Updated 8K review, with an emphasis on Elite Dangerous



I got my 8K a week ago. It took me about an hour to get it running. Most of the problem was getting my (single) base station configured. It was recognized the very first time and then it wasn’t recognized and it took at least 30 min to get it recognized again (following SweViver’s suggested steps in the wiki). I just kept repeating the suggested steps and on about the 5th retry it worked, although I don’t think I did anything different. It just seems very touchy (and yes my base station was ~2.5m from the headset.

I initially used the .95 version of PiTool, since that’s what seems to be the most reliable and I wanted to have a solid base line, before I upgrade. Since the latest version seems to have a “stuttering” problem, I’ll probably wait for others to test the next version before I upgrade, which I did a few days later, to version .111.

Based on my initial experiences, I would not recommend this headset to anyone (at this time) who isn’t technical. I found it frustrating and it took me over an hour, mostly trying to get my base station to be recognized. The first attempt worked, but then PiTool wouldn’t recognize it. I followed SweViver’s recommended procedure in the wiki, but it stilled failed to find it. I wasn’t sure what else to do, so I kept repeating the sequence with some reboots thrown in for good measure and eventually, the BS was recognized, but I’m not sure what (if anything) I did differently that time.

Eventually, I discovered a method to consistently get tracking to work. I hold the headset close (0.5 m) from the base station and slowly move the headset further away. If tracking hasn’t kicked in by the time I reach 4 m, I repeat the procedure.

I didn’t notice any dead or stuck pixels, nor did there seem to be any dust on the lenses, or other headset defects. The SDE is definitely noticeable, especially when looking at text, but it didn’t really bother me. I didn’t notice any distortion either. I did notice a strong chemical smell from the foam face-pad. After a few days the smell has faded.

I noticed a USB issue: When my PC boots, I see an error about a missing keyboard, but by the time Windows has initialized, the keyboard works fine. (I can log in.)

I don’t have any heat problems. I used my 8K for ~3 hours and it was warm, not hot. There was no sweat buildup or fogging. My face did get warm from all the foam (which is insulating), so I needed to turn on a room fan.

I had a power issue. The Pimax power dongle needs an LED to indicate when it has power. Not everyone has a multimeter for testing these sorts of issues.

I’m not fond of the headstrap. It places too much pressure on the lower part of my face, which presses on my sinuses and makes it hard to breathe. I tried the “comfort strap” mentioned in the forum. It felt better, but didn’t help enough. I’ve counterweighted it, by attaching a bundle of metal wrenches at the back. I plan to get the following product, for a permanent solution: https://www.counterbalancevr.com/product-info

I had to frequently clean my glasses; they kept getting smudges on them from the face pad foam. I have to be very careful when I put on the headset or else I have to immediately take it off and clean my glasses again. The prescription lens insert needs to ship ASAP. I’ve started thinking about Lasik, since I’m not fond of contacts.

I played Elite Dangerous for about 3 hours in my very first session, but the real wow moment was when I stood up and walked around the cockpit. It was gorgeous! I did not have any problem with nausea at all, even when I drove around in my SRV over bumpy terrain.

After ~3 hours of play, my system also crashed. I’m not sure if it was the Pimax or Elite Dangerous, but I think there’s a good chance it was ED. I’ve not seen another crash since. I’ve now played quite a few 2-4 hour sessions. I’ve only had limited VR experience, but I found the 8K to be easy to adapt to. During the course of my testing, the framerate dropped into the mid to low 20s, but the game was surprisingly playable even so. I’ve tweaked things so that my framerate is generally 72 Hz. I’ve included my settings at the bottom of this post.

My self-measured IPD is 63 mm, but I’ve found 65 mm works best for me. Yes, there no noticeable distortion. I measured the pad thickness at the top (thickest part) and it was ~14mm. I saw distortion when I pulled the headset out (away from my face) and did see some distortion then, so I chose NOT to use a second face-pad on top (even thought I bought one just-in-case). The lenses wear quite close to my face, but I was able to wear my small-framed “computer glasses”.

I did notice some tearing or wiggle, when I moved my head quickly to the left and right. That’s probably due to the low framerate. (I was in a station in ED.) I couldn’t figure out how to see the framerate, even though I have the VR FPS tool. I was too excited to play, so I didn’t spend much time trying to figure it out. The tearing didn’t bother me, during actual gameplay.

