Choppy Preformance with Wirless Adapter

This is false that it's sovled.  For some it may have been some kind of PCI-E card slot issue but in general many of us are still having massive performance issues with the CPU being all over the place.

Posting to say that I believe I've mostly fixed the issue by moving the wireless pci express card to the third PCI 3.0 16x express slot (only operating at 4x). I'm pretty sure the first two PCi 16x work in tandem and share the 'lane' as a lot of you have said, but the third slot works fine. Before I made this change, elite dangerous was unplayable and even beatsaber had noticably lesser fps.

 

After the change Elite is more than playable however admittedly it still randomly blurs out for a split second, but its not literally every 1 second as it was before making me dizzy. I think now the problem is my CPU capping out at 100% which I can try and fix by lowering settings and what not. 


Chalk me up as another who fixed it by moving to a different PCi slot, specifically one of the 16x ones, and the one furthest away from the video card.

Well, here is an article from TomsHardware via reddit that explains that the problem most likely isn't your PC, it is the Vive Wireless Adapter itself. https://www.reddit.com/r/Vive/comments/9tnsty/toms_hardware_wireless_adapter_review_the_pc/

 

Vive should say something like "We are aware of the problem, and we will report back with an update on our progress by xx/xx/xxxx"

Guys try and see if your SteamVR workshop is in that stupid download loop that never downloads, maybe this is causing an issue, someone tried to run steam offline so it stopped it from trying to download load and saw a huge difference, maybe steam software is part of this annoying issue, i can't see why everyone with a kickass rig is having probs. i mean dam, the tpcast on the OG vive worked fine for me and a decent rig. I know they are totally 2 different setups but either the adapter and htc software is an issue or Steam is. I'm gonna try as well tomorrow cause mine was choppy but I was on a low end VR rig. But did see the workshop trying to download.

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.

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.

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.
