Recently, some players accidentally discovered that the PS4 version of The Last Of Us 2 can lift the 30 frame limit by resetting the display settings and reducing the film grain effects to the lowest. This may be a legacy BUG of the PS5 version of the high frame patch.
After the frame limit is lifted, the frame number of the game will fluctuate around 35-50 frames, which is not very stable, and the fan noise will also increase.
