Choppy video

NFL Game Pass features adaptive playback which dynamically adjusts the quality of the video stream you receive based on the speed of your connection. If your connection speed fluctuates (many factors can contribute to this such as network congestion during peak times and other devices sharing your connection) NFL Game Pass detects this and lowers the quality of the video stream to ensure you can continue viewing the content without interruption.

Make sure your computer is up to date with the latest patches and your video card's drivers are current.

You can also disable hardware acceleration as it can cause choppy video playback or increase virtual memory as it can improve video playback.
