Massive jet exhaust ring causing poor FPS

[The Optimist]

Stock game, no mods. I was launching my small, 30-part VTOL off the runway, powered by 6 Junos. This massive ring of exhaust particles appeared, making my game lag to about 20 fps. Then, when the VTOL lifted off, the fog ring mostly disappeared. Does anyone know how to stop this from happening?

Actually,yes.But i recommend you to use Module Manager,it'll make everything easier.
Just insert this patch in your GameData folder and the cloud will be gone.

@PART[miniJetEngine]:Final
{    
-MODULE[ModuleSurfaceFX]
 {
 }
}

edit:You can also out quite the module in part's *.cfg
