The bf109 e series has rectangular wings

Ah see, my lack of aeronautical knowledge again. So does that mean the 5k+ image is more accurate?

I guses so …
I guess I could recognizant the 109 in the 5k+ picture …
No way in the 8k one …

Like I said, it looks more like this.

An important question is were these rendered at the same resolution levels? It appears now from SweViver’s latest video that they probably were not as the PiTool sends a lower resolution to the 8K than the 5K+ at each setting.
Also, both units can probably render the aircraft better than pictured with higher resolution settings. At some point however I would think the lower native resolution of the 5K+ panel will reach a point of diminishing returns and the 8K will outperform the distance rendering. What we don’t know is the fps cost of achieving that on the 8K.

First one is possibly a plane, second one is possibly a duck flying the other way. For some reason both have the same name

This is all in Sweviver’s review. Use the comparison time link toward the end.

This is a test image. I’ll explain after with an edit.
EDIT: Hmmm… This was a test of whether Firefox is applying anti-aliasing to the image. It does. The original image was a 1440p screenshot in BMP format. When opening and magnifying the image there are significant jaggies. Some file viewers and editors also apply anti-aliasing. I made sure the image posted is the same as the portion of the original BMP. If you are not seeing significant jaggies, your IE is changing the file for viewing.
Trying to convert the file I also realized the changes to the image that can occur by editors. So that should be taken into account also when viewing images of the HMDs. The images are OK for some comparison purposes depending on how they are viewed but not necessarily for how the image in the HMD actually looks.
Just my 2 cents.
EDIT 2: OK, I downloaded the image and it is the same as what I uploaded. I use Faststone Viewer, no AA. Paint is OK. Photos does apply AA.
EDIT 3: Another observation. Almost everything we have for deciding which HMD to go with are stills or videos viewed on 2D monitors. Every monitor, unless properly calibrated will show things differently.
If one were to download my pic in this post and see the jaggies at closeup, they might think, “Wow, that’s horrible, how can he play like that?” The fact is it looks fantastic in game on my screen. There are no stills in game, things are moving very quickly and jaggies at that distance are just not seen. The same will be true of both HMDs whichever one we choose.

I ve seen in Sweviver’s review that you can detach the cable of the headset, I am wondering if it could be possible in the future to get the upscaler turned off, get a new cable (like virtualLink) from pimax and have the headset running at full res?
Or are there some missing components in the 8K (compared to 8KX) to ever make this possible?

This has not been mentioned by @SweViver On the contrary, he said 5k+ has a small color bending.
The 8k uses 1 bridgechip for 1 input to 2 screens. The 8k-X is using 2 bridgechips[1 per screen]
So the 8k is missing the 2nd bridge chip.

The lines are less aliased on 8K due to the diagonal patter. If you turn your head 45 degrees to the left in Rift/Vive, the lines will be much better, no aliasing. Aliasing is immersion breaker for me.
Yeah, this is one of the variations of the BF-109 with boxy wings, but they improved the design to introduce elliptical wing tips and the shape of the 8K picture simply looks more like it, getting narrower towards the end and having a straight line of the forward part of the wings rather than appearing to have the tips tilted forward. Sorry…
Anyhow, generally the picture comparison reminds me very much of playing around with the sharpen tools in Photoshop & Co… When you sharpen a picture you get the nice effect but the uniformity of plain areas will start to suffer, showing annoying patterns. But from a distance it still may look better, but it is a delicate balance.

Well the displays probably connect to a board via ZIF sockets, and then the board would have either DP or whatever connectors (maybe proprietary like the current 8K) so you need to make a few assumptions here in that:
The 8KX board is (or will be) the same size/ orientation in the case
Any standoffs that hold the old board in place are the same size/orientation/drill pattern as the new board
Plus I am not sure how, but all the IR sensors need to be reconnected.
And even if the 8K setup is comprised of a couple of sub boards- like one for the USB power, a mainboard and the board that drives scaler/DP output, You still have these challenges. Pimax would really need to futureproof the shit out of this thing to begin to offer a setup where the old 8K chassis is essentially “upgrade ready” for a 8K X swap. All it takes is a change in vendor or spec and boom, one of those sub boards is no longer a fit.

The scaler chip cannot be bypassed. The 5K and 5K+ omit the chip. The 8KX will omit the chip too, but needs twice as much circuitry, since 2 video cables are required, because the bandwidth of a single cable (even VirtualLink) is not high enough for 2 panels of 3840x2160 at 90 Hz.
Basically, you want what I want: A do-it-yourself 8K to 8KX upgrade kit. Remove 1 circuit board and install 2 new ones and a second cable guide. Make it available in 3 years, when I have my RTX 2180 Ti card.

I am number 63. (20 characters)
the famous “Monty Hall problem”
suggests that if the host proposes to change your initial choice, it’s worth changing it…
but I’m not the player… I’m the goat
so no one makes me change my initial choice, because with that I’ll never be disappointed.

We know that the 8K is limited to a 1440p signal. But is this per eye?
