Oculus Rift and DCS World Discussion

[Corbett1403]

if the center was that much out of focus you would have seen it on test patterns/grids.

 

As Stated on Oculus Forums, You likely aren't focusing and wearing the HMD Correctly

 

 

 

Hope this is the case

[Warthog_Farmer]

I have aligned perfectly on the IPD axis... And yet vertically it doesn't matter where it sits.. High on cheek or low on cheek.. It's just illegible.

 

It happens on any game where there is small fonts. Exact same effect in Elite.

 

I can't think of any other way to wear it. Sit it high, sit it low, tilt it a bit this way, tilt it a bit that way. It's not hard to figure out all the options as to how you wear it.

 

As I have previously said I have it sitting in the small area for optimum clarity (as much as you can get). It is very noticeable and obvious if you're outwith this window.

 

I've had my friend over today who has confirmed what I'm saying through my rift, and another member on this forum verifying it.

 

The smudging to reduce SDE seems to be the most logical right now. I can guarantee it is nothing to do with fitment and it's pretty saddening. I'd love A little more SDE to be able to read things clearer. I can only imagine the MFD and HUD will be a nightmare with the 'intentional blur'

[KLR Rico]

My subjective opinion on it is that it's not really "blurry" in the center, just a little softer, but it is indeed easier to read text at the edges of the FOV.

 

I'm thinking it's a side effect of the distortion techniques used to match the display and lenses, since the pixel density won't be the same across the whole image.

 

EDIT:

Something like this, there's more pixels per degree at the edges than the center.

 

This thread has a discussion on VR distortion techniques: http://www.mtbs3d.com/phpbb/viewtopic.php?f=140&t=15417 (and it's where I stole this picture)

I'm still drinking my coffee so I can't wrap my head around all of it yet, but I think it's on the right track to understanding the issue.

Seems daft to me that you can see stuff clearly if you peer over into the lens yet looking straight on its blurry.

Looking thru the top of the Oculus Lenses is prolly the Equivalent of Looking down thru the Reading Part of Bi-Focal Glasses.

 

Only Time will tell,

The PPI would be less around the edges of the image.

[Warthog_Farmer]

Yes the PPI is less and even then it appears clearest. That's the main reason for my disappointment. The screen resolution is good enough - it's just the lens isn't up to scratch...

[KLR Rico]

Judging from the diagram, the PPI (or in this case, pixels per degree) is highest at the edges. No?

I had a couple of beers and couldn't really understand the diagram :megalol:

 

It was my understanding during the development that they would be warping the peripheries more than the middle to keep details central and and the slight blurring at the edges... That's what I put the colour fringing down to with the DK2.

 

After more testing this evening I can pretty much confirm it isn't possible to gain the same clarity. There is a fairly large sweet spot where clarity is pretty much consistent and then a much smaller sweeter spot where it is at its best. Even at this it is not possible to get the crispness you can see at the edge.

 

The rift is still great for other games so don't be too disappointed if you're waiting.. And for flying in DCS it will be very immersive. But for any aircraft where you're interacting with the cockpit, MFDs and need to see details on the HUD it may prove to be a little disappointing as I can't see it being this generation which nails it.

[KLR Rico]

The way I understand the diagram, is that each wedge is the same angular size, but the wedges on the far left/right cover a larger area of the line (i.e., display).

 

I also noticed the same sort of sweet spot behavior. There's like a 2 mm tolerance to get the absolute best image, but like 5-10mm where it's acceptable.

 

That brings up my next point, I'm kind of on the fence on how comfortable this thing is. If I want to keep it on that super fine sweet spot I end up making it fairly tight, but then it gets kind of uncomfortable so then I loosen it back up some. Then it eventually moves out of position, and so I wind up fiddling with the damn thing every 30 seconds. #earlyadopterproblems :D

[Warthog_Farmer]

That exact same thing. Everyone else comments how comfy it is... But I don't think so either. Not with the accuracy required. Good news is the tracking is, once again, pretty sweet. Just need resolution and clarity to catch up for Cv2

[Corbett1403]

Then I wonder if the vive has the same issue with the blurring effect as most of need to interact with cockpit and seeing the hud and mfd's is vital I just wonder what the difference is between the two.

[louisv]

As there are 2 of us here with the same issue i don't think it's isolated. We need more CV1 folk to test it.

 

Look directly at the switches in the Apollo module (which are much like cockpit switches in the jets we fly) and you'll struggle to make out the text for the switch (APU GEN, MASTER ATM etc). Keep looking at the switch with your eyeball but tilt head forward and the font becomes much much clearer and legible as it is viewed through the extremities of the lens... Like a teacher peering over the top of her glasses at you.

 

It really is a deal breaker right now for me as I can't imagine how developers can work to that limitation very well.

 

Don't panic.

 

You can try the same thing with ordinary rimless glasses, its a diffraction effect ( ref: Fresnel equations of the near field) or you can compare it to a pinhole camera, sort of a side of the pinhole.

 

Objects through a pinhole are always all in focus, there is no depth of field at all. Fresnel is the same guy as the lens. Brilliant french physicist 19th century, he would experiment with drops of honey, he could not afford lenses !

 

If you wear rimless glasses look at something from the top rim of your glasses and you will see on the defocused rim that the object is now sharper.

 

Prediction: This effect will be identical with the Vive.

 

The important point is: it has nothing whatsoever to do with the quality of the optics.

Forgot rimless

[DerekSpeare]

I'm reading on the iRacing forums from one new recipient that the image is the clearest at the center :/

How weird maybe they have it setup different or there is a problem with some rifts

[SkateZilla]

so far everyone is seeing this issue is using the Apollo 11 App, maybe the FoV setting they use in the rendering.

It also happens for me with FlyInside/P3D.

[DerekSpeare]

Below is what one new CV1 user has posted to the iRacing forums about his immediate experience with the device:

 

Good:

1. Brighter Screen

2. Centre well focused once setup

3. Red is clearly better (no longer looks really low res and not in the same 3d plain)

4. Refresh rate makes it feel lag free (with time warp etc)

 

Bad:

1. Refraction glare from lenses is very noticeable and distracting

2. FOV makes you really feel like you are wearing something around your eyes (ie the outer edge limits are clear to be seen when looking forward)

3. I have to set my IPD at 67-69 to get it into focus (im about 64 ish)

4. Anything not immediately in front of you is slightly out of focus so moving your eyes around highlights this

5. also there is some colour separation aberrations in the outer section of view too.

6. Distortion in image not in the center (moving your head around you can see straight lines bending)

(emphasis added)

Aside from the slight effect of text sharpening at the edge of FOV, I think the focus across the entire FOV is pretty even. Personally I don't notice much distortion or variation of focus across the whole FOV, unless I'm really looking for it. The lack of peripheral vision is noticeable though, it's pretty much like wearing a scuba mask.

[Corbett1403]

All this talk about the bad things on the rift is making me think I should cancel my order and get the vive

[louisv]

Don't do it.

[Corbett1403]

Don't do it.

 

 

 

You think the rift is much better

[SDsc0rch]

be a man and stick with your decision

[Corbett1403]

Done I stay with the rift thanks guys

[dot]

I'm really hoping for 2560x1440 rgb screen upgrade for DK2.

Done I stay with the rift thanks guys

 

You can always return the unit, or sell it if you are not happy with it.

 

P.S. I mean you can return it within 30 days.
