Link cable issue - VERY FRUSTRATED

Recommended Posts

Hi folks. Up until now I have been using AirLink when using VR. I decided to use a Link cable since I read a number of well respected people on YouTube saying that's what they do.

But, when I use a cable I get this weird ghostly background faintly all across the whole screen. It's not a double image or anything like that. It's just some kind of wavy ghost image.

Now, let me tell you what I've tried:

1. Two different cables, one being the official Oculus link cable and one being an Anker certified cable.

2. I have tried (with both cables) using the USB3 motherboard direct port as well as a USB3 port oln the front of the case.

I reall;y don't know how to troubleshoot this. I need help. The really frustrating part is that the image in general looks like it's quite clear. But I can't take advantage of it because of this faint wavy ghost interference of some kind all over the image.

Can anyone help m,e to know what to try to troubleshoot this issue. I don't have the issue when using AirLink but I want to see how my image and performance is when using the cable.

 

Thanks ............ Rob

Isn’t the Oculus official cable a usb C ,?  I use a C by Kiwi Design and it’s always been very good .  Have you done the speed test in the oculus app to see how the cables are performing ? 
 

I do get occasional crashes in the headset but I suspect that may be caused by Realtek sound river now and then but can’t prove that   and the odd “ wavy “ Image now and again but normally a restart of the headset sorts

Yes the cable is USB-C. I tried both USB-C ports on my motherboard and Oculus said they were really USB-2, not USB-3. So I put a USB adapter pon the cable and plugged it into a super USB-3 port on my motherboard. Then the Oculus speed test succeeded, indicating a data speed of 2.8Gbit.

However, the background interference is still there. This is driving me crazy because I don't know what else to try. I have reset the headset numerous times, tried different cables, different PC ports, etc.

I don't know what to do next to troubleshoot this.

Well, after reading dozens of different threads in different forums, I read an article about setting Link settings in the Oculus Tray Tool or Oculus Debug tool. I tried a bunch of different settings and finally realized that while you set the encode bitrate when using AirLink, you don't do that when using a Link cable. Once I set new values for the encode bitrate and maximum bitrate, the background interference went away and now I am getting some of the best graphics I have been able to get so far. Still a lot of tuning to do but at least now I don't have the issue I had before and I can move on to setting Open XR Toolkit settings, Oculus Tray Tool settings, and in-sim settings to maximize graphics and performance.

That’s good news.   It’s all very complicated !
