Update 25 is a nightmare. I couldn't use it at all for a few days as it didn't except a boundary. I can use it now but it stutters sometimes. Biggest problem is that I get a bit motion sick from games I play for 2,5 years without any problem. Even when I just got my first hmd I could play rhythm games. After update 25 I can only play for 25 minutes. I don't know what they did but it's a nightmare. Customer support took over a week and the only thing they can come up with is factory reset. Clearing boundary cache made it possible after several attempts to kind of set one. As soon as I go into boundary setting it flickers, moans and gives me partial black screens. Also tracking is off the last week. What the hell did they do? That motion sickness is killing the experience.
