Turbo Prop Racing (also known as Rapid Racer) was significant in that it was one of the first PlayStation games to take full advantage of the DualShock controller; not only did the game allow steering with the analog sticks, but the gamepad also vibrated during a gameplay. The intensity of the vibrations also depended on what type of water the player was in; calm rapids meant low vibrations, while heavier rapids gave high vibrations. One of the game's biggest selling points was that it ran at 60 frames per second. However, in order for the game to run at that frame rate on the original PlayStation, track detail and textures had to be sacrificed. Additionally, the frame rate lowered to 30 frames per second during 2-player splitscreen. After reaching a certain point in the game, players could unlock Fractal Generator. This feature allowed the player to select from a large number of tracks besides the normal six. Players could either allow the generator to randomly create a number (which corresponded to a certain track) or manually input their own. While this feature sounded like it gave a staggering amount of tracks, in reality all these randomly generated tracks were basically empty aside from water and walls and as such, many of the tracks tended to run together.
