SDE comparison (Macro) - Guess the VR headsets!

[michaelnyden]

Most actually do need slightly more because you lose some to where your computer is versus your play space and going to the back of the computer alone takes up one meter unless you turn your tower backwards. I would say 7m is the minimum most people need to a 5x5 space to have excess and not pull on things when you get to the extent of the space.

@generic

You got your Reverb issues solved?

Nope, but the tape at least keeps the cords together

@Davobkk

The difference between original 8K and 8K+ is surprising. Can you tell us honestly how much harder it will be to drive the 8K-X? Will we be able to play Elite Dangerous with acceptable frame rates?

From the tests Ive done so far, the 8KX is very forgiving for lower resolutions. You can easily run it on something around 3000x2200 and still looking great. You will start to get some aliasing in sharp edges of course, but thats another problem.
On default, the 8KX has a resolution of 3800x2400 something (will check the exact numbers tomorrow) . In other words, its not more demanding at all compared to 8K+ or 8K.

I must add that 8K+ also looks good on lower resolutions. The scaler does a better job than on the 8K.

Marry a rich girl that likes VR more than you do.

Or just marry a rich girl Which I didnt…lol

@JoCool

Allright! Cancelled my plans on Amsterdam, will see Pimax in Berlin. Much easier that way!

You should come to VR Days anyway if you can, its really a great exhibition - one of its kind!

@eileiksis

I will come to Berlin. Good work Sweviver and especially Pimax. They reached their goals. I enjoy playing Wildlands in 3D and Bolivia is wonderful to see in the 5K+. Could you please take through the lenses pictures from objects in high/very high distance? The SDE of the 5k+ is sometimes annoying.

I will update you more about Berlin soon!
More SDE tests coming!

@Ludiks

for some reasons explain how the 5k+ have decent SDE but huge pixels, with a 8k that have more but more space because of the pentil, it explain how on the 8K small things away got soft and better and on the 5k+ the sharpeness of every things that can be fully displayed.

The pentile matrix on the old 8K made it look worse, even if the SDE was better. It didnt have 3 subpixels per pixel. I think I explained that in the 5K XR OLED video long ago.

@kellerbach

In the comparison with the female head between 8k and 8k+ you can see the 8k strong aliasing. I generally notice this with my 8k in many games, that I don’t get it removed.

Yeah the first 8K had less subpixels (diamond pixel matrix) and it was very obvious. The pixels were also round instead of “lines” like RGB matrix has, which is the reason for the color fringing.

@generic

Pimax is more of planning, being overly enthusiastic and sucking at communication.

At least they keep pushing the limits and provide us with the most innovative headsets in terms of panels and lenses - and still way cheaper than a Bentley.

@RobCram

I like the 8KX colours compared to the Reverb which show better black and overall colour, but not sure how accurate the text images are as they don’t look anything close to that in my headset. Not sure how much different a V2 Reverb would be against your V1 @SweViver. Very interested in the 8KX now but would like to see more examples and hear some hands-on impressions first. Thanks for posting.

It would be nice if you did comparison of the DCS cockpit as well.

I suspect my Reverb v1 has its flaws. On the other hand, I wonder why didnt they (HP) respond to me upon 2 occasions I tried to contact them about all the flaws. I gave up on them long ago and cant care less aboout a replacement… I dont use that headset anyway more than just for comparison.
Btw check my new video

@MReis

That is very interesting - some details, like the “waves” of the paper photographed are totally lost on the reverb.

The “waves” is just “Moire” effect created by the camera, due to the lenses. Its an optical thing. Happens often when I try to align pixels straight to the cameras sensor. Nothing you will see in VR anyway, its just on the camera.

@spamenigma

I think some of this has been asked already but it would be very interesting to see these compared to certain earlier HMD’s just for fun. Vive, Vive Pro, Rift, Rift S, Ody+ if you have any of those to hand and have the time and inclination to do so At worst at least the OG Vive.

Yes I have that included for upcoming videos

@MReis

If you Makro enough then even the pixels of real life will be visible like that ( molecules and atoms, or quarks, Photons and so on). It’s the comparison that matters

Holy sh*t I gotta try this! hahaha

@RobCram

JFYI the V2 Reverb comes with a clip/cover to keep that section together.

Woah! Thats a surprise, I had no idea actually. No wonder. That connector is useless. Randomly disconnects even when sitting down.

@michaelnyden

Please see if a quality 2m extension cable will work with the 8kX, that is holding back most room scale players from this headset vs the 8k+

I will try soon. Only got 3m and 5m and they caused a black screen. But its cheap ebay cables…

@VRGIMP27

Great pictures @SweViver. I am actually pretty impressed by both tbe 8K X and the 8K+. For an HMD showing about half the raw image data of tne 8K X the upscaling on the 8K plus is very decent.

Thanks Check out the new video “teaser” on my chan!

[MReis]

Thanks Essenz sure if it’s the lenses or actually photographed Text. Thx for pointing it out.
I guess an Makro Lens for a camera doing that might just be a bit on the expensive side .

Yep, I see the dot haha. Crazy stuff!

[Skidrow]

Yes but most dont have 5x5m play space, 2-3m play space i would say is somerwere in the midle.

[michaelnyden]

Most don’t have 5x5 but also many have their pc 2-3 meters away from the outer edge of their play space. ie. they have a couch in the way that borders their space and then the desk/office area is beyond that, when you add this up the far edge of the play space away from the PC tower might be six meters away, hence the reason why you see so many online looking for 2-3 meter extensions for their headsets.

[SweViver]

My space is barely 2.5x2.5m But Im using extensions when possible anyway.

[michaelnyden]

Yeah nobody wants to be tugging on and at the limit of the cable, extensions give a nice cushion.

[geoffvader]

my play space is only around 2m x 3m, but my PC is in one corner just outside of that so with the standard pimax lead I am constantly feeling like I’m going to trip over the cable, which I never got with the vive because of the link box.

my PC is just over 1m off the floor, plus I am 1.8m tall, so thats 3 of the 5m already taken, so I can only be about 1m away from my PC before the cable starts lifting off the floor and becomes a trip hazard which is really not great when I can’t see anything going on around me, it definitely needs another 2-3m to be comfortable

Colorfringing is not what I mean. I mean clearly worse anti-aliasing. Was in the comparison shots (8k vs 8k+) with the woman’s head the same SS and the same ingame antialiasing?
