This is the official "Realistic Driving" mod for GTA V. This mod features completely new driving physics, created from scratch for each of the 357 vehicles. The performance of each vehicle matches its real life counterpart perfectly.
Version 2.0 of the "Realistic Driving V" is almost finished. I worked for several weeks on tweaking the surface properties of all driveable surfaces and checking for unintended side effects (which always happen in GTA modding). Seriously, who would have been able to predict that increasing terrain resistance of loose sand would cap vehicle top speed on the highway at 90 kph. And how was i supposed to know that the shoulder of the road and dry gravel next to it are considered "deep, wet mud" by the game? Anyway, i got all problems sorted out, version 2.0 is about to be released.
