8KX jitters badly while using lighthouse tracking

Just received the 8KX yesterday and unfortunately the view within the HMD jitters like mad when using lighthouse tracking. If I flip it to internal tracking the view is stable. I’ve tried multiple reboots, HMD power cycle’s, etc… I have an Index that works fine in the same tracking environment - 3 lighthouses. Anyone else see something similar? I’m assuming I may need a replacement @PimaxQuorra @PimaxUSA ?


I would say mine wobbles and is unusable on LH tracking, I’ve logged a ticket and awaiting debugging via teamviewer session.

Does it look kinda like this ?

This is through the lense shot of my 8Kx of an index controller, the whole world wobbles on all 3 axis.

Same lighthouse and PC setup works flawless with my 5K+

I see your controller shaking badly but the menu behind it looks relatively stable. Is it just your controllers shaking? On mine the menu and any object in view all shakes / jitters.


If it’s your whole world then same symptoms as mine. I need to file a ticket. Ugh…

No believe me, it’s everything that wobbels, the whole VR view / world, it’s just because the controller is in focus that one notices it the most.
Will update you once I have had support debug it.

Any update to this issue? I seem to have the same problem

Do you have mirrors, tv screens, windows in the room that can mess up the tracking? I usaly put a blanket over my tv when playing.


So that’s not the issue :wink:

well that’s… novel.

A solution you can test that dont cost you anything but if you only want to complane then do so.

Yeah I have the same problem with mine it’ll do it probably for the first 30 seconds to a minute then it’ll start calming down and stabilizing except last night it was doing it off and on throughout the whole game I was playing

Sorry but I think that you misunderstood my intention with the quote.
If the OP has an issue with his lighthouse tracking with 3 lighthouses, that are running just fine with his Valve Index HMD. Then I do not see why his issue with the 8Kx would be due to reflections on surfaces, as this issue would be (reflected) pun intended on his Valve Index HMD.

I have the simmilar issues with my new 8Kx as the OP, and have a ticket logged on that.
I have a setup with 2 V2.0 Lighthouses that work perfectly with my 5K+ but when using the 8Kx with them, the whole world wobbles on all 3 axis.

So sorry if I offended you with my quotation, that was not my intention.

Yes the tracking is not as good for Pimax but what I ment is you can help it out.

Tracking is perfect on my 5K+
sorry for hijacking @FlagGhost

sberns had his issue solved by support, apparently another support employee than the one that looked at mine for less than a minute

I did but i had different issues - a bricked 8KX and my base station was not being detected. I now also have jitter and if I can’t solve it I will be opening another ticket.

I filed a ticket yesterday. Just to be clear this isn’t a minor jitter that you can play through. The HMD is unusable. Will update here if they ever get back with me.

I had the same issue with the world jumping around and found I had to move the lighthouses much further away from the headset than they had been previously when using the Index. Now about 10ft. Solved it for me.

Just tried with one LH 2.0 only and putting it approx 13. ft away from the HMD.
Same problem, the whole VR World still wobbles like crazy
