This is the most serious consequence. Krafton has a strict zero-tolerance policy against any third-party programs that modify the game's client files. Using a config file to unlock FPS or alter graphics falls under their definition of making "illegal changes to client file data". The game’s anti-cheat system actively scans for these unauthorized changes. If detected, your account can receive a 10-year permanent ban . These bans are rarely, if ever, overturned.
By default, the game detects a phone's processor and RAM, locking the settings to prevent the device from overheating or crashing. For example, a budget smartphone might be restricted to "Smooth" graphics at "Medium" frame rates. A config file modification involves replacing or altering these default instruction files to trick the game engine into thinking the device is capable of handling higher loads, thereby unlocking options like "Extreme" FPS or "HDR" graphics on unsupported hardware. bgmi smooth extreme config file download link
By default, low-end devices restrict graphic settings to "Smooth-Medium" or "Smooth-High" (20 to 30 FPS). Placing a custom config file into the game's core directory forces the engine to run at the "Extreme" frame rate preset, unlocking 60 FPS or even 90 FPS on supported displays.
