This Seeking Tech article showcases the frames per second for the PS5 Pro Mode, with the frame rate unlocked, of The Last of Us Part 1. It contains several combat scenarios across various environments.
You can find the video below:
The footages were taken off-screen from a LG B4 OLED with the Google Pixel 6 camera.
For the most part, the game is able to stay comfortably above 60 FPS in Pro Mode. It only dropped below 48 FPS a few times for a second (the B4’s FPS tracker will show it as 120 FPS) before getting above the 60 FPS again.
Overall, the game should stay above 60 frame per second most of the time even in high stress situations.
