Choppy Preformance with Wirless Adapter

Re: Choppy Performance with Wireless Adapter

Skaliligman-

Could you tell me what PCIe version your X4 port is operating with?  The guys at VR Freaks on youtube mentioned that when they forced their port to V3.0 instead of V2.0 they saw a significant improvement.

 

You can check the PCIe version 2 ways:
1)  In device manager, find the intel wigig VR device, under the details tab select 'PCI express spec version' from the drop down menu.  (Mine is operating in 2.0, with some degraded performance in complex games)

2) I'm also using the HWINFO64 utility to get a bit more information quickly.

 

Thanks for checking,

Jeff

Re: Choppy Preformance with Wirless Adapter

Morning John-

Have you noticed any reports of the PCIe version affecting performance?  The guys over at VR Freaks on youtube mentioned if they forced their PCIe version 3.0 they saw a significant performance issue that permitted them to run Fallout 4 VR smoothly.  I've confirmed my system is running the card at V2 and currently has issues running FO4 to where its unplayable.  Games like the Lab and RecRoom have little to no issues.

 

Looks like my BIOS won't let me force the slot/card to V3, or I'd give it a try myself.  Do you know of how to force the card to operate in V3 within Win10?

Re: Choppy Preformance with Wirless Adapter

RE: The PCIe express lane theory.... Myself and many others in this thread have already proven that the PCIe lanes are not the cause of these problems. Of course there would be performance increase using 3.0 vs 2.0, that's not why we're here.

 

ASUS Prime Z370-A II - I have tested the wireless card in 4 different PCIe 3.0 x1 slots, and in one PCIe 3.0 x16 whilst my 2080TI was fitted in the other, both 16x slots were confirmed to have been downgraded to 8x during testing. ALL of the performance testing I performed previously were in the 8x/8x configuration.

So no, 2.0 PCIe nor "PCIe lane shortage" ? What the ? isn't the root cause.

I would REALLY, REALLY love to see some performance analysis figures from people without these problems. Maybe everyone has 100% CPU lock overhead and just haven't noticed? Can we get some Wired VS Wireless CPU/GPU utiliziation compairisons from a fully operational system?

Vive Team ? Can you provide this data? Expressing to us what the normal/desired operating figures are.

Re: Choppy Preformance with Wirless Adapter

I just had a conversation with Vive tech support.  This is what they told me.  I haven't yet tested because I'm in the process of moving, but hopefully this works for some of you.

 

Hello John!

I hope you had a great day.

This is the email promised about the possible fixes for the image quality with the wireless adapter. This was a public release, so you are able to find this information on Steam website.

This article basically showed the wireless GPU performance improvements with the recent SteamVR update. So, I would recommend you please contact Steam support in order to see if you already have the most recent update that should fix these troubles https://help.steampowered.com/en/

-The most recent SteamVR update Fixed Vive Wireless Adapter GPU performance issues

-Fix for extended running start in async mode:

The compositor will dynamically pull back running start to accommodate apps which are CPU bound on their submit thread. However, there was a driver bug which was preventing this from operating correctly much of the time. This change switches to a more general approach which avoids this issue. This now allows the compositor to provide up to 8ms of running start on both Nvidia and AMD hardware, although it is a Windows 10 only feature. If you have previously relied on disabling async-reprojection and enabling “Always-On Reprojection” in order to play racing and flight sims, please retest with this. You can monitor running start timing using the SteamVR Frame Timing graph by looking at the black “New Poses Ready” line in the Details view.

-Allow developers and advanced users to disable all async and reprojection features by pressing Shift+A in the mirror window. This setting will persist until SteamVR exits to avoid customer’s accidentally disabling async persistently across launches of SteamVR without knowing how to re-enable it. A message will be displayed in the upper left corner of the mirror window notifying you that async and reprojection have been disabled. Pressing Shift+A has the same effect as disabling async, disabling interleaved reprojection, and enabling “always-on reprojection” (which just gives a full frame of running start to the app) in older versions of SteamVR.

-Fixed prediction for secondary "game" poses when going into and out of throttling.

-Moved Direct Mode settings to their own group to support multiple headsets.

-Fix for constant dropped frames reporting and erratic timing when NvAPI display timing call fails.

If after updating SteamVR until the latest version the issue remains, please contact us back through the chat as I won’t be able to follow this interaction via email. So, we will be able to continue with troubleshooting or explore the warranty options for the adapter.

Re: Choppy Preformance with Wirless Adapter

I'm using a gtx 1070TI and have HORRIBLE picture quality compared to when I'm plugged in - when using wireless.. I just got mine today and am trying to figure out if this was just me.. but I guess not. my 1070TI should definitely not be making BEAT SABER look like a ps1 game though. . It looks fing AMAZING when plugged in. . this is a shame. Thinking of returning wireless adapter immediately, as this is unacceptable for $300. And I even notice some latency here and there when it's suppose to be 0 latency.

Re: Choppy Preformance with Wirless Adapter

Can we get some clarification on what exactly is causing pixelation, audio stuttering, and absurdly low framerates?

How is the video stream compressed, and where? Is it done by the PCI-E card? Is it done on the CPU? Where is the bottleneck? Is the bottleneck the HMD mounted wireless adapter not having enough horsepower to decompress the video stream? Why does supersampling cause the image to become compressed and pixelated?

Re: Choppy Preformance with Wirless Adapter

THERE IS NO SOLUTION! the wirels adapter it's crap! wont run good even on a i7 8700, 1080ti!!!!!! I tried every single "solution" and nothing, of course light greaphinc games they work good, but go and try a good game  and bum, everything looks like this and pfs goes to **bleep**.

 

DONT BUT THIS CRAP!!!!!!!!!!

Re: Choppy Preformance with Wirless Adapter

I'm having the same issue. Experience is very choppy, with sporadic pixelation and stuttering with audio glitches.

 

  • OG Vive
  • Core i5 7600k @ 3.8Ghz
  • Gigabyte GA-H270M-DS3H
  • 8GB RAM
  • GTX 1080
  • Win 10 pro 64-bit

 

Tried everything in this thread. Feeling like I just threw $300 down the drain, which is not a trivial amount of money for me at all.
