The reaction time in Free Fire is entirely dependent on the sensitivity settings. It is, therefore, essential to figure out which sensitivity settings suit your playstyle. Copying someone else’s settings can land you in big trouble.
Adjust your sensitivity settings according to your device. On low-end devices with 2 GB of RAM, keep the sensitivity at the maximum, otherwise play at default sensitivity.
