I can not understand SCS. For such a rarely used and basically unimportant function, an option is built in.
For important settings, such as the LOD distance you have to tinker in the Game Config File, there is no convenient and quickly accessible option in the menu.
The reduced LOD distance introduced with the 1.29 is awful, you see how the vehicle changes several times and the details are added. My video card is already bored.
