This beta update (184.108.40.206) made things worse for me. It introduced instability/compatibility issues to my Elite Dangerous game play. I was kicked out of the game at least five times during one session. It also brought back the low light warning to my Cosmos. These issues were absent with update 220.127.116.11. Controller tracking is worse not better in my case, particularly my right controller. To HTC Vive engineers: I Know this is not easy, but it is what you guys do for a living. Please get this tracking fixed as soon as possible without introducing unintended problems. We are all pulling for you. It is very much in our interest to do so. Best of luck and I hope you can make some real progress with controller tracking and eliminating unintended consequences with the next update.
