Let’s start off by discussing about the gameplay and graphics of these sim racing games. Both the games do an amazing job in producing every little minor detail to perfection. They did an excellent job in trying to create a lifelike scenario through virtual means. However, assetto corsa gains an edge over GT in this category. The details on the car interiors are superior to GT. Although the gameplay of Gran Turismo Sport is really good and smooth, assetto corsa has a better overall gameplay experience. The thing that seperates grand turismo from assetto corsa is the unreal engine used by the creators of AC, which produces photorealistic images that are not easily distinguishable from their real life counter parts. In Gran Turismo,it is easier to control the car.It also promotes overspeeding which is not a wise thing to do.It is much easier to turn through corners in GT than AC.AC also produces a more realistic sound than GT.However, the platform plays a significant role in this scenario.If you have a console(PS4 or XBOX), it is wise to choose GT over AC because GT provides a better gameplay experience on low FPS platforms than AC.Although AC has fixed their problem of having low frame rates,it still does not run that smoothly.
