Connection Issues, LAG, Stuttering.


Recommended Posts

Im using an ASUS AX11000, everything in my house has 1200 mbit/s connection issues are not known.

I have a playspace, right next to my router, an ASUS AX11000, a totally overkill gaming router, with near zero latency, lets say 10 ms.

Which is REALLY strange, I can run the glasses for some time, lets say 2 or 3 minutes with 200 mbit/s, I get a crystal clear picture

( as youd expect to ), aside from some tracking issues and lag, then the connection drastically reduces down, picture quality

dies down to mechwarrior 2 style 640x480 VGA, and stays there, the lagging gets worse and so on, its just no fun.

The machine running Steam VR is a STRIX RTX 3080, with plenty of power.

IF I tune down the mbit/s to 100, everything is fine 95 % of time, but with that resolution I could just use my old HTC vive goggles,

which had far superior tracking.

What is going on ?

I have a really good, really fast wifi, with no other strong signals nearby.

I dont connect my computer via LAN to the router, its just not necessary, I get over 1200 mbit/s out of there, and the router is in direct line of

sight 4 metres away.

Is there ANYTHING I can do ?

So far I tried :

- reducing the connection mbit/s ( kinda works, but is not acceptable )

- enhancing the wireless connection with some exclusive channels for the goggles ( which should be necessary actually)

- closer Playspace ( 6 or 3 metres make absolutely no difference)

- updating the goggles ( no more updates available )

- trying to work with vive streaming hub instead of vive business streaming, which didnt work at all.

- updating the router, which didnt change anything

- complaining about the glasses at my neighbours, most of the time, this is a viable solution, but didnt work in thise case.

Stay away with cable ideas.... .

The product is a WIRELESS pcvr advertised for that, and for pretty much everything else you COULD do with vr and mixed reality glasses,

I can just use my vive pro glasses with new controllers and a cable connection if I want that solution aside from mixed reality.

So, what do I do now Vive ?

You got any ideas ?

While I think there is still a fair part that Vive can improve their streaming solution, by tweaking my setup, I was able to improve my experience from basically unusable to near to if not perfect.

The first thing you need to know is that speed does not equal connection quality. My network speed also was perfectly fine the whole time, but the difficult part here is not pure sped, it's more routing, response time/ping and stability/sync.

For example, you're talking about "near zero latency", but then about ~10ms. In terms of network delay in a LAN, everything over 1ms is not near zero. 
You saying "I dont connect my computer via LAN [Ethernet] to the router" basically means that you double the latency, you could have when using Ethernet instead of Wi-Fi. 

"The connection drastically reduces down, picture quality" sound like you have enabled 'dynamic bitrate' in the settings of vive streaming hub. My guess as a software developer would be, that one lag spike results in it being scaled down and the upscaling is probably not aggressive enough to regulate it back up. Try turning it off. This will not help against the initial lag, but could solve the bad picture quality afterward.

One of my problems actually was too many devices connected to the same router, and I'm talking about 0 additional Wi-Fi connections, just a lot of traffic over Ethernet. This never had any impact on my speed, but seems to make problems with routing the VR stream stable enough.

I pretty much dont know, how I could improve the wireless setup further.

I couldnt even read out the MAC-adress, only after resetting the goggles, I could get to it, now I cant update the goggles and the connection is even worse than before.

10 ms is pretty much nothing up to 50ms a "normal" human cant notice that VGA over old tech has that latency and its for flying speed-drones, which I also do.

The problem espescially the lag-spikes, and those are brutal,  and yes I have dynamic graphic quality activated and its just plain unusable without, and the graphics are pretty much very bad.

Without dynamic graphics, the resolution is high, but the glasses cant render fast enough and I get black bars while turning my head and its like moving through honey, no way to win a

stand out game like that.

I dont have any devices other than the cable-modem connected directly to the router.

That Router is like the Ferrari of gaming routers for normal consumers, I dont use industrial tech.

If you sit stationary in front of the computer, it works more or less also with a higher resolution, but not max.

It seems to be the wireless connection of the goggle, and if that doesnt work..., where is the sense in wired wireless mixed reality goggles, pretty disappointing.

Few tips,

I know you may not like this, but I'd like you to first try with USB connection streaming to make sure the PC is ready for debugging wireless setup. 
It's always hard for us to provide direct suggestion on any of the network settings. 

I also have an AXE11000 handy, but I have my PC tethered to the router always to provide steady connection. 

Also check with the network monitoring software or other PC monitoring application, turn them off may help. 

VR is very sensitive of package lost or frame lost, that's why dynamic bitrate is designed to keep the network performance rather than keeping the image quality stable.
It's more like an option to choose performance over visual quality. So, I'll also suggest lowering the bitrate first with dynamic bitrate turned off first. 

I can only suggest this much based on the limited information above for now. but I'd be happy to help you through fine tuning the settings that’s suitable for your environment. 

No guarantee though, Cheers.

I had problem with Wi-Fi streaming stuttering (unplayable at high bitrate and quality) for the longest time and customer service had no solutions for it.
Recently, I've up-graded to firmware 1.0.999.296 which caused the infinite loading screen issue with PCVR library.
To fix that issue, I was forced to use the Vive streaming Hub Beta release 1.1.5 with on my headset (as recommended on the forum), which actually fixed my wifi streaming issue as a side-effect.
I can now play my games over Wi-Fi at high bitrate (most stable at 190 mbit/s) and the highest image quality with just occasional hiccups (still not perfect)
It's worth a try.
