With AC 1.14.1, Kunos focused on backend stability and CSP compatibility. While newer CSP versions work, 1.14.1 remains a favorite for lightweight, crash-free modded servers.
Note: If you have the Steam version, you are automatically on a build newer than 1.14.1, but modders use "1.14.1+" as the baseline requirement. assetto corsa 1.14.1 mods
