A new update is now available for Rise of the Tomb Raider on the PS4 version of the game. It is version number 1.06.
The patch notes are:
Improved frame rate stability
Some minor bugfixes
Rise of the Tomb Raider was recently updated also to be played on the PS4 Pro console. You had the option to play the game in 4K, it stick with a 1080p and 60fps option.
Even though the game came out last year for Xbox One and Xbox 360, the upgrades it received for PS4 Pro owners made it worth the long wait for it.
