A new hotfix update has rolled out for the Xbox One version of PlayerUnknown's Battlegrounds. The patch primarily addresses performance issues but adds a few more features from the PC version of the game--such as BP exchange--as well.

The update mostly seems to be targeted at addressing the framerate issues for PUBG when playing on Xbox One X. Both resolution and texture quality remain the same, but graphical settings have been toned down. You might notice a slight drop in quality when it comes to shadows and reflections but everything else should appear mostly the same, and the game should run more smoothly on Xbox One X. In order to address input lag while in the lobby between matches, the Customization menu has also been updated with an optimized inventory system.
