Re: Choppy Preformance with Wirless Adapter

I've submitted a ticket for support/return.  Maybe if enough people return it it'll get some more attention.

At least I would like to know if they are working on the problem and if there is a software fix or not

Re: Choppy Preformance with Wirless Adapter

@Synthesis 

In talking to one of your support members on a chat, it occurred to me that my motherboard, while having two PCIe 3.0 slots (PCIE1, which is a 16x/8x dual channel 3.0, and PCIE3, which is an 8x 3.0 linked to PCIE1), does not have two independent PCIe 3.0 slots. When I tested putting my GPU in PCIE1 with the wireless card in PCIE3, the lag was even worse than having the wireless card in PCIE4, a 16x 2.0 slot. After a bit of research, it turns out that if anything is plugged into PCIE3, the motherboard goes into 8x/8x mode because there are only 16 total lanes, which means the wireless card is now eating half the lanes that my GPU would prefer to be using, severely reducing performance.

 

I think this is the missing piece to the problem, which really should have been caught in testing. More or less, your system requirements are wrong, only users with a motherboard holding at least two completely independent PCIe 3.0 slots can use your device in its current state. I'm really hoping you can fix this if it turns out to indeed be the problem, because I can't afford to upgrade my motherboard (and by extension CPU) to match your requirements at this point, and I truly do not want to have to refund my wireless adapter after waiting for it for so long...

 

For other users in this thread still suffering the problem, do you have only two 3.0 slots, that share lanes with one another?

Re: Choppy Preformance with Wirless Adapter

That sound logicly and all evidence points in that direction. You either need a very strong cpu or a pci 3.0 Slot .. Well HTC cant admit it because it would screw over thousends of customers who meet the mininum specs or like me even far exceed them but dont have a i8700 or 2 pci 3.0 slots...

Re: Choppy Preformance with Wirless Adapter

I’m interested to know how many of these issues are caused by PCIe compatibility issue vs the amount of processing power used in wireless mode. 

 

I have choppy performance too, but only on titles that generally use a good chunk of the CPU. On my 4790k @ 4.7Ghz, I can run thinks like StramVR Home and Job simulator without problems, with resolution overridden to 100%, using a Vive Pro.  The same settings will cause stuttering in the made room of The Lab and massive stuttering in Nvidia VR Funhouse. 

 

Looking at CPU utilization, the stuttering is definitely caused by drastically increased CPU usage. 

 

I have to imagine there are further optimizations HTC can make on the wireless software. This just seems way too inefficient.

Re: Choppy Preformance with Wirless Adapter

Hello all,

NO PROBLEMS with the Wireless Adapter here, just thought I'd post my mid-range specs and hopefully it may help out with troubleshooting:

 

ASRock H97M Pro4 (This board only has 2 PCIe slots, both are x16. Wigig plugged into a PCIe x16 2.0 slot)

Xeon e3-1231 v3

16GB 1333

EVGA 1070 SC

 

As mentioned above, I've only got 2 PCIe slots. The 1070 is in the primary, the Wigig card is plugged into the only place it can go on my board. The ASRock site shows this as a PCIe x16 2.0 running in 4x mode. 

For additional details, I've made a Reddit post detailing the experience. Good luck I hope y'all get yours working

Re: Choppy Preformance with Wirless Adapter

So is anyone even looking into this anymore? Because I can assure you this is not solved for me, and I haven't heard from anyone since before my last post. At this rate I'm going to just have to refund the wireless.

Re: Choppy Preformance with Wirless Adapter

I have since not had much chance to test other things, my hopes are that i will be able to very soon. All i will be testing though is is a PCI-E x1 riser cable into the slot covered by my graphics card in hopes that will work and that the riser will fit underneath. Other than that i am out of options my end.

I hate to say it, but I have little faith any improvements will be made, other than potentially fixing the AMD specific issues.  I'm hoping to grab a 9900k this weekend, so hopefully that'll give enough horsepower to drive the wireless adapter.

Re: Choppy Preformance with Wirless Adapter

I was using the PCIe 3 x1 slot above the first GPU PCIe x16 (other 2 are covered by the video cards) and had this same issue.

Plugged it into the bottom PCIe x16 (3rd) slot and issue is gone.

  • 3 x PCIe 3.0 x1 slots

Re: Choppy Preformance with Wirless Adapter

Same issue as you all... choppy performance.. SteamVR reports tons of reprojection occuring. I am almost at my wits end.. and will try reloading Windows 10 64 bit from scratch this weekend before giving up and going back to wired and returning the wireless adapter.

 

CPU: i5 6600K

MB: ASRock Z170A-X1/3.1 LGA 1151 Intel Z170 SATA 

GPU: Nvidia Gtx1070

Tried all slots, removed every program from Windows I could.. got all bars in the wireless app.. yet I drop frames. Ugh!

Re: Choppy Preformance with Wirless Adapter

Well, I was finally able to resolve the issue on my end. It's not going to be the solution you want to hear, but I wanted to share. Again, these were all brand new parts except the GPU:

 

ASRock Z370 Killer SLI/ac

Intel Core i5-8600K @ 4.6GHz

G.SKILL 16GB DDR4 3000MHz

EVGA GTX 1070 SC

Clean Win10 install on SSD

 

I tried every since PCIe slot, and the issue was the same. Works perfect when wired, choppy mess when on wireless. CPU and GPU both around 50% utilization. Bought a second wireless adapter, still the same issue. Finally I decided to try a second new motherboard, and went with the ASUS ROG Maximus X Code. Installed the wireless adapter in PCIEX1_2 (just below the GPU), and everything works beautifully. No tinkering, no BIOS changes, just installed the wireless software and everything works perfect. It truly is a beautiful solution once it actually works. I've put in 2-3 hours a day since I installed it on Tuesday (3 days ago), and haven't had a single problem.

TLDR; Changed out my already brand-new motherboard for the ASUS ROG Maximus X Code, and now it works seamlessly.

Has everyone run a benchmark test? If the motherboard was really the problem, the GPU performance was probably not great either. This might be a way to tell if that's the issue (though it could also be the power supply as well.)

Thank you,

If your base station has a Fault 02/03 error or a red light or both, the ONLY solution is to contact our support on vive.com and set up an RMA. There is no user fix for this issue.

Re: Choppy Preformance with Wirless Adapter

I ran the SteamVR Preformace Test while I had the issue and it reported no performance problems.

Re: Choppy Preformance with Wirless Adapter

I installed the new update for Vive Wireless and it is now MUCH improved and working probably exactly as it should be. I tried loading up a few games and I think I am a happy Viver again. I'm thinking it must have been a conflict between drivers, hardware, etc... that the newest update fixes.. as I tried EVERYTHING short of replacing hardware. And yeah, mine pegged the VR READY status too, lol! 

 

Anyway.. good luck peeps.. Hopefully the new update fixes your issues or the next one will. What was so frustrating for me was, even people with extremely new systems had this issue.. so you took a risk buying your way out of it. I just hope my issues with wireless are behind me, as I didn't play long and still need to hook back up the old Vive connector box so I can use the phone connection. But I wanted to spread the word that after the new update to VIve Wireless.. I was able to play for awhile with no real issues. So don't loose hope..
