@MrAhlefeld
Some people are supposedly quite sensitive to the polarization of light, perceiving something like a yellow/purple shape. Are you? I am not.
If that is not what you are seeing, then this is probably due to angle-dependent defects in the color quality of the 5k+ LCD, or due to subtle deficiencies in the software chromatic abberation.
In the latter case, I would expect the 8kX to usually be vastly superior.
The 5k+ panels have color quality problems typical of older LCDs in general. When I used the 5k+ for debugging a few weeks ago, the difference was immediately staggering. The improved dynamic range and saturation of such panels is usually associated with the drastically better control needed to minimize viewing angle problems as well.
Chromatic abberation correction should be more accurate with the 8kX, because the offset between RGB subpixels is smaller. I can confirm the abberation correction remains sub-pixel accurate on the 8kX.
Frankly, the 5k+ was what I consider the first entry-level VR headset. Adequate resolution, adequate FOV, but such severe artifacts - especially what I now know is called āpixel walkā - that I just donāt notice the more subtle defects.
However, there is one exception the 8kX does not solve.
I definitely have seen yellow/purple banding around OVRDrop panels. This is apparently because the chromatic abberation is not applied to the edges of overlay applicatons. As this is a SteamVR problem (by the way, SteamVR is bad), there is only one solution.
Yeah I would agree that this is chromatic aberration issue, and glad to hear that it is not an issue on the 8K X pre-prod
Thanks for testing and giving a thorough answer.
I will need to do a follow-up test with my 5K+ tomorrow, just a little thing I might ask you to try in a PM
Yes, this is my conclusion as well. It seems as if Pimax have no money nor stock to serve the backer & older pre-orders because, honestly, if they had them in stock, why would they not have shipped them back in January ? Before Covid-19 appeared on the screen ? Matthew Xu had confirmed in December 2019 that they would have sufficient numbers in stock in January. But that of course was already not the first time we had been told the shipment would start within 2-3 weeksā¦ Kevin already announced that in Spring 2019.
We will be sitting here in Spring 2021 too debating about Pimax latest promise to ship themā¦
But no, wait, I was told that mine will ship this Friday or Saturday ! This time it will be different, for sureā¦
That was during the kickstarter. After Valve changed Lighthouse supply agreements both HTC and Pimax could not for a time do so until more recently just last year. Valve removed the bundle condition.
IIRC Pimax initial promise after receiving the base stations from valve was to ship them to backers in December 2019ā¦
There would have been no problem at all to do that as this was way before EU was locked down, but as usual Pimax didnāt hold their promise, they have dragged their feet again pretending they had to double check every single base station to justify more delays (as if 1.5 years delay wasnāt enoughā¦), while they were probably hoping upgrade plans would disengage them from most of their obligation to deliver base stations from the kickstarterā¦
Now the EU is locked down, all of a sudden Pimax shows a will to finally ship those KS base stations, asking people to confirm their address. This makes me feel you seem to take this EU lockdown as a nice opportunity to try to force backers to accept a shipment from HongKong so you donāt have to organize the intermediate step of importing the base stations to the EU warehouse and reship to backers from thereā¦
We are only a few dozens of backers waiting for their KS base stations from an EU warehouse, but you seem to prefer to keep those unsatisfied backers complaining on the forums instead of taking the appropriate measures to deliver those base stations once for all, so we can get out of this nightmare from 2018ā¦
Again@PimaxQuorraare you still going to ship separate base stations to your EU warehouse ? This was your promise a few weeks ago but then why sales support didnāt seem to be aware about this at all ? I hope this is not just another strategy to continue playing the watch with us, with no intention to ever ship any backers base stations from your EU warehouseā¦ How many weeks do you need to organize a resupply of Marseille warehouse ? Why the shipment to Marseille hasnāt even left China yet ? You have announced it weeks agoā¦
That thing about only being able to sell lighhouses in bundles is still a possible explanation.
Another posibility that seems obvious to me is that they only asked for 75 bucks per lighthouse back in during the kickstarter, half of what Valve is currenly asking for.
Due to this they have only been shipping out base stations to people that have bought the (press) F (in chat) package.
The F package effectively brings the amount paid for controllers+lighthouses during the kickstarter+the āupgradeā(+shipping) within a few dollars of buying lighthouses+controllers straight from valve in your region with the added bonus of super sketchy delivery times and added headaches if there is ever a need for any sort of support.
(and if you get hit with import duties it will have been more expensive)
Then youāll miss out on an 8K X that the rest of us will enjoy
Pimax is not going to ship out base stations that are now more expensive than they were initially. Theyād lose money doing that. Make a new thread about base stations. Letās move on to other more important topics.
Will the standard MAS ship together with the 8K X headsets?
Will the eye tracking module support dynamic foveated rendering on the 8KX, allowing for improved performance and potentially a distortion free experience?
Uh to be clear, I did intend to indicate it might not be solely a chromatic abberation issue. Opposite viewing angles would also affect the 5k+ panels, causing left/right sides to be tinted differently.
To break it down, there are three issues I suspect are indeed all affecting the 5k+ here.
Opposite viewing angle discoloration. Probably ~10x better from 5k+ to 8kX.
Chromatic aberration RGB subpixel offset distance. Probably 4x better from 5k+ to 8kX.
Overlay edges discarded in chromatic aberration correction. SteamVR architectural issue, no improvement.
Very curious what you might want me to test! Please remember to continue pinging me with that ā@ā .
Do Pimax plan to keep running production of 8KX while first 100 of 8KX is being sent to first 100 users, or plan to wait for feedback in case there any changes to be made?
Hmmm last I remember from Kevin and Sweviver was yes, but I could be wrong. With the exception of the 100 test units, they didnāt want anyone to receive anything but the full package. One of the reasons that the MAS status is just as important as the 8KX, because one wonāt ship without the other.
Iām good with this, because for me the MAS is the most important kit they have to deliver. I wish I could have had one for the 5k+ all this time, instead of using it in a compromised way.
I just got this email from Doris in support. Looks like if I want the base stations I Backed I will have to pay an additional 40CAD to have them delivered within 10 days. In addition since shipped direct from China there may be a hefty duty charge and wait at the border.
Dear Pimax backer,
Weāre very excited that the shippment of the base station you are looking foward to finally start though we had faced many challenges including very limited resources and very tight express. Anyway, with your support, we are happy to start the delivery for you.
Before the delivery, we have a few points to let you know:
Freight:
a. Pimax offer the free freight for all the customers whose order no more than 2 basestations as the current freight is extremely expensive and Pimax can take the cost for our users. But during the COVID-19, it takes about 4 weeks to reach you.
b. If you ordered 4 basestations, you have to pay extra $15 for the shipping for the other 2 basestations.
c. If you prefer faster freight, Pimax offer VIP Express which takes 7~10 days and charges extra $15(the current cost is around $30). To make up the price difference,please check this link: https://store.pimaxvr.com/shop/product/price-difference-price-difference-293?category=7
Customs Tax:
As Pimax ship the basestations from Shenzhen, the customs tax may happen, so please support the customs clearance if requests and tell our helpdesk, otherwise the item would return to Pimax again.
Weāll start shipping immediately once we get your confirmation.
