Oculus Rift and DCS World Discussion

[bongodriver]

No, what they are saying is that the screens used must have refresh rates of at least 90hz to give the best results for low persistence, nothing at all to do with game fps.

[howie87]

Refresh rate is closely related to FPS.

 

75Hz just means the screen can display a maximum of 75fps.

 

If you have a 120Hz screen at 60fps, you wouldn't see a difference between it and a 60Hz screen.

 

Low persistence is the ability to illuminate a pixel for less than the duration of the entire frame to eliminate smear.

2K is 1080p

 

Yeah, my mistake... I misunderstood what a friend was telling me. Will edit my post. Thanks Skate

 

 

Oh and saw this in my twitter feed from Dslyecxi. Not entirely sure how accurate it is and/or if it has been posted before http://vr.mkeblx.net/oculus-sim/. Its a simulation oh how it looks through the Rift. Mainly to show screen door effect and blur.

 

From what I hear the motion blur is a little over exaggerated but the screen door is pretty accurate.

So do you think Oculus are completely overlooking this and are at risk of falling flat on their face because nobody has the hardware to run their new toy?

It means that they want to convince everybody to use simpler graphics instead.

 

When making something for the Rift it is important to remember that fast rendering with simpler graphics always perceived by the user in a better way than beautiful graphics which doesn't render 60 times a second in a persistent fashion.

 

If you have stutters that makes you vomit it's worse than if you have much simpler shadows in the game, in this sort of sense.

 

P.S. I'm very curious how ED will solve this with DCS. It basically should never ever drop frames, not by bomb exploding, not by smoke, not by flares popping, it should be smooth as silk, preferably at 90 FPS or higher.

We have been warned:)

 

EDGE will support Quad SLI/Xfire

I hope this isn't true, but reports are saying Facebook has purchased Oculus VR for $2 billion.

[SkateZilla]

It's legit.

Holy Crap!!! I'm not sure how I feel about this,any thoughts??

[maddabboyahoo.com]

Yeah I think a lot of people think it will have to render 1080p(Dk2) or 1440p(hopefully CV1) for each eye when in reality it is rendering half that per eye. That being said, on the current engine I get 50-60 depending on what is going on(with 1 viewpoint @1440p)... Well I do get lower when looking through the TGP at towns with AI in them.

 

I wonder if low persistence will help with the lower framerate or at least the stuttering.

 

Edit:

Oh and rift doesn't do 3d like a 3d monitor where it needs the high fps to alternate the images. But from what I am hearing you need it for less motion sickness.

 

One day (long time I know) I think it would be cool to see DCS in 8k/eye @240hz :)

 

Yeah your only rendering a total of 1080p or 1440p for both eyes but rendering two cameras in games essentially halfs your fps. For me it's been just like rendering to a 3d monitor but with lower resolution. The resolution isn't as big a deal as the 2 renders for stereo. Optimizing that will help alot.

This is not correct

 

They are using new OLED very quick blank screens for low persistance to have sharp images pulse at you very quickly. 2ms-3ms pulse of image then black. The 75 and up refresh rates are for fps they want it matched and they want vsync with no tearing.

 

If you have the SDK you can read all their notes and discussions on how best to create content for the rift. They definitely want very high fps with zero latency to create an environment that is perfectly in sync with your heads motions so you don't get sick. It's all the minor discrepancies from reality that are making people sick so they are tackling and trying to eliminate all of them.

 

If you're getting only 30fps and your pan your head fast with a high speed OLED screen your going to get big time strobing in your motion. With a quick head turn you need high fps.

The blur should be gone in DK2. I think the screen door at this link is assuming screen size stays constant and only resolution changes.

 

They wanted DK1 to be 5" diagonal. They shipped 7". Now DK2 is closer to 5" and is 1080p. So you've got more pixels in a smaller space. Both increase resolution and help with screen door. I think DK2 will be significantly better than it looks at this site. I think if they get to 1440p it will look way better than this site.

Not sure what the problem is... Or am I missing something.

[RogueSqdn]

Think about being required to have a FB account with your real name attached to it to use the product, and how much further that line of thought can take you....

 

 

I deleted my FB a year ago because I don't trust them and haven't looked back.

Damn, I so wanted to see an IPO from Oculus.

I would have been all over that lol. But the cat is out of the bag now

[cichlidfan]

I would have been all over that lol. But the cat is out of the bag now

 

I would still like to know the details of the transaction (cash, FB stock, etc.).

[blksolo]

I think they got 450 million in cash

[Raven68]

Seems like this device DOA now according to a lot of comments on FB.

[BIGNEWY]

Anyone feel like Mark Zuckerberg's announcement is like something from tron, I could just picture him stood in front of a crowd giving a crazy man speech

 

 

Kevin Flynn - The Grid. A digital frontier. I tried to picture clusters of information as they moved through the computer. What did they look like? Ships? motorcycles? Were the circuits like freeways? I kept dreaming of a world I thought I'd never see. And then, one day...

 

 

I am not sure what to think, but he seems to of made a promise about the gaming side of things which is good

 

Immersive gaming will be the first, and Oculus already has big plans here that won't be changing and we hope to accelerate. The Rift is highly anticipated by the gaming community, and there's a lot of interest from developers in building for this platform. We're going to focus on helping Oculus build out their product and develop partnerships to support more games. Oculus will continue operating independently within Facebook to achieve this.

[bongodriver]

Well let's hope they are truly invested in making this a gaming success, I say some development grants to flight sim developers would buy back some of my trust.

Just consider the source.

[blksolo]

I think all the negative comments are from fanboy's (myself included)being heartbroken that they sold to facebook. They will get over it in time. After I calmed down I think this is definitely in the best interests of VR. Who wont take Oculus seriously now? Also the PRESSURE to put out a killer product is even greater,you dont get 2 billion dollars to put out something that is garbage. Now people like NVidia and ATI will have to kick it into overdrive to make more powerful graphics cards cheaper if they want a part of the billions of dollars facebook will make from this.I think this gives Oculus the time and resources to put out a much better product than they would have without facebook's support.
