Gran Turismo 7 in a Digital Foundry comparison of all its versions

Thanks to the ability to save replays in the cloud and download them on any version of Gran Turismo 7 (PS4, PS4 Pro and PS5), Digital Foundry was able to make a perfect comparison between all the platforms on which the work of Polyphony Digital.

Replays, in fact, are not exactly recorded videos: they are game “action” that is rendered on the screen by the system in use at the moment, so a scene originally saved on PS5 will not be identical on PS4.

Generally speaking, the PS5 version shows up in Native 4KPS4 opts for the Full HD 1080p native and PS4 Pro is set to 1800p checkerboard, a compromise that both John Linneman and Alex Battaglia are satisfied with. The PS4 and PS4 Pro versions, however, don’t have big differences apart from the resolution: the base model has only a few lower quality textures.

The PS5’s GPU is roughly two and a half times more powerful than that of the PS4 Pro, and in fact its processing power doesn’t just increase the number of pixels. On PS5, for example, there is a lot more foliage rendered at a much higher quality, and even some trees look completely different models between the two versions.

Lighting is king on PS5: the simulation of light diffusion is much more convincing especially on reflective surfaces. Two things not present on PS4 are volumetric lighting and godrays, the latter being replaced by a bloom effect. Shadows naturally appear sharper on PS5, and blurrier on PS4.

Transitions in level of detail are more noticeable in the old-gen versions, a bit like car model detail, loading times and framerate wobble – the latter of course more on base PS4 than Pro.

Ultimately, Gran Turismo 7 is technically great on all systems on which it is available.
