Everything is running perfectly on my PC (rig in my computer setup), except for one thing. I can't run twitch stream on 1080p without lag. Even 720p is sometimes laggy. My connection's ping is 6 ms, and its speed is 50 Mbps download, and upload. Also, I have absolutely no problem with video streaming anywhere else. Youtube, and every other websites are fine. Is Twitch more demanding than most, is it my connection, or what else ?
