There have been few issues surfacing in a few of PlayStation 4 Pro titles, which fans are hoping that Sony will address in the soonest possible time. It concerns customized Pro functionality, which can only be accessed if there is a particular display attached or when the display settings of PS4 Pro are configured in a specific way.
"Dishonored 2" and "Call of Duty: Black Ops 3" have alerted Eurogamer on this issue and "The Last Guardian" is the newest title to introduce two different performance profiles without providing users to choose which one they need to access.
For instance, when "The Last Guardian" is booted and set to 2160p output with the Pro will give a higher resolution but when running the game at 1080p video output, a different mode is accessed, which is the full HD output with a superior and stable frame-rate.
Once "The Last Guardian" lags, users can seriously feel it. An example is where an area playing out at 23fps on PS4 Pro in its 4K output settles ideally at 30fps when played on a screen with 1080p video output and the Pro's higher resolution mode provides a considerably less firm experience than the 1080p mode throughout the game. Digital Foundry has the detailed steps to get a smoother performance of the game on PS4 Pro on 4K screens.
To ensure a largely consistent performance level for "The Last Guardian" on PS4 Pro with a 4K screen, go to Settings, choose Sound and Screen and access the option for Video Output Settings and choose the 1080p option. Boot "The Last Guardian" and it will guarantee that the game boots in the performance-orientated 1080p mode.
Additionally, in the game's progress, nothing will stop users pressing the PlayStation button on their Dual Shock 4, revisiting the option of Video Output Settings and re-selecting one of the options of 2160p for 4K displays. "The Last Guardian" will only check what mode to use when trying to boot the game, thus, the profile it uses will not change when swapping video outputs even after it has loaded.
