Simply saying "the effect details are too high" or "there are too many effects" is not nearly enough information to diagnose the problem you may or may not be having.
In game: What system were you in when you experienced a FPS drop? Were you inside a nebula or asteroid field, or close to a particular base? What ship were you flying? What other ships were nearby; were they shooting; and if yes, with what weapons?
Your computer: Is your graphics driver up to date? Were you playing full-screen or windowed, and were you playing at your native resolution? Were you running any programs in the background?
We require adequate responses to these questions if we are to help improve your gameplay experience.
