This video measures the frame rate of Gran Turismo 7 running on the PlayStation 5 Pro.
This test is done with 120 Hz, Ray Tracing and PlayStation Spectral Super Resolution (PSSR) enabled. You can find the video below:
As you can see, the game is able to maintain a frame rate of more than 100 fps a vast majority of the time during gameplay.
The fps can dip during replays, especially during the beginning of the race when a lot of cars are close together. With that said, it is still well above 60 fps. Overall, GT7 is one of the best showcases for the PS5 Pro.