The black level and colors are good, for an LCD screen. It was better than I expected, actually. Videos with a lot of skin tones (ah hum) look great on an 8K. There is noticeable color fringing when displaying thin lines (like orbit lines in Elite Dangerous) which is due to the “rainbow” LCD pixel arrangement and I could see the individual pixels whenever I looked at text, which resulted in minor SDE. The SDE is most noticeable on bright areas; I can ignore it, but it’s always present.

During play, the visible pixels didn’t bother me, but the color fringing did. (Orange lines are red or green in alternating patterns.) I’ll try to get a photo later. I normally play with orbit lines off, so this is not a deal breaker, but if this bothers you, a 5K+ is probably a better choice, even though the larger pixels would be even more visible.

I’ve noticed slight red/green color fringing on the letters. To some extent, it depends on the amount of super-sampling you have selected in PiTools and SteamVR. The orbit lines have the most obvious issue and the moving vertical lines (when you’re in super-cruise) also show the fringing a lot, but they are on the sides (where it’s not as visible). The orbit lines are often right in front of you, so the artifacts are hard to ignore.

[ update ] I’ve greatly reduced the color fringing on the 8K (it’s not a problem on the 5K+, due to full RGB sub-pixels) by tweaking the ED per-app super-sampling in SteamVR. I’ve set the video SS to manual at 20% and the ED app SS to 66%, for a per-eye resolution of 3220x2836. In space, my framerate is maxed out (to 72 fps) and in stations, it’s 40-45 fps (which is fine).

I wear progressive multi-focal lenses in my regular glasses, so I may be more tolerant of distortion effects. Note that I tested with my computer/reading glasses, which have standard (non-progressive) lenses.

I tested for distortions in the ED waiting area, which is a spaceship hanger (large room), next to an SRV (rover) and a ship. I also tested this on a planet surface. Distortions were minimal. It’s possible my face shape is particularly well-suited for the Pimax. I wear progressive multi-focal lenses in my regular glasses, so I may be more tolerant of distortion effects. Note that I tested with my computer/reading glasses, which have standard (non-progressive) lenses.

I had no problems in the binocular vision overlap area, but my left eye has “issues”, so the overlap area will be dominated by my right eye and my ability to see depth is somewhat limited. I need to get new glasses, which will help in this regard. Even so, the environment of my ship’s cockpit felt very real and I got a good feeling of depth. One thing I noticed was that the starry background of space felt “too close”, instead of feeling like it was in the far distance. The stars seemed much further away, when I was on a planed and had a horizon for reference, so this might be some sort of optical illusion.

I do see the SDE constantly in ED, especially when looking at text. I can ignore it, but it is there. ED looks best on an 8K with super sampling set to 2.0. This reduces crawling jaggies and color fringes on the edges of thin lines and text. If you set the resolution too high in PiTool or SteamVR, thin lines (like orbit lines) can have a lot of color fringes, to the point where orange lines are displayed as red/green dashed lines.

I had a problem with the headset applying pressure to my face (not my nose), which was uncomfortable. I found a good solution: A counterweight. Temporarily, I bundled a couple of metal wrenches in tape and attached it to the back of the head strap using the Velcro loop that held the Pimax cable in a loop (for packaging). It works really well to reduce the pressure on the front of the headset and balances the weight. My counterweight is 11.1 oz / 312 g, which is about half the weight of the headset alone.

Unfortunately, my headset cable appears to be defective. I often see red or green sparkles (which is ignorable) and black or white flashes (which is not ignorable), and occasional headset lock-ups with horizontal stripes or black displays. I know it was a headset issue, because the game was still running in the on-screen mirror window. I contacted Support and got a reply within a day; Pimax will be shipping me a new cable. In the meantime, I can still play in VR, but the video artifacts are annoying.

My system has a 6-core i7 8700K running at 4.88 GHz, 16 GB of G.SKILL Ripjaws V Series DDR4 3600 RAM, an overclocked MSI RTX 2080 Gaming X Trio Video Card, an ASUS TUF Z390-Plus Gaming motherboard, and 3 TBs of NVMe and SATA SSDs. The 8K runs pretty well on my system. After much experimenting in Elite Dangerous (I rarely play other games), I’m using the following settings: PiTool: Quality at 2.0, no smart smoothing, no fixed fovea rendering, 72 Hz refresh, Normal FOV. SteamVR recommends 12% super-sampling, but won’t let me manually set it below 20%, so I have it set on automatic. My ED settings are below.

