoiding a mountain, then speeding into a wall or mountain. Then I woke up both times, right as I died.

Over the weekend, more Rift-related, I woke up Sunday morning to someone hammering on my door. I stumbled to the door, found a guy holding a square package...Sunday delivery, what on earth?

It turned out to be an honest person in my apartment complex and my Wii U pro controller and 3DS XL case had been delivered to the wrong address, and he was just dropping it off. :P
 
I just read that the optimum distance for the camera is on top of your monitor and 5 feet away.

Who in the hell has their desktop monitor 5 feet away from them?

I have the same problem. I sit maybe 3-4 feet from a wall. I also have 2 monitors so there's not really a place to put a camera on top of one of them. I'm not sure how I will manage it.

I tended to back my chair (or my self if I was standing up) away from my desk a few feet when I had my Rift on to avoid knocking stuff over.
 
You don't need to have the camera on top of the monitor, or alternatively you could (perhaps) move the monitor away as you don't need it close when you are using the Rift

Yeah, that freaked me out! How do you man the turrets? Pressing F doesn't do anything :(

Grats, I guess Lach's DK2 is on its way as well now or will follow soon. ^^

3 DK2s for Switzerland! :D
Click to expand...
I suppose so :)

My friend in Basel got his shipping confirmation too. My problem is that I work on Thursday. They will probably leave me a note and I will tell them to deliver on Monday :/

I would love to play the whole Friday with it...

Crazy, as I finally got the old DK2 version working today (0.4 compiled version never launched) along with a bunch of other 0.3 sdk demos.

I don't even use a monitor lol, have been using my pc hooked up to my plasma tv for years. Actually a bit concerned how I'm gonna wing dk2 with the much shorter hmd cord. Gonna have to get creative with my setup. The camera would have to be placed at waist level (while sitting) if using my tv stand. Might have to use some duct tape! Speaking of, how long is the cord for the camera?
 
Finally caught up on the thread.

There are some concerns but let's come back to earth, things still sound great and the kinks are being worked out. This is kind of unprecedented for consumers to be able to buy these at this stage in dev. The unit isn't fina.

I understand that, I wasn't expecting the dev kit to be without issues. I was just surprised and disappointed that one of the big initial issues wasn't even talked about beforehand.

Basically, this:

What I find strange is nobody reported this while playing EVE the past few months. Hundreds if not thousands of people gave it a try, and I didn't hear anything about this smear.

It is really strange that no one seems to have mentioned it. It could just be not that noticeable, who knows.

Still, I can't wait get my hands on the DK2.
 
Palmer response to FOV debacle.

Via Reddit:

its a poor trade off to reduce the FOV for render speed.

It is a poor tradeoff, and one that we did not make. The lens design was driven by hard limits in optics technology, and we already had to make tradeoffs to get a large exit pupil/high FOV/flat field curvature/longer eye relief out of the smaller panel in DK2 (increased chromatic aberration in DK2 is one example, luckily we can mostly correct it in software). As Brant already said, the rendering improvements were a nice side effect, not a driving force behind the design of the optics.

Aside from that, note that the horizontal FOV of DK2 is actually very similar to DK1 (most of the "loss" from 110 to 100 is a result of the aspect ratio change, and is mostly on the vertical/diagonal). A lot of the perception around it having a smaller FOV is a result of the DK2 lenses being significantly larger than the DK1 lenses, allowing the user to see the edges of the display even with the same field of view. That is one of the reasons our default settings feather the displayed image out to black over ~10 pixels, it makes that edge less apparent. We could have designed it so that the lenses were the limiting factor, as in DK1, but that inevitably results in wasted pixels and reduced FOV for most users.

Another Palmer response.

I hate it too, it is a terrible measurement. We initially used it because we need a spec to compare against all the other HMDs on the market.

In terms of horizontal FOV, DK1 and DK2 are actually comparable (And DK2 has more stereo overlap, as well). The aspect ratio change means that even with similar horizontal FOV, the vertical/diagonal are still lower.
Click to expand...
 
More responses from Palmer lol.

Because it is not practical until you get extremely wide FOV bordering on the limits of eye rotation. Stereo rendering is costly at any resolution, adding an additional two camera views on top would destroy performance even at very low fidelity. It is less costly to do two full-detail renders than four renders of varying quality.

This is especially true within the limits of current HMD hardware - the high quality area would need to fill most of the FOV to avoid being able to look directly at low quality areas. It would make sense if the total FOV was over 180 degrees, but that is a long way off.
Click to expand...

We did not reduce FOV for performance reasons. It is a side effect, not a cause.
Click to expand...

The FOV of the RiftUP mod is much lower than DK2.
Click to expand...

You are right that the space at the top and bottom was not used, but it did completely fill the lenses vertically, even with a theoretical eye relief of zero. The same was not the case horizontally - the black center divider is easy to see in DK1, DK2 has greater stereo overlap and nearly equal HFOV/VFOV.

Nice to see the founder responding.
