Just a reminder that when you pick a config and download one, you will probably want to change a few things in config/ClientPrefs.cs:
$pref::VideoFullScreen = "TRUE"; (True if using fullscreen)
$pref::VideoFullScreenDriver = "OpenGL"; (OpenGL Required)
$pref::VideoFullScreenRes = "1920x1080"; (Your monitor resolution)
$pref::waitforvsync = "false"; (Make sure this is false)
$pref::PlayerFov = "120"; (Pick any FOV between 90-120)
If you are having issues connecting to the master server on any of these configs, open the game, go to options, find the network tab, click add and use this address: t1m1.pu.net:28000
If you have any other issues with anything, join the discord and post any questions in the #config-engineers channel.
