I think I’m going to. It seems like the better option for the future. With super sampling, the blurriness produced by the upscaler might be reduced/eliminated. That’s gonna take some serious horsepower to run at a good framerate, but that’s just now. In the future though, they eye tracking module will be delivered to backers. Foveated rendering will come around eventually. Even if it takes until 2020. I think once foveated rendering and the eye tracking comes about, it’ll allow us to crank the supersampling up and the 8k might end up looking better than the 5k+.

I’ll also stay with the 8K for the same reasons as you.
The 5K+ may look crisper now, but with good supersampling, I think that the 8K can achieve the same crisp but with more resolution (similar as the 4K).

I haven’t found a clear comparison of sharpness with the 8K supersampled. If it gets just as sharp I’ll stick to the 8K as well. I can live with a bit a smoothed out picture until the new horsepower arrives.

You might be right, it should be possible to reproduce what the best case scenario is for the 8K just by cranking up the render and SS to insane levels and screen capturing the result. Even if it only runs at 1 frames per second, the frames that are there should tell the story. I would like the testers to try this so we can see how the 5K+ and 8K max out.

I think the big reward for anyone sticking with 8k is they are probably going to get their unit really quickly.

I will firstly await the benchmarks of the 2080Ti, and then Sweviver’s revisits of the 5K+ vs. 8K issue as soon as he has planted the 2080Ti into his system. That may make a difference.
But from all we know it seems that the 5K will simply look better with the 2080Ti level GPU power than the 8K, and the advantages of the 8K may only materialize with a 3080Ti or 4080Ti (I believe it was VoodooDE who said that). In that case it is pointless for me because by that time I surely hope that I have replaced the 8K by a shiny new headset offering foveated rendering, etc… I am not making a one time investment with no funds to buy a new headset in 2 years from now (and if I only had such limited funds it would mean that I cannot afford the expensive 3080Ti/4080Ti either, right).
Besides that, I also will receive a 8K(X) at some stage, so my crazy high-end itch will be scratched by that one.

I’m going to stick with 8k. I’m going to use supersampling anyway and for sure I’m going to play with reprojection enabled, everyone will so far, based on reviews there are no games running with 90 FPS, so I don’t really see a reason to stick with 90hz (90 FPS \ 45 reprojection) if there is 80hz with less SDE available which will need to render at least 40 fps in reprojection mode.
Based on reviews (again) almost all games can do 40 fps even with supersampling and high fov preset. And if not, 2080ti might solve that for sure.

You guys think you can SS with 8k lol
Maybe 5 years time with 4080ti

Reprojection is awaiting brainwarp. We really need to know how the 8k runs with brainwarp along with details on eye tracking and foviated rendering for a fully informed choice.

i think @SweViver s review is very clear on that, much more than the other youtuber reviews. With the Pimax8k there is the chance of getting more detail and same clarity when compared the Pimax5k+.
All it needs is a really decent GPU and optimized settings in PiPlay and SteamVR, benefits of Oculus over SteamVR are not analysed but possible too.
What is open to explore is perfomance improvements of
- higher VRAM bandwidth of next RTX GPUs
- benefits of brainwarp
- further optimizations in game settings and VR runtime settings
- further optimizations of Pimax software developers
- possibilities of multi GPU in future titles
- possibilities of OpenXR with all vendors know how combined
The 8k future doesn’t look that bad really, quite the opposite. But sure it’s a little up in the air.

I’m not talking about brainwarp, I’m talking about basic reprojection already presented on the market. I can’t believe that none of them is used by pimax. Look at those Benchmark results, 40fps / 50 FPS / 60 FPS…and when it comes to “decent” it’s only around 70. Its not possible to play with 90 Hz refresh rate displays with 70 FPS without reprojection, it should be unplayable in this state, that’s the reason why the reprojection was made (to keep 90 FPS when it drops below).
If I am right and they use interleaved reprojection (first and basic type) - the game will only need to render 50% of the refresh rate, considering 8k it will be only 40 FPS. 1080ti should be able to run with stable 40 FPS and there will be space for supersampling.

I think i will stay with the 8K. not 100% sure yet, curious when we have to decide btw. Hope after @SweViver’s 2080Ti tests

@Sweviver, can you please clarify whether the 8K/5K+ use
- Reprojection tools of SteamVR when operating SteamVR games
- ASW/ATW when operating Oculus games (without Revive, but directly) ?
- and if Oculus games do not use ATW/ASW when operated directly, would that be different if using Revive ?
I am just wondering which reprojection tech is being used by the Pimax when they drop below 80/90 FPS.

Would it be possible to post a very high SS images for the 8K so we can see if the clarity is comparable with the 5K . I know it might run a 1 FPS but it should be enough to capture an image.

@shinytomb I have the same ideas in regards to future-proofing as you do.
At the moment I’m sticking with my 8k.
I also like the 8k’s colour tone better.
I’ll have to buy a 2080 ti and a new PSU though

Talking about super sampling the 8K to match the 5K+ with the 2080Ti extra grunt and other features like foveated rendering may make the 8K match the original 5K+ but what about if you also super sample the 5K+ with that extra grunt?
I do not think Super sampling will help because of that and also the upscaler will always soften the image regardless.
If it was me I would keep the 5K+ and in a year or two sell the 5K+ and get the 8K-X when foveated rendering becomes a thing or engines start to enable features like MVR automatically.
Just my opinion of course.

I was thinking about the same thing. If I have it correct, the 5K+ and the 8Kx are both using the native signal.
8Kx is using two bridgechips if I remembered correctly from this forum, but still native.
The 8K is the odd one out there. Not carrying the native signal but rather the supersampled version.
I think native is the way to go. I’d like to have the experience of both headsets too somewhere, but I think I can trust all the testers and the backers attending the Berlin event.

by the great atheismo is hard to choose.
i look at one pic and i’m 100% sure its 8k then i look at another and the i prefer the 5k+
one thing that @SweViver did pickup that the other reviewers did not is the different pixel patterns between the 5k+ and 8k.
the 8k seems to have a diagonal pattern whilst the 5k+ looks much more like the pixels are layed out horizontally… i do prefer the horizontal layout of the 5k+ but i think the upscaling / slight blurring of the 8k gives a natural kind of anti-aliasing.
overall tho, any reduced SDE wins for me. i hate SDE, i prefer PSVR image quality with its low res but very low SDE over the vive as SDE is a complete immersion killer.
then there are the weird dots in the 5k mentioned…
so stick with 8k is winning.

I think it was SweViver’s review or maybe VoodooE but one of them already confirmed that the Steam reprojection techniques are not used by the Pimax units at all. It ignores them similar to the way the windows mixed reality headsets ignore them. Brainwarp will be the Pimax reprojection technique whenever it becomes available.

OH TWIST, I’ve decided to save some money, and just go for the 5k+ & 2080 (non-Ti). I won’t have to buy a new PSU for that card.
Which also means I can get Pimax controllers, and save about $500 all up.
I’ve been thinking it’s odd for Pimax to keep the 5k and the 5k+ for retail, 'cuz who would buy the inferior 5k?
Taking that further, with the vocal majority here being in favour of the 5k+, why even bother with having an 8k anymore? Pimax might have an opportunity to streamline their workload and their catalogue, if they can replace the 5k and 8k completely with the 5k+.
They can still give the already manufactured 8ks to their commercial partners as they apparently don’t mind, and to any remaining backers who still want them, so they won’t totally go to waste.
Weird dots on the 5k+ are the only issue for me now.
