Hi guys. So 2 days ago, I noticed how my YouTube is very heavy. I guess YouTube went through an update? or something that causes computers to use discrete graphic even on low video quality (240p, 360p, 480p). Usually, or last week, my Mac would only use discrete (AMD Radeon HD 6750M) on videos up to 720p. Im not sure if this is YouTube's problem or my Mac's but Im guessing YouTube. My activity monitor shows how stable my computer is. Safari itself is only using about 300MB and plug-in is about another 300MB. When I try so skip parts in the video, it lags and sometimes it stops processing the video so I would have to reload the page. During these activities, my Mac also lags. Safari freezes (beachball), mouse cursor disappears, missioncontrol lags, pretty much everything. So, am I the only one who is seeing this when visiting YouTube? To me, this doesnt happen on any other websites. Thanks in advance.
