Choppy Preformance with Wirless Adapter

Re: Choppy Preformance with Wirless Adapter

For the people asking about PCI-E lanes.

Standard desktop Intel CPUs only offer 16 PCI-E lanes directly connected to the CPU.
The Intel chipset has many more PCI-E lanes to enable the use of expansion cards such as network cards, audio cards, storage cards, and of course, the wireless adapter's PCI-E card. Chipset PCI-E lanes perform a bit slower than CPU PCI-E lanes, but for most use cases, this performance difference does not matter.

Intel High End Desktop CPUs offer additional CPU PCI-E lanes. These would be CPUs like the socket 2011 i9-9920X.

@Maribel_Hearn  My CPU i7-7820X has 28 PCIe lines. I tried to connect the wireless card to the processor lines and to the chipset lines. No difference or difference is noticeable.

Re: Choppy Preformance with Wirless Adapter

Did steam vr make an update because I played with the vive wireless tonight and it worked flawlessly on 3 games. Smashbox which always has pixelation. Pavlov which is always buttery smooth. And skyrim which causes pixelated on certain scenes. I was staying between 30 and 50 on cpu. And 50 to 60 and max threads. Will test again tomorrow. Side note for u who haven't played smashbox. Best game in vr.

Re: Choppy Preformance with Wirless Adapter

i've been trying to get my Vive Pro working for months with Wireless with no luck, so last week I realized the onoe thing I didn't try was removing my M.2 drive. So I bought an SSD, took out the M.2 drive, Did yet another clean install of Windows and the Vive software, and my Intel i7 8700K, Z370 Mobo, GTX 1080Ti PC still was just as jittery as ever in wireless. So back again to wired I go.

Re: Choppy Preformance with Wirless Adapter

Volman13n0 - the last SteamVR update I see is Jan 22 but my experience is pretty much the opposite.

 

This seems like a very annoying / difficult issue to troubleshoot. I have similar specs as

 

,  Intel i7-8700K 3.7 GHz, Z390 mobo, 16GB RAM, SSD, nvidia RTX 2080. Had the VIVE Pro for about a month and has always worked perfectly with no issues using wireless until about a week or so ago...right around the last SteamVR update.

There have been no changes at all in my physical enviornment, placement of hardware or anything related. Wireless signal shows full. Only changes since then may be video driver and Steam VR updates.

Games that used to run without issue are often choppy and I get periodic freezing or stalled Steam Home loading and general flickering in the display. Not always constant as sometimes will run fine for some minutes then flickering starts again.

I've always hasd one "stubborn" basestation that doesn't seem to get registered when SteamVR is loaded until I move around a little but placement and angles seem to be right on.

@Volman13n0 Are you on a Vive Pro or OG Vive?  The majority of people having performance issues seem to be on the pro it seems.

Re: Choppy Preformance with Wirless Adapter

This is a super interesting post on reddit. The user has 2 identical machines. One works with wireless, and the other doesn't. HTC should either indicate that they have exhaused all troubleshooting and are confident there products works as expected, or they should be reaching out to people with experiences like this to figure out what the issue is.

Re: Choppy Preformance with Wirless Adapter

Saw that. It is interesting.

My PC specs are identical except for mobo which is very close as well.

My experience for about a month was like his machine with no trouble and then suddenly, problems.

I haven't tried a wired connection as I really don't want to use the system that way but maybe I'll have to see if that helps eliminate other causes.

Re: Choppy Preformance with Wirless Adapter

ok so heres the thing i have both vive and vive pro headsets

same machine used for testing

asus x99-a motherboard

i7 5820k cpu (not OC'd)

RTX 2080 Graphics

32 gb ram

 

All pci-e slots set in BIOS to use full speed. Not auto.

vive pro has issues with low res and choppy

vive standard no issue whats so ever...even at 200% SS

as a side note the pro works ok sometimes but does have an occasional glitch of low res and choppy.

also i stream vr games on mixer and twitch and as soon as i open OBS with the vive pro its unplayable....not so with the vive standard. Flawless.

 

Make from that what you will im over it. i want my pro to work as intended or the adapter will be going back. HTC need to admit there is an issue now and make sure they look after the people that keep them afloat with these expensive purchases.

Re: Choppy Preformance with Wirless Adapter

Same problem here, got the adapter 2 days ago for the VIVE.

 

ASUS PRIME B250-PLUS

I5-7400

GTX 1080

8 Go DDR4

 

Use to worked great while wired, huges lag and poor graphics using Wireless Adapter. I tried various PCIe slots, same everytime. Also tried the BIOS Uptade, and forcing PCIe slots in Gen3.

 

If changing the motherboard is the answer, i'm not ready to put another 300€ in it!

Re: Choppy Preformance with Wirless Adapter

Came here hoping for a solution but only see other VR fans having the same issue :( Bought mine a week ago and fail to get it to run properly due to my CPU hitting 100% immediatly after starting steam home or any other VR application. I was running 150%-200% supersampling wired easily but can't even manage 80% on wireless. Even standing still is causing frame drops. 

 

Asus Maximus VIII Hero (tried all 3 x PCIe 3.0 slots)

I5 6500

GTX 1080 TI

16Gb DDR4

Samsung 950 Pro NVME

 

I have all latest drivers, BIOS, updates, the works. I installed my PC from scratch this weekend but to no avail. I need to know if this can be fixed in the software since I read people with i7's also having this issue. If not I need to know in time for the return policy.

Re: Choppy Preformance with Wirless Adapter

i had this with my i7 7700k. but i read somewhere changing the power performance to balanced, and it seemed to fix it for me. but its still early days.

Re: Choppy Preformance with Wirless Adapter

@Traxas83  If you are not ready to replace the motherboard and processor, return the wireless adapter and continue to use the wires.

I have achieved good wireless performance on my configuration:

 

CPU i7-7820X

ASUS ROG STRIX X299-XE GAMING

Samsung SSD M2 970 Pro 512Gb

RAM 32Gb Quad Channel

MSI 1080Ti

HTC Vive

Windows10 64bit

Any idea where you read this? Haven't heard this solution before...
