After searching several ways to end the lag in the game, I discovered that if you put the volume of the music at 0 , will have a gain 5-10 fps.
I believe that this will serve for those who have a bad PC , or without video card (like me) .

You could also change the SPU settings. Config -> Audio -> plugin settings.

Try changing interpolation to linear or none. It might help without requiring you to go silent. You could also try Async Mix there.

I will try,but this trick is fine for me,i only don't listening the music,but the rest still ok
