The only issue though is the Lighthouse issue should be very high priority as it can affect multiple models of pimax hmds.

I’m not disagreeing at all… 
I’m merely saying that it would make sense to me if 90Hz got more attention “upstairs”.
It’s bling (and something to campaign) where jitter free tracking is just expected at this point.
Who knows what the world looks like from their view?

i am all team red.
played project cars 2 last night,4 hours, at 90hz 90fps,150fov.
no blackouts
i have never had a blackout, so far.

Has anyone gotten a solid response on the blackout issue from pimax support? Supposedly they saw that my logs had an abnormality and showed the line that said “TE NOK!!!” and they said that shows them there’s an issue but the support rep is saying they’re trying to recreate the blackout to find out the root cause. This could take months if that’s the case.
I dont know what else to do other than sell the headset which is what i will end up doing soon.
@PimaxQuorra @PimaxUSA - is there any way we can get a response as to what is going on? They’re not saying anything.

Not a word back from anyone @PimaxQuorra @PimaxUSA - Pimax seems to have no clue what’s happened with the blackouts. Does anyone know anything about it?

Does everyone have a direct drive wheel that is having blackouts? I wonder if this is an EMI issue effecting the cable signal quality?
I have a DD2 - but ive been using the same cable and multiple other headsets. None other than the 8k x causes this. I thought maybe my motion rig’s EMI causes it, but that’s not the case either.
But the 8kx is running 4k x 2 at 90Hz! So the bandwidth is being pushed more than other headsets.

I was using 75hz also - same thing. Downsampling - same thing.
I bet the Vive Pro 2 wont have this issue
And using the 5k Super pushing the supersampling just as high on the resolution and no blackouts either.

That’s a totally different thing.
I think it’s a bandwidth or panel (or controller for it) overdrive issue.
Supersampling doesn’t affect either.
Resolution + refresh rate sent doesn’t change when changing resolution in the rendering pipeline.
EDIT: It might also be a power issue but if that’s the case, I don’t understand why it doesn’t work when using a USB charger attached to the USB 2 (power only) cable.
EDIT2: Plus Display Stream Compression (DSC) is used on the 8KX to achieve 90Hz so it might (hopefully) also “just” be a driver issue that can be ironed out by Nvidia and Pimax in a joint effort.

Thats what i think - it could be something driver/firmware-level issue
But its definitely a problem with the 8K X and Nvidia gpu’s in general it seems. 3 people i know have now sold off their 8kx hmd’s because of this. Im still holding onto one but i dont know if i will.
I do think it could be bandwith issues where it overloads bandwith and caused the blackout for a few seconds but i wrote support back again to see if there was any updates and asked them to try an RMA (this would be a 4th 8kx i would be trying) and they said they have a meeting on monday to discuss my issue and would get back to me then

Does anything else use DSC?

HTC states that Vive Pro 2 is the first to utilize it (guess they “forgot” Pimax 8KX)… 
Not sure if other Pimax headsets besides the 8KX have used it though?
Maybe @PimaxUSA knows for sure.

Oculus Quest uses it and ARM Processors i believe had it before HTC - i remember reading this and posting about it in discord too.

If it was a driver issue then wouldn’t this also be an issue for those HMDs?

I dont mean it in that sense. I mean there’s something conflicting between Pitool, the firmware, and how it works with Nvidia’s firmware.
We do know for a fact that there’s an Nvidia issue that’s been present for a few months now with SteamVR causing lagging and such, and with the most recent nvidia firmware updates they found a temporary fix but you can’t use gpu monitoring software.
Coincidentally after they implementing this fix ( nvidia firmware 461.33 and after) - the 8k x headsets no longer work at 90hz either.
It does seem that something is there that may be causing it and may even be related to the way the pimax 8kx works with the nvidia drivers - but im grasping at straws because i have no knowledge of how it works. It’s just very coincidental stuff i thought might be correllated to it.

Yes Arm Processors had DSC long before pc gpus. Pimax had originally thought they might have been able to use DSC to unlock 4k Res on the p4k; however a few things including Nvidia/Amd gpus didn’t support DSC. This at that time was Arm gpus.

Hello,
The tech team is trying to recreate the blackout issue, this would help to resolve.
But they failed to do, and figuring another solution.
We suggest them to contact with you again, to get all the logs and setup, assuming this could be helpful.
