Im having similar issues as everyone else in this thread. Vive Pro Wired vs Wireless is very different in performance. Wireless gets a lot of reprojection in complex scenes even when the cpu only at about 80% and gpu at around 90%. On the performance graph it shows as a lot of late start on cpu when I turn my head to more complex scenes.
System Specs,
i7 5820k @ 4.2ghz (6core\hyperthreading)
16gb Ram Kingston 3000mhz ddr4
RTX 2080ti
EVGA X99 Classified LGA 2011
SSD
I have tried all the common troubleshooing tips mentioned here and on reddit....Tried all PCIE slots. Making sure they are 3.0 in bios. Set SS to 100%, I also have a Rift so shut off any oculus software using tray tools, different wireless channels, steam vr beta etc.
Simpler games its fine and not noticeable, but in games like skyrim where I got little to no reprojection when wired I get a lot more frequent when wireless. Especially if I look at an area that has more detail and lighting. I love the adapter when it works, but hopefully there can be some software optimiztion that doesnt bog down the cpu as much as it does now.
I had a gtx 1080 and specifically bought a 2080ti in hopes that it would fix the frequent reprojection I was getting in wireless, but its pretty much the same as before. Its definately something going on with how the wireless handles the cpu.
