Comcast reported that its Xfinity X1 Enhanced 4K feed (with Dolby Atmos and Vision) was the fastest feed for any streaming provider and that the feed was only 14 seconds behind the live action.
That data showed that if you wanted the fasted feed with the least lag, the over-the-air Fox broadcast was your best bet (11.5 second lag), followed by Xfinity XI Enhanced 4K feed (14 second latency). Fox’s Tubi was a reasonably close third with 17 seconds latency. It also offered a 4K picture.
