First off - thanks for looking in to this. But, you start off your calculations with the wrong numbers. Pimax Crystal OG rendering resolution at 100% (“High” or 1.0 in Pimax Play settings) is 4312x5104 - per eye! 75% (“Balanced” or0.75) is 3,234x3,828 - per eye. You are correct in that the physical resolution of the panels are 2880x2880 per eye. But the rendering resolution is much higher - like I wrote above. The reason is to adjust for barrel distortion.

Ok, that article is just over one year old as far as I can see. Anyway, how is your performance in 2D in DCS? A guy on a Norwegian forum said he got terrible performance with Pimax Crystal after the update, but then later he discovered he also had gotten terrible performance in 2D too. I have not updated my Pimax Play yet. Only DCS. I have also heard that the external PimaxXR app OpenXR gives performance boost compared to Pimax Play Open XR. But, to make it easier I just use the Pimax Play version.

Not experienced this. But if Pimax Play OpenXR has fixed it, then why worry? Surely you don’t want to use SteamVR OpenXR runtime? And I don’t think the PimaxXR “stand alone app” - outside of Pimax Play - has been supported for a while.

72hz

50ppd has wider field of view.

With today’s update supporting the newest DLSS (4) do we need to mess around in nvidia profile inspector anymore? I do not have nvidia app installed. Also I am not on the newest nvidia driver with my RTX 4090 card.

Calvin’s reply was for the Crystal Super running in high resolution and in TAA. That means rendering in crazy high resolution for each eye. Using DLSS 4 or lowering the resolution just a bit should get you over 72 fps. And then you can run the headset at 72 fps and get it smooth. Even with lowering the rendering resolution on the Crystal super a bit you would still enjoy the fantastic pixel density of the Crystal Super and the great field of view. I can’t stand jittery and stutters in VR either.

Avoid using SteamVR for OpenXR. You fix that by choosing the right option in the Pimax Play App. You will figure that one out by checking the option inside Pimax Play.

Thanks. I think I saw that some got wrong IPD on a recent VR YouTube event and had to manually adjust it. But I think it’s strange that a major selling point like Eye Tracking is *not* on the spec list on a web shop that is selling the headset. That is why I wonder if they are selling a different version too.

Thanks Are you working at Pimax? The web site I plan to order from actually announce it with manually adjustable IPD. I found that strange. I really need to make sure about the eye tracking because running 6240x6280 without eye tracking/quad views… I know about the 57 ppd later. I rather have the wider FOV anyway. So 50 will do just fine.

Thanks. I have a question before eventually ordering - are there different models of the 50ppd Qled Crystal Super? I can not order directly from your Chinese web shop, but can order from a Norwegian retailer. On their website there is no mention of the Crystal Super headset having eye tracking. Actuality on their site it says “manually adjustable IPD”. Do all Crystal Super have eye tracking?

Not sure what to think after watching these reviews. Mura seems really bad after watching MRTV review. It´s even in a kind of a horizontal pattern, according to Sebastian at MRTV. Other reviews mention visible mura as well. For this amount of money I find that disappointing. Hard to see Mura I could tolerate, but it seems to be more than that. Chromatic aberration- my Pimax Crystal has a fair deal of it. But my Pimax Crystal Light not so much. Yeah, I have both I forget it when playing. But if it is more than my Crystal OG, then I am not so sure.

Thanks But like I said in my last post I have the same problem when no other connections are in the USB ports.

Thanks for your input! I have read it now, it does not help me. I have the same problem when no other connections are in the USB ports. And funnily, My OG Crystal has no problems, only my Crystal Light.

Thanks for your input Calvin. It does not help to move the headset around to help with the Not Tracked/Sensors can´t track headset issue. It seems kinda related to the USB 3.0 issue because when I click the "Learn More" which is just beside the "Sensors can´t track headset" warning it, the "Please re-plug the USB 3.0 and make sure the USB is plugged into the USB3.0 port of the computer" comes back up... See picture for what I am clicking which gives the USB3.0 re-plug warning. I got the Crystal Light to work 3 times as it should, no idea what I did. Used the same USB port. One time I re-installed graphic drivers. Next time it worked. (I did not have any problems with that driver and it was clean installed just 3 days ago, but I tried it in desperation). But after re-booting my PC the same issue came back. The other time it worked, i re-installed latest Pimax Play. So I was happy, I tried the headset in DCS. Good as ever. So I exited DCS, and since I had no problem at the time I started the Firmware update to 1.0.14 since Pimax Play asked me to do it. The text said the firmware was fixing some issues, so I hoped these would fix mine. Anyway, the firmware got to 16% and the it said it lost the contact with the headset, please re-plug, try again.. so I did - go to 16% again and same thing happened. So then I aborted the firmware update. I do not think the headset is bricked by this, because I a third time got to make it work again. No idea what I did right that time either. After a reboot the connection issue was there and not tracking. This is very strange. So I am still on latest Pimax Play and firmware 1.0.11 for the Crystal Light. I can at all times hear sound from the Crystal Light speakers by the way. And the panels is not totally dark, just very dark grey. But no star background like it should have. My other Pimax Crystal (yup I got two, one orginal and one Light . ) - the original with eye tracking works as it should. Connects just fine. Tracking and even eyetracking on that one works fine it. I use the same USB 3 port for that one. So.. Not sure what is going with my Crystal Light.
