The game emulates quite well, however the sound of the music and dielogue is extremly choppy. Any way to configure it, to fix the sound?

Switch from Dual SPU to Synchronous in sound settings if the audio is choppy.

Also, some other things to change:

• Use the Dynamic Recompiler (JIT) CPU emulation engine.
• Disable Advanced Bus-Level Timing.
• Try switching the 3D renderer between OpenGL and SoftRasterizer. One 3D renderer may work faster than the other, depending on the situation.
• (Mac only) If you are using a pixel scaler and your machine has an older GPU or an integrated GPU, it might help to run the pixel scaler on the CPU by disabling "Run filters on GPU if possible". However, if you are using a newer GPU, then enabling "Run filters on GPU if possible" will remove any performance penalties related to using any video filters.
• (Mac only) Do not enable any source filters if you are running a pixel scaler on the CPU. This combination results in a substantial performance hit.
• (Linux only) Do not scale the display window beyond 1x, as this can result in a substantial performance hit.
• Disable Advanced SPU Logic, and use the Dual SPU Sync/Async synchronization method.

Thank you.
