But it lacks some of the tracks, has outdated visual quality and almost completely misses mid-season changes, and sometimes it crashes.ĭM's mod has top quality visuals (graphics and models), it has all the tracks, has unique pyhsics, andfollows the midseason changes in color schemes, driver lineups and most of the car part upgrades (different 3D models). The CK mod uses physics almost identical to the stock game, and thus, it is better balanced.
