The Xbox Series X and S are getting performance-enhancing AMD tech. The GitHub page shows devs can use either the new “Lite” model or the full-fat one, though “Full” has up to a 5.2ms performance hit on the weaker Xbox Series S. That’s enough to cut a 60fps game down to 45fps, not that gamers will see that: devs can cycle through each FSR mode and pick the best balance points between quality and speed.
