I just got a new Surface RT 64GB yesterday and started it up and went through all the tons of updates that needed to be done. I went to a couple sites and played some videos right on the sites and to my disappointment the videos were VERY choppy. Like sound did not match the video at all and it was so choppy bad. I tried at my rents house too just to see if it was the connection and it did the same thing. Video plays perfectly on all my other devices. Has anyone had this issue. and what was the fix for this? I made sure nothing was running in the background and like I said, it is brand new so not sure why it is doing this. It also didn't matter if it was full screen or not. Thanks in advance!
