Strange gaming performance in Monster Hunter 3rd HD

[[Unknown]]

"Unbuffered" is a hack. It more correctly means "disable the game's ability to use buffers". I don't think anyone "should" ever use that option, unless they have no choice to get acceptable performance or somehow prefer the graphics without buffers (which may mean black screens or other glitches, depending on what the game tries to do with buffers that silently do not work.)

Temporary drops in fps can and does happen on some devices. It can be caused by background processes or the OS, but it can also be caused by things the emulator or game do that don't happen every frame. The faster the device is, the more stable it will be.
