I dislike how certain individuals are playing down Mario Kart 8...
As I said before in other threads, it is unfair to compare Mario Kart 8 with Grand Turismo or Forza because different graphical direction and I do not mean artstyle. Vehicles in Grand Turismo and Forza are mostly not texture intensive since color of the car is just a single pixel so its not resource intensive as it would be with normal textures so its basically resource intensive as Virtua Racing or Virtua Fighter for Genesis/32X.
Its not memory nor processing power intensive asnit would be with actual textures rather than practically untextured colored polygons, it is a neat trick that allows you to use far more polygons that you usually would and GT and Forza have severe LOD for car models so maximum detail of the car you could see in GT and Forza would be ifit was few meters away and GT and maybe Forza uses primitive tesselation for LOD.
It is just bunch of tricks applied to make an illusion...
