Gran Turismo 7 is out tomorrow, and to give you an idea of what to expect in terms of performance, Digital Foundry has provided an analysis for the PS5 version.
According to Digital Foundry, the game’s checkerboard-like 1800p has been upgraded to full, native 4K since the release of Gran Turismo Sport. Along with a higher pixel count, images are enhanced thanks to texture filtering, shadow quality, reflection quality, and more. DF says that while it’s not perfect, it “goes a long way in reducing some of the visual artifacts that you can see in GT Sport.”
The game also features the addition of per-pixel motion blur during actual game play at full resolution, however, there are no lower resolution options that might have allowed hardware-accelerated ray tracing to be used in-game.
A key feature in Gran Turismo 7 is hardware-accelerated ray tracing, but you have a choice of using ray tracing or a higher frame rate. When using ray-traced reflections, the feature will be used in every scene that contains cars – except for the actual gameplay. This means replays and the menu system use the feature, but the frame rate is capped at 30fps, while disabling ray tracing removes the performance cap.
Ray tracing really makes car paint shine as the clear coat reflects light, allowing for realistic finishes across vehicles. With ray tracing reflections, the result is “more accurate because the paint reflects not only the environment, but also other cars and internal reflections.” When active, ray tracing is applied to all cars and they all reflect each other properly.
Cars are presented with a “high level of detail within the acceleration structure” meaning you can expect accurate reflections, especially in replays, but the performance hit makes it unsuitable for gameplay where polyphony is aiming for 60fps.
For ray tracing iterations, the frame rate is capped at 30fps and maintained most of the time. Replays “run very consistently and look great with RT reflections,” but gameplay stress test conditions “have a similar impact on replays,” causing things to drop below 30fps. Once the cars are spaced in a race, the problem goes away. While replays aim for 60fps without ray tracing, things are “mostly solid” but a “densely packed grid” mixed with inclement weather will cause dips.
Digital Foundry is currently testing Gran Turismo 7 on PlayStation 4 and PS4 Pro and will publish its results soon.
