I am a chessfan and follow every great chessmatch. On Chessbomb.com there is going several great matches just now and last evening I had one of them open for serveral hours. GRENKE Chess Classic 2019 I follow not only one fight, but like to move from one to another "checking" their current situation and what I would have done in next step. As I am still checking my new wireless broadband investigating what data-limit I should use/pay for, I checked the data use for the last days and found large numbers. Digging deeper in the data use I found twitch.tv which after more googling is found to have very much streaming all around the world. I have earlier found Chromecast to be one of the big data users, but changing from HD to SD it went down from 3-4 GB per movie to 0.7 GB. Chessbomb/twitch.tv don't use som much as HD, but between HD and SD. My question here; is there a method to use less data on chessbomb/twitch.tv also? Without logging out of it.
