ED and the Oculus Rift Developers Kit 2 (DK2) Discussion Thread

Ya that's why I said offset the images. It's the same image just offset a bit.

At least that's how stereoscopic used to work.



The Rift can (and sometimes does use) off-set images. This is usually done by games that add Rift support in later on. However it really isn't very good, whilst it does give a degree of 3D, it doesn't give much sense of depth.

You really need two different images, because each eye sees an object from a slightly different angle, and this means the image needs to be rendered from two different cameras.

This give far superior results to simply off-setting a single image.

Ah! I stand a bit more educated. Having never used a rift, I was wondering how everyone was having such an amazing 3d experience. This explains a lot. I was under the impression the Rift simply offset the images like days or yore.

Thank you! More excited than ever now.
 
Thank you :smilie:

i think my order is due to arrive in August or a bit later maybe as i probably missed the initial order window.

Better late than never though :D

Yea, I ordered mine roughly 5 minutes after I got access to the alpha 1 as a premium beta backer. I will never forget that, because it was roughly like this:

- Switched my TV on, which is also connected to my computer and placed my seat rather close to the screen and turned up the volume on my surround system
- Launched the game
- In waste disposal flew past an asteroid
- Thought: "Holy ****! This is what immersion is like? No game did THAT to me before in this way!"
- Drifted past the next asteroid.
- Quit ED and placed my DK2 order


Edit: Will get mine in August, too. (unless by some miracle Oculus manages to produce faster than they thought or thousands of pre-orders don't have the money when shipping starts)

Edit2: It should also be stated, that the image offsetting thing done for "some games" is only available in unofficial drivers AFAIK. From the official side that's not even considered to be an option, but those who made the unofficial drivers implemented it as a hack for games that cannot be forced to render two views for whatever reasons. (That's from my memory. Please correct any misunderstandings I have. ;))

I ordered my DK2 on the 19th of March, so I am hopefully among the batch that receives their DK2 in July. However, with transportation from the US to Norway, I expect a week in shipping.
 
I'm actually trying to cancel my preorder of DK2... there's no way I'll be able to power it for ED :(. At E3 we were using the HD prototype, which looked amazing but was powered by two GTX 770s; I have one 660. I'm sure DK2 will be yet more demanding.

I hope to get OR someday, maybe after my next PC upgrade. By the way, I got to show off ED to Palmer Luckey and the OR crew at E3; it must have been a word of mouth thing, because otherwise the big cheese would have had a private session with DB :)

Sorry to hear you cancelled your order :(
But cool to have shown Palmer ED ... What did he think?
I have to confess to just splurging 2500£ on a new rig to power my DK2 with ED!
Must be mental!

Got a reply from David that he was using a titan to power the DK2 they got to test at 75 fps, so opted for a rig using a 780 ti. Not quite as hardcore but should work fine. :)

Whooah there!

That's a pretty big thing to forget about until now! :)

What was Palmer and the rest like, and what was their reaction?

Come on man, you can't leave us hanging like that! ;)

More info please. What was their response, etc?
 
Does anybody have videos of Premium Beta and DK2/"Crystal Cove" in action? I want to see how translation in the game looks like.
 
I was actually very surprised if Palmer kept talking about other games, and completely failed to mention elite. Maybe just hadn't seen it, I suppose. That is extremely unfortunate because it would have generated a lot of PR
 
Each eye is completely different, as the image is struck from a very slightly different angle. Our brains use that slight difference to determine depth, and are ridiculously good at it. This means essentially that two separate camera angles need to be rendered and then composited together.
 
Managing expectations

There's some things to be aware of relating the DK2 that you should know so you aren't disappointed when you get it.

It has a lower perceived resolution than the HD prototype. This is due to the subpixel arrangement. It's a pentile display so there are less red and blue subpixels than standard RGB. The resolution is higher than the DK1 if you've tried that but if you are expecting things to be as sharp as your 1080p TV or monitor you might be underwhelmed.

There is still a Screen Door Effect. This basically is like looking through a thin mesh and is due to pixel fill rate (space between pixels). Due to the pentile subpixel arrangement it's different to the square pattern on the DK1 and HD prototype and some people have said it's less noticeable. After a while you'll stop seeing it without looking for it but it will probably be apparent when you first use it.

The screen is in portrait mode. The screen in the DK2 is basically a phone screen (Samsung Note 3 so evidence suggests) so it's pixels refresh top to bottom in portrait mode rather than landscape. This means that the pixels refresh left to right (or Right to left) in the DK2 so there are synchronisation issues between the left and right eyes. I don't know how big an issue this will be but nobodies noted it an any hands on impressions I've seen.

