Performance Tweaks

The "CPU Clock Multiplier" option in the RetroArch options menu is fairly important when it comes to performance. Setting it too low might cause your game to run slower than intended, but setting it too high can cause stuttering and slow performance. It is recommended to use somewhere between a 4x and 8x multiplier.
