This guide will let you know how to use SetEdit in BlueStacks Emulator.
First, you will need to open up your BlueStacks Emulator, go to Playstore, and search for SetEdit. After that, tap on the Install button.
Once the installation completes, open it up and click Add New Settings. Input the peak_refresh_rate command and input 240.0 as a value. It will increase the peak refresh rate.
The next command to enter is peak_refresh_rate, then enter the same value again. You need to input the last command, custom_game_access_freefire_fps, and enter 240.0 as a value.
Now close BlueStacks Emulator and then restart it. Launch Freefire and you will find a change in FPS.
