Finally, systems are powerful enough for 60fps.
PUBG next-gen

The PUBG Console Team just revealed some of their next-gen upgrade plans for PlayerUnknown's Battlegrounds (or PUBG for short). Thanks to the increased power of the Xbox Series X and the PlayStation 5, PUBG will now run "up to" a lovely 60fps, which has been a long time coming for home consoles.

This also means that PUBG will be playable on the Xbox Series X|S and PlayStation 5 from day one of each console's release. There will be no extra cost to current console owners of the game to make the leap to next-gen. Furthermore, all purchases made on the current consoles will make the move over to next-gen without issue.

The PUBG team also says that they are supporting cross-gen multiplayer alongside cross-platform play. This means that those on the Xbox One, PlayStation 4, Xbox Series X|S, and PlayStation 5 will be able to team up together or go against one another in the same game environment.

Specifics about the next-gen upgrades can be found below.

On the Xbox Series X, the game will run at 60FPS if you select the "Framerate Priority" option. The Xbox Series S will be based more on the Xbox One S build, which runs at 30fps. The team says they are "working to provide an option to raise the framerate cap on Xbox One S and Xbox Series S consoles in the future." Bummer.

As far as the PS5 is concerned, the game will make use of the PlayStation 4 Pro build. Again by using the Framerate Priority option, the game will run at "up to 60fps" on the PS5. This option will be available as part of the October 9.1 update for the game on both the Xbox One X and PlayStation 4 Pro.

So from what I'm reading here, only the PlayStation 5 and Xbox Series X will get close to 60fps. Not only that, but it sounds like the 60fps isn't locked in but rather will be a new upper limit for the new consoles.