There is a known ghosting issue. Ghosting is where you basically see an after image when you turn your head quickly. Oculus know of it but were unable to fix it for the DK2's production. May get fixed by a firmware update if we're lucky.

The optimum experience with the DK2 is games at a constant 75fps(it supports 60hz, 72h and 75hz). The reason for this is two fold. One of the awesome new additions to the DK2 over previous iterations is low persistence, which is turning the pixels on for only 2ms and then turning them off. This reduces smearing of the image which is said to be one of the major causes of simulator sickness (feeling queasy). A high frame rather also provides a lot smoother experience which looks great and helps reduce nausea. A constant frame rate is important because if it drops too low nausea may set in and you may experience flickering due to the low persistence.
Due to this requirement for high frames in side by side 3D at 1080p this means you will need PC umph for the better looking VR games (like E: D) more than you would for just running 1080p at 60fps (old and simple looking games should run much better).

Weight, it's heavier than the DK1, not massively so but a small amount. I only used the DK1 for relatively short periods and was fine so I dunno how this may affect long play periods (a DK1 owner could maybe comment). You may have to keep adjusting it if it slips

It's a dev kit. Pointing out the obvious but be aware that the DK2 will require much more faff getting it working well and you will face uphill struggles at times. It will not just be plug an play.

If you are thinking of getting a DK2 then be aware of the above. It may be worth waiting for the consumer version as it will probably fix/reduce all the above and then some.

Saying all the above I cannot wait for my DK2, ordered it as soon as I was able to, July can't come soon enough. After playing about with a DK1 I could see that this was the future of gaming and I wanted in! :)

Weirdly enough, that was my reason for placing an order for a DK2. I thought that the CV1 specs were going to even more demanding. I do want VR and I'll be happy to hobble along on lower settings until the price for the videocards designed with VR in mind are released and have come down to a reasonable price.

My own VR might end up resembling Atari Battlezone for a few years :)
 
DK2 might not be a panacea, but it''s a heck of a lot better fix than nothing waiting for the CV1 with an unknown release date so far - which I also do intent to get when it comes out.

As for framerates, most of the issues with xfire/sli I've read about are on previous driver releases and should be mostly fixed / minimized by now and once ED supports them a pair of high end HD 79xx or R9s (AMD) should be adequate at this stage.

Besides, it will be interesting to tinker with the kit and other demo to see how effective the kit is.

;)

I think they were pretty impressed, but to be honest I couldn't understand a lot of what they were talking about :p! They were giving it a real test, analysing the different layers of effects etc, one shook his head really violently to get it to black out, though to be honest if I shake my head really fast I can black out too :p.

Oh it'll be great. My post was just to manage people's expectations, better to go in knowing what it'll be like than expecting something it's not and being disappointed.

SLI/Xfire's only benefits if you can't currently hit the max FPS needed on your card.
Quote from Oculus
"Dual GPU will increase the FPS, but not necessarily shorten the latency. This is because it will pre-render frames. So your FPS may double, but latency would stay the same (or even increase depending on the settings). In some situations, this could still be beneficial, for example if with a single GPU you were getting FPS less that the refresh rate. If you are already safely over the refresh rate, then dual GPU will not help at all.

In almost all cases, it is much better to get the best single GPU you can afford, rather than going dual GPU (especially with lower or mid range cards). If you already have a card that is not the top of the line, then sell it and get a better card. However, if you already have dual GPUs, they can still work and be OK (just not optimal)."

I hope someone videoed Palmer or others from Oculus testing/giving a positive reaction to E: D.

Post a Youtube link to that on Reddit, and you'll have thousands of extra backers instantly.
 
Some people are saying they are getting them in August, how do you know this. My order just says Pending awaiting inventory, no mention of a date anywhere. I ordered mine on 1st April so not too long after the pre-orders went up.

Because the website says orders placed now are expected in August. When first opened for orders it said July. Don't know when new orders are expected to ship but, previously there wad an estimated month of delivery.

Here's hoping.

The (now) was said during an interview on E3 but also the first batch will be send in juli
So who knows what todays now mean except you're being in line.
The consumer version won't be rushed acording to mr lucky .excuse me if that's spelled incorrect :p but Facebook buying oculus gave them air to development so the consumer version won't have anything of the DFK's in them so he said.and they will be released when he thinks they are ready. With the fear of former failure of VR in mind.
So I expect we will gett to enjoy our DK2 for quite some time.

I also hope there will be a linux version of ED... if I can believe the articles about Microsoft on e3 &Xbox ,the steam machine and others predicting a rise of Linux games.
So please mr Braben I know you know its a better platform, talking to the student in you..
:)
