Hi, I have a Cosmos with the Wireless Adapter and have not had any problems installing Beta updates or reverting to Public Updates.
Just to let you know I'm currently running the public 1.0.10.7.
I must admit I'm enjoying the Freedom of wireless. I'm beginning to quite like the Cosmos. Though it can be frustrating at times.
I have recently started playing the Game A4 Tech in Viveport and the Bow and Arrow setup works much better than I had expected. The tracking is surprisingly accurate. The Bow can lose tracking a bit and go wonky if I pull my hand when drawing the arrow very close to my face, but I can reload and fire accurately. It's actually quite enjoyable to play. I think tracking is definitely improving.
On Monday I somehow managed to click on the order button within 30sec for a valve index. I hadn't expected to get it. I am quite intrigued by all the stories of its performance/display/controllers. Sad that it is cabled and not wireless. The Cosmos really does have its advantages. I can't yet make up my mind wether to keep index or not? It would have to be fantastically good to keep a cabled index? Any thoughts? Expensive though?
On a final note I was, up to this Monday having difficulty running Beat Saber on my System. For some reason and I'm not totally certain why it is now running smoothly and fast with excellent tracking. I removed the Windows update ending I think *996 and uninstalled steam and cosmos software. I then reinstalled steam and cosmos software. It then worked. Fingers crossed I don't jinx it by saying anything? Haha!
