The Advanced APB Launcher is a tool made by USPStyle and can be downloaded from the official link here. This is only available on PC, and will eventually be phased out once the options are integrated into the game itself. The launcher allows you to adjust texture sizes, render distances, and other graphical options.
This is the only launcher that’s temporarily approved at the moment, as Little Orbit will attempt to integrate these options into future iterations of the game. An announcement made on 8/27/19 stated that some players were using a disallowed launcher that allowed you to modify more than what they felt comfortable with. Little Orbit will proceed to unban these players based on the false advertisement and association as a supported launcher for APB.
