For Christmas my wife gave me the wireless adapter to go along with my Vive Pro and it spun off a series of bug hunts. While the Vive Pro worked seamlessly on my previous system, the wireless adapter just gave it fits. I final caved and went all in on an upgrade. 9900K, MSI 2080, Gigabyte Auros Master Z390… I figured this would solve any horsepower issues.
Once I had it built and stable I had great visual performance….. except an annoying stutter every 10-15 degrees of head rotation. As long as I remained still everything was gorgeous. If I looked around the little hitch popped up no matter what.
I went through every post I could find and tried everything under the sun. Different ports, rebuilds, beta drivers, old drivers. Every single time same exact thing.
Last week I underwent some surgery which required bed rest and finally this weekend I felt ok enough to sit around in the chair for an hour here or there. I went back through everything. I finally found that if I placed the wireless adapter in my x8 port everything went away. Sadly, that cut the 2080 back to x8 as well. If I reduced graphics quality everything ran fine. I tested this back and forth and found it did “solve” the problem.
Tonight, I tried out the latest BIOS beta which I somehow missed back in January. Well I probably skipped it as it is beta and the only note posted on their site was “Support 32GB UDIMM”. Since that didn’t matter, I probably just saw it and forgot.
Well….. F8e bios to add UDIMM support also seems to address some PCI lane mapping, compatibility, whatever issue as well. Now my wireless adapter works smooth as silk no matter what slot the wireless adapter is in.
I’ve rolled back my OS to prior to this bug hunt quest removing every other tweak I made, and I’ve found nothing else at all impacts the jitter issue. It is now smooth as silk in a few games I’ve tried
