The minor frame rate drops when running in the 60fps mode on the Xbox Series consoles were only found in some matches. The severity of the frame pacing issues on the Xbox One consoles varied without an obvious cause.
The Xbox Series consoles appear to be using Variable Rate Shading which can result in some double width and double height pixels being visible in the frame.
Xbox Series X and Xbox One X have performance and quality modes available but there doesn't appear to be a difference between them at the moment. The 120fps modes are accessible by setting the Xbox Series consoles to output at 120hz.
