New Pimax 8KX Jitter

Pimax Hardware P2: 8kX

hi
I have the same problem as you with the base v1
because without the base it’s perfect

steam vr and htc1 bases are maybe just forgotten in the updates to sell v2

Strange. I’ve never noticed any jitter on my 8K or my 8KX. I never even thought it could be a problem.

I’m only using a single v1 base station. I have a 2nd base station, but haven’t bothered to install it. I mostly play seated games which only need 1 base station, but I’ve also played Half-Life: Alyx and I didn’t actually need to mount another base station. It works fine as-is.

Yeah looking at the thread and talking to some owners on Reddit it seems like it you have V1 base stations, it’s fine.

I have V2 base stations and it’s terrible. I’m not going to buy V1 base stations just for this headset. Pimax really needs to sort this out.

I’ve never noticed it either and I only own v1 basestations.

Agree. The solution is not to buy outdated products when new ones are available and are supposed to work according to spec and marketing materials.

If possible, they should develop a calibration tool and build it into PiTool/Pimax Experience.

I’m actually shocked that considering how long the 2.0 base stations have been around, Pimax haven’t fixed this already.

I’m absolutely happy to spend the £1,250 I paid for the 8KX but not if it has some ridiculous soft-incompatibly with the current gen base stations. I want the best, not a compromised vr experience.

Is there a proper tutorial on how to calibrate it with V1 base stations or with a Valve Index, etc.?

I have 2.0 and never had such problems.

it has always worked great for me.

I do not understand the problem

Jitter probably because you set the resolution too high on SteamVR. Try to play around with the settings is all I can tell you.

Please run the jitter test in my original post and post your results please

Agreed. Considering what has been said, I’m glad I bought base station v1. I got them way before v2 was available.

i also had a problem with the image but mine is solved by disabeling hardware accelerated gpu scheduling maybe you could check if its enabled and disable it to see if this also works for you
its in settings/system/display

Tutorial I did not find, but there are many documents for the creation and calibration of an HMD or any devices based on tracking with lighthouses in SteamVR Tracking HDK. Which can be obtained free of charge upon registration at: Welcome to Steamworks.
Once downloaded and installed on Steam, you can have the utility to calibrate the optical sensors “vrtrackingcalib”, where you only need to have your “config.json” file from your Pimax and put it in the same path. Run the program as follows: “vrtrackingcalib.exe /bodycal 800 200” and when it appears:
Ready to run capture position number 0.
Press key to begin:
Pressing enter and moving the HMD around the room and rotating it to show the lighthouse all the sensors, the calibration progress will appear until completion, where it creates a new .json “auto_ .json” ready to send to the HMD.
Using “lighthouse_console uploadconfig auto_ .json”
For the calibration you have to use a single lighthouse v1.0, if you have another you have to turn it off.

Here is a video I made with the progress of the calibration:

  • Max Deviation (Rotation) 0.11

best:

  • Max Deviation (Position): 0.67

1.0 or 2.0 base stations?

20

I’m using 2.0 base stations…

Thanks, while your jitter results are better than mine, the average is still 3 to 4 times worse than my Valve Index. This level of jitter just isn’t acceptable for such an expensive headset.

My test results are very similar to this. Would love for that jitter to be reduced. I can deal with it but it’s far from comfortable.

This issue with BS 2.0 jitter really needs fixing and Pimax Technical support need to correct it with an update.
@PimaxQuorra @PimaxUSA

Or I might buy a single BS 1.0 and see if there’s any jitter. Do 1.0 work with the Valve Knuckle Controllers?

25

Yes, I use 1.0 base stations with the Knuckle controllers…no issues with Jitter
