With the help of a few mods.
As you may know, Bethesda has made it possible to add mods to the Xbox version of Starfield thanks to the Creation Club tool. There are already several options to choose from, and people are busy creating new ones, with some pretty amazing results.
One such example is offered by Fuzion Xbox Testing. Starfield received some criticism before its release after it was confirmed to run at 30 frames per second. This was recently increased to twice that, but the Xbox Series S has no such options.
