I won’t keep you waiting any more: on the PlayStation 4, Gran Turismo 7 looks and plays just fine. While I testing the game on a PS4 Pro, there were several moments where I literally forgot I was playing on the older hardware. It’s not a totally equivalent experience, though, and the game doesn’t look as crisp and clear as it does on the PS5. There is also no ray-tracing at all in the PS4 version, which is another reason for the drop in visual fidelity.
Frame rates on the PS4 version were a bit of a mixed bag that I cannot entirely explain. I put my PS4 Pro through what I thought would be a “torture test” — a 20-car custom race with “Professional”-level AI, at night, in the rain, on the Nurburgring. It passed with flying colors. However, another race at a sunny Maggiore saw a noticeable and annoying drop in frame rate around certain parts of the track. I noticed it generally occurred when the far horizon was visible and draw distances were at their longest.
Of course, the base model PS4 can only run the game at a maximum 1080P resolution. The game still looks and plays well, but the drop in resolution was obvious.
