ASUS Rog Strix Z390-E.
You wouldn’t have any VRM issues with that motherboard.
If @zoyer can share their motherboard we would have a better idea if the issue is caused by motherboards which don’t meet bandwidth requirements.
Sorry forgot to link. It’s been going on for a while. People have solved it with Steam USB dongles but that shouldn’t be necessary?
@Alex.liu was in contact with steam but not sure what happened after that.
that’s my setup, not sure if everyone missed/forgot about that topic we made.
The extra dongle fix isn’t necessary for some people.
Z370 and z390 both have 24 PCI lanes so it shouldn’t be a lane problem.
Having a Google it appears that the difference between z390 and z370 is lack of USB 3.1 support on z370. Could that be the cause of a bandwidth limitation on z370 motherboards which cause the tracking jitter issue?
“The two biggest differences between Z370 and Z390 are built-in USB 3.1 Gen 2 (10Gbps) and WiFi 802.11ac support. … Given the similarity in features and support for the same CPUs - Intel’s 8th and 9th generation of the mainstream Core processors - the Z390 chipset is mostly just an updated version of Z370 .”
USB 3.0 only has a transfer speed of 5gbps, which is half the theoretical limit of bandwidth compared to USB 3.1
I counter it with this post
don’t play an uno reverse card pls :,D
maybe @Alex.liu could step in and solve this issue for good
Honestly I’m all out of ideas. I was going to suggest that it could even be an AIB specific compatibility issue which affects certain motherboards but seeing as Gigabyte motherboards are affected as well and they’re some of the highest quality motherboards in production I doubt that highly.
One time I RMA’d a Gigabyte motherboard and it was returned to me with a post it note with an arrow pointing to a spot where my cat peed on the motherboard. The fact they had the time to meticulously analyse the board told me they clearly don’t get many RMA requests and their products don’t fail often if they have the time to do that
well i’m just a bit moody because I thought by now it would have been fixed or there would be any statements from alex or the pimax team. If it’s because the old pimax headsets have a worse reciever or something then I suppose this issue will never be solved publicly
Just reading this post and seeing that there’s no problems when one controller is plugged into the headset. This could mean that there’s a wireless data parsing issue, there’s two steamVR tracking dongles in Index and Vive headsets and I’d assume that Pimax also has two internally inside the headset. I don’t know though if Pimax headsets have two internal dongles or just one
There might be other people in your house using wireless.
Have you tried to isolate yourself from all wireless signals and turn all the wifi generating devices off to rule out wireless interference being the cause of the tracking issues?
Yeah one of the 2? 3? times i sent back my index controllers they asked me to shutdown my wifi, fridge and more. So that has been taken care of. Also 1 time hanged sheets around my play area so there would be 0 reflections.
Too bad I can’t post the important parts of my conversations with the steam support since the logs get removed after 60 days
It could be that the person who has a z390 motherboard has wireless interference problems but your tracking issues are caused by the bandwidth limitation of USB 3.0 vs USB 3.1.
You should still be able to solve the issue by purchasing a seperate steamVR tracking dongle and sending half the tracking data into a seperate USB port.
The fact the z390 guys controllers work when one controller is connected to the headset with a USB-C cable indicates he could be experiencing wireless interference.
If plugging one controller via USB-C into the headset doesn’t resolve the tracking issue for you like it did for him, then I think I’m right and your bottleneck is the USB 3.0 5gbps transfer speed limitation of z370 boards.
I plugged to usb c as well and it was perfect. had vive controllers earlier they worked really well but guess they aren’t as needy as the index controllers
Ok so if it’s not caused by
USB 3.0 bandwidth limitation
If it’s not wireless interference if you’ve tried the steps to isolate that problem
It can’t be an issue due to insufficient PCI lanes as z390 and z370 both have 24 PCI lanes.
It’s not an AMD related CPU problem as both you and the guy you mentioned have Intel CPUs
Have you tried using other USB ports on your motherboard?
Have you unplugged all other unnecessary and unused USB devices before testing which could be eating up bandwidth?
Failing that, I think you should just buy a steamVR dongle as that’s a proven fix.
Yeah vive controllers are not a good comparison and it’s a false equivalency as they don’t send nearly as much tracking data or haptic data, remember the Index controllers have finger tracking and capacitive touch sensor data which has to be transmitted, the Vive controllers don’t transmit that information.
yep done all that.
Just feels like if I buy a steamvr dongle it’s like i’m accepting that they messed up (if it’s a pimax problem). I wouldn’t have bought the index controllers if it said that some or early headsets would have tracking problems with the controllers. That’s pretty much what they’re hoping for (I’ve had my share of dealing with the support, gotten to know them well ).
Look on the bright side if you bought any WMR headset and you want to use index controllers you need to buy the steamvr dongles separately, so it’s really no different to using the index controllers on the G2. the additional SteamVR dongles are a necessary evil at the moment for any headset besides index if you want to use the knuckles.
They do as well just check Steamvr panel on desktop it shows 2 watchman dongles. From my understanding with SteamVR each controller/tracker has it’s own watchman. Why tracking pucks if not mistaken come with a dongle to pair with.
Debugging an issue like this can be difficult as there are many avenues to explore.
For example if individual A whom has this issue took his pc and headset to individual B’s house whom doesn’t have the issue. What would be the result?
That being said though with some folks having multiple steamvr headsets and only 1 having the issue suggests a problem with that specific hmd.
