Oculus Rift and DCS World Discussion

[hansangb]

Their forum said that that number is randomized so that people will not guess when they will be next in line.

 

 

Did anyone already get a full charge vs 55$? I was under impression that first they charged 55 and then when shipment ready, they would charge full amount.

 

I was just charged $50 and not $55.

Based on tomshardware charts and other benchmarking charts we are in big trouble with the RIFT and compute power.

 

I'm thinking an full desktop 135watt i7-4core and (2) SLI 770's are going to be the minimum to make the DK2 work smoothly with all games and everything turned on. That should get 75fps in most games in stereo 3d at 1920x1080 with it all on.

 

But I'm thinking if they goto 2560x1440 for consumer then even (3) 770's SLI or even (3) 780's might not be able to do it smoothly with all the goodness on.

 

Time to start saving for many GPUs and a new desktop gamer.

Ordered straight away.

 

I'm kind of a developer (cockpits etc), that's my excuse and I'm sticking to it ;)

What are you going to use the other 6 1/2 cores for? ;)

[hannibal]

other games... :D

 

btw, any word about EDGE and its core usage?

Mikey, I think you are getting this slightly wrong: as I understand it there will be increased demand for graphics in that the rift will have to render once For each eye but you don't have to have a system capable of running games at 75 or 90fps. That is more like the refresh rate of the rift, like current monitors can be 120hz but you can still play games at 30fps

[bongodriver]

still amazes me that some are getting this so mixed up.

Of coarse you can run it at low frame rates. But the specs for running in the rift really want you to be able to do 75 fps not to get sick. They want it to be solid at fast fps. That said I'm perfectly happy to play with my DK1 at 25-45 fps right now.

 

But at oculus they definately want game makers to create games that will run solidly at very high fps. I don't think they'd think a 30fps game was considered rift ready.

i get over 30 Frames per second running maxed on 2 viewports at 960x1080.

 

I suspect we'll have EDGE/DX11 Support before Rift is released, so I'm positive that a single Mid-High Tier GPU will run DCS on Rift fine.

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 :)

2K is 1080p

[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.

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.

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??

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.