Overall, I’m quite happy with my 8K.

Smart Smoothing?

Very nice Neal!

Tip for you though, the colour orange in vr is never good, as you are using Dr Kalis Ed profiler, search online for ‘optimal hud colour for Vr’. There are some good ones that will move you away from the default orange. And it makes a huge difference, personally I use whites, creams some yellow with red for enemy’s and shields.

I can give you my hud colours tonight when I get home from work, they work really well in VR.



Thanks for the tip!

I’ve tried a lot of the color choices. I don’t like any changes to the radar color-coding (red for enemies, green for friends, etc.). I’ve desaturated the orange, so it’s more the color of a dimmed incandescent bulb. (Notice how much blue I’ve added to the red and green.) It might not be all that different from the cream color you favor.

Here's an in-game shot...


Hmm it is similar, I will give you mine anyway… Im the kind of person that like all options on the table if you know what I mean.

Will do it tonight for you.



here you go Neil…

<MatrixRed>0.35, 0.5, 1.75</MatrixRed>
<MatrixGreen>-0.5, 2, -1.25</MatrixGreen>
<MatrixBlue>1.75, -1, -0.4</MatrixBlue>

i have loaded my colour profile into this site for you http://arkku.com/elite/hud_editor/#theme_0.35_0.5_1.75_-0.5_2_-1.25_1.75_-1_-0.4



Thanks. I tried it, but I prefer my “soft orange” custom HUD colors.


All good Neal



Do you have vive controllers?
Often I have to turn them on first to get the base stations detected.


No, I am only playing seated games. My VR play area is only 2x2.5 m next to my desk (and it’s only that big if I move my computer chair out of the way).


Same here…


@neal_white_iii here my system specs
Ryzen 5 2600X clocked 4.2 ghz
MSI 1080TI OC Armor clocked to 1.9 ghz
DDR 4 3000
ED on my SD drive


That’s fairly similar to my system, as described at the end of this post: Updated 8K review, with an emphasis on Elite Dangerous

I’ve been tweaking SteamVR super-sampling settings. I’ve found that rendering each eye at 3364x2963 yields a good balance between sharpness and color-fringing on the 8K. I’m still investigating that, so I may settle on something a bit higher or lower.

I’m running with PiTools settings at: Quality = 2.0, 72 Hz with both Smart Smoothing and Fixed Fovea Rendering turned OFF. In ED while in space, I’m usually at 72 fps and in stations or on planets I get ~60 fps.

I suggest running these 2 utilities, to verify that you don’t have some sort of PC problem:
. https://www.userbenchmark.com
. thebottlenecker.com

Please refer to my ED settings in my post above. Run ED, preferably with fpsVR active (or use some other method to determine your actual fps).

Once you’ve done that, please post your findings and I’ll try to help you reach optimum settings for your PC.


Rather that clutter up the other thread, reply to star and shadows in this one. thanks.


OK, I’ll try that tonight. I normally scoop with the star directly above my head.

What I think you might be seeing is an issue that all LCD panels have: The blacks and colors are not as good, when viewed at an oblique angle. The only solution is an OLED display (for now, other display technologies are in development).

Personally, I’ve been using LCD monitors for years and that’s not something that I notice anymore. The 8K appears to have better blacks than my 4K flat monitor, which has some minor glow at the edges of the screen. I don’t even notice that, when I’m playing.

Eyestrain discussion / Problems and Solutions

Yes I have found that star above or below is ok, only when star on left or right, really dose your eyes in. like having one lens from dark sunglasses in one eye.


have you tried pp on/of for these apps?


Elite dose not work with out PP. :frowning:


ED i really hope pimax will look into that game, the only one i’m dissapointed with, i liked it much more on my lenovo explorer despite of the colors and blacks,it had better performance much more sharperness. I did find sharp settings, but i can’t’get it buttersmooth it breaks my immersion


The only issues with my 8K which I notice while playing are: Pixel snow, occasional black and white flashes, and SDE. The first 2 will hopefully be fixed with a replacement cable, which is supposedly on the way to me. The SDE is minor, but I see it whenever I look at text in ED (all the time); I’m glad I got an 8K, instead of a headset with even worse SDE.


i think you need an O+ to get rid of it in ED and it has much beter performance.
Despite of ED i’m happy with my 8k also, the screendoor and colors are great in other games
I think the rendering is so completly different in ED it does not seam to match well
