I think that cb combinates something and sometimes we can choose manually 30 or 60 and sometimes just stream is in the FPS model set before and its just one for everyone. I was witness of situation when u could choose 720p, 1080 and so on and 5 minutes later that was not available- only option FULL SCREEN. ANd after next 2 mins everything back to normal ( of course during that time many models were in slow motion and site was shitty but uits nothing new that they combinates a lot, they change something and they make it back and then again. Things without logic .....
