I am also having this issue.
I have just put together my dream machine specifcally for this.
I am so disappointed right now.
Symptoms: (none of these occur if I use a wired connection):
Constant greying and blacking out
Choppy graphics
Floor level different every time I start BeatSaber (Room Setup run countless times)
Laggy controllers
Unplayable games
Utter, utter frustration
System:
CPU (i9 9900X): 30 to 40%
GPU: RTX 2080 Ti: Barely used
Win10 Pro
32GB RAM
Conditions:
Clear line of sight from transmitter
Different connection modes tried
No other apps running
Camera and Bluetooth turned off
Windows, Steam and all drivers up to date
Vive Wireless shows 4 bars
I am struggling to see why Vive think it is acceptable to release such sub-standard hardware. This is a disgrace.
