Choppy Preformance with Wirless Adapter

Re: Choppy Performance with Wireless Adapter

Just chiming in to log the exact same problem as everyone else. Fresh install of windows 10, vive, and steam, and I get 100% processor usage at all times when vive wireless is working, even in steam VR home which is simple. VR compositor, VR tours, and System are my main users. PResumably System is the driver interacting with the kernel in windows 10, and it's usually down around 10% or lower. So I don't believe this is an issue of data compression taking too much CPU. This is some other problem. Games all run just fine when wired, of course.

 

Also, this thing does not work on windows 7. a travesty. Why did HTC put out advertisements claiming it works on windows 7? BAsed on my reading of the internet, to my knowledge, no one running windows 7 has made vive wireless work (that's why I tried this on a fresh windows 10 install).

I would recommend adding your detailed PC specs, it can be helpful when their support team reviews this issue.

Re: Choppy Performance with Wireless Adapter

sure, it could be worth it:

1070ti

core i5 2500 @ 4.2GHz

8GB RAM

Asus P8P67: 2x PCIe x16  (one is x4 speed); 1x PCIe x1

All my PCIe's are gen 2. I have my WiGig adapter plugged into the x4 speed slot, which is the only one I have open, because the graphics card covers the other one.

 

I don't have PCIE gen 3, but notably the specs seem to just ask for gen 1, a PCIe x1 slot.

 

Anyway, probably am just going to return this and buy it again in a year or so when it is actually working. Fixing the driver so this works in win 7, or so that it doesn't rail the CPU in VR should be a trivial task, and frankly intel should be able to do it, but it seems to be above HTC right now.

I would say the first issue is your CPU. It's well under the minimum requirements:

Re: Choppy Performance with Wireless Adapter

There we go. doesn't matter. A 4590 is only marginally better than a 2500, especially clocked up to 4.2GHz. Back in windows 7 I have about 40% cpu usage (and vr tours is using nothing while compositor is at about 20%) for the same settings, same hardware, etc. and wired headset. Seeing as people with later processors are all having the same problem, I'm not even remotely confident that upgrading the processor will help, especially considering how good performance is wired. I just got done playing 2 hours of serious sam 3, which has much better graphics than most VR games right now, without a single stutter the entire time. Screen time was in the 6ms realm and processor usage was as I said, 40% max. It could bottom out around 30% or so.

 

In other words, my cpu is already "well below" the spec for VR with Vive at all, yet my performance is way above average. It's not the CPU.

Wonder if the update will fix any of the problems.

Re: Choppy Performance with Wireless Adapter

I have tested the update in situations that commonly cause trouble for my wireless adapter.

No change in performance. The image still pixelates heavily and framerate drops from 90 to 25 in complex scenes, with audio becoming choppy and the pass through camera crashing.

Time will tell if the update improves general stability of the connection and reduces momentary/permanent drops to gray screen.

@Maribel_Hearn
Are you also seeing CPU spiking/maxing out during those performance drops?

Re: Choppy Performance with Wireless Adapter

I am not. CPU usage sits pretty low, as I am playing VRChat, which doesn't use a lot of threads. (i7 8700k at 5.0GHz, GTX 1080)

The pixelation/audio stuttering only occurs when I stare at very complex scenes, with lots of repeating lines or detailed textures. You can see my detailed write up here: https://community.viveport.com/t5/Technical-Support/VIVE-Wireless-Adapter-and-Supersampling/m-p/2377...
But this issues still occurs in some situations with super-sampling at 1.0, for example staring at complex grass textures, or a wireframe render of a scene with character avatars.

Re: Choppy Performance with Wireless Adapter

Installed the update.....while it seems it might have improved things a bit...sadly it is still not right for me. I can play on my Vive Pro wired for hours, but still with wireless, things feel weird quickly. And I still notice judder, maybe not as much, but it’s still quite visible. I was led to believe the only downside with wireless would be occasional reduced resolution. There is a lot more than that going on. And they should have some way to submit debug info to them.

Re: Choppy Performance with Wireless Adapter

Build a whole new system for wirless to run.. now on i8700 and asus maximus x motherboard.. first it seemd to work but i can now see pixelation again.. it is not as bad at it was before but still there...

 

Vox machina is unplayable still 100% CPU ... other tested games are fine at the moment but not as good as without.. What are you doing HTC.. My System is now some of the best you can have!!!!

Re: Choppy Performance with Wireless Adapter

An update to my previous post where I said the firmware update did not improve pixelation when staring at high-detail scenes...

The firmware update also seems to have had no effect on random temporary/permanent drops to gray screen. I still drop to gray screen randomly when diving into/out of menus, despite not losing line of sight to the antenna, and sometimes these drops are pemanent until I unplug and re-plug the wireless adapter from the battery.

@Amorgeddon

 

Can you list the specs for both systems so we can compare? I think at this point, it's not necessarily related to relative performance as it seems that some high-end rigs are being affected more than middle-of-the-road PCs. It may be related more to specific hardware units.
