Higher performance is due to setting Vblank in advanced settings to 240 (bypasses forced synchronization in the game), and disabling Zcull by editing settings in the emulator (not recommended for other games, but works well for MGS4).
At the moment, there are places in the game where the engine intentionally lowers the frame rate to 24 fps after which the emulator crashes with an error.
The developers hope that they can solve these problems in the near future.
