I hadn't used mine in a while and went back to it recently. I must admit I'm having a lot of fun and it does seem to have improved a lot but I think it's only because it's my only exposure to VR and I have learned to compensate for the poor performance of the cosmos. It still lets me down quite often but at least the controllers recover tracking a lot quicker now..
Seeing this explains so much and makes me so damn sad. How can the performance be so poor when so many other inside out can do so much better. What an expensive dud, I only hope they keep supporting it long enough that I can get enough hours to justify the cost.
Certainly won't be doubling down on the faceplate, lighthouses and controls from HTC now just to bring my cosmos up to minimum performance standards, I'll just go all in on Index when they finally become available here (in Aus too).
