This can improve latency, fix audio crackling and maximize overall performance. The performance profile is only held while plugged in: it is released when the charger is pulled and held again when it is plugged back in.\nNo extra software is needed beyond what desktop distributions ship. The hold is released when Game Mode is turned off or RetroArch exits, including after a crash."
