PUBG Corp. has released a new update for PlayerUnknown's Battlegrounds on Xbox One. Following its stint on the test server, patch #13 has been rolled over to the live game, although it's a fairly minor one, primarily making optimization and performance improvements.

Among other things, PUBG Corp. has optimized the parachuting and free-fall process, which the developer says will make the game run better during the early stages of each match. Additionally, world loading has been improved, while movement data for players who close by but out-of-sight is processed more efficiently.
