A BGMI config file is a modified version of the game's internal settings files, such as Active.sav or UserCustom.ini . These files are used to bypass the graphical limits set by the game based on your device's hardware, attempting to force "Smooth" graphics with an "Extreme" (60 FPS) frame rate. Risks of Using Config Files
: Forcing high frame rates on unsupported hardware can cause severe overheating, which may lead to permanent processor damage or battery degradation.
