Where are the settings and what's in each tab?
Settings open from the lobby and also during a match, from the pause menu. Changes apply immediately — no restart needed.
Favourites — settings you add yourself with the star icon.
Basic — language, server region, and what's shown on screen in game.
Controls & HUD — button layout and size, joystick, combat helpers, firing modes, item-moving options.
Sensitivity — camera sensitivity per sight type, and all gyroscope settings.
Graphics — quality, resolution, draw distance, field of view, post-processing, shadows.
Audio — volume, ambient sounds, headset microphone routing, visualization of sound effects.
Notifications — notifications on/off, all at once or by group.
System — account linking, nickname, tutorial, deleting account and maps, microphone access, restoring purchases.
What isn't available during a match
The in-match settings screen has seven tabs — there's no System tab — and three more things are lobby-only:
Language and Region for servers (the Main section of the Basic tab)
Control Buttons → Edit (the button layout editor)
Re-adjust Graphics
Everything else — including all sensitivity, graphics, audio and notification settings — can be changed without leaving the server.
