It adds up to a great looking game on PS4 and Pro but one that can look significantly better on PlayStation 5 in specific sections thanks to these enhancements, even in the frame rate mode.Īll Ray Tracing is disabled in gameplay, no matter the choice you make in the menu.
The Planar Reflections used on car mirrors are also of a higher resolution, object density, and filtering. The volume of clouds is better and, although a minor boost over last generation it still adds load to the GPU. All these elements are cemented by the dynamic weather and cloud system allowing light in all areas to drastically change from sunny skies to overcast, rain, and more. Higher Foliage is used with better shading and again grounding within the world. This carries on outside with far more shadow-casting objects, higher texture details on grass, buildings, and roads, and improved asset quality. Self-shadowing is improved with far better and more accurate shadow filtering and ambient occlusion. The PlayStation 5 also offers other visual boosts over the PS4 and Pro versions. In a testament to how good these methods are here, they do a convincing job of emulating the same details to most players’ eyes. Although they run in replays and can be of benefit in certain conditions when cars are close together reflecting each other, they can also go unnoticed in other sections, with road reflections, building or even drivers’ helmets, all reverting to dynamic cube-map reflection or screen space reflections. The improvements that Ray Traced Reflections bring can be transformative, and are most easily noticed on the Garage view of cars, in car interiors, and in the Scape movies. This is a strength of the Ray Traced Reflections used here as they emphasize the micro-facets of the surfaces, allowing highly uniformed surfaces such as the chrome bumpers of a Mini to reflect the objects around it. The different reflective surfaces of the car each bounce and absorb light differently, bringing a realistic look that convinces us we are looking at chrome, leather, rubber, and so on. That includes Global Illumination for the bouncing of light from one surface to another, as seen when the striking red bucket seats of a Honda Integra bounce soft, red-diffused hues onto the leather steering wheel or the faux carbon fiber dash. The physically-based materials used in Gran Turismo are amongst some of the best in the business.
Being built on that engine means the same industry-leading HDR and lighting quality are present to deliver consistent and accurate cars and interiors that are convincing as they differentiate themselves with excellent micro-facet behavior and energy consumption properties. These were already convincing in GT Sport, and what we see here is an iteration or two further from that 2017 release. The PlayStation 5’s Ray Tracing hardware empowers Polyphony to increase the realism and accuracy of the car models and all materials.
