What problem am I going through?

[Furabixa]

Hello guys. I'm having a little problem playing through the emulator. I can keep 60 fps with 3x native resolution without problems, but from time to time the emulation suffers a great loss of fps for a second, as if the game crashes, then returns to normal for 60 fps. Do you know what kind of problem this is and if it is possible to solve it, or is it something inherent to the emulator and the shaders issue?

Thank you for your time.
