Performance hit for mods

[Rauko]

Hi,

Regarding game performance, am I wrong on the following?

-Parts only mods hit game loading time but have almost no effect on fps once in the game.

-Mods that add functionality almost dont affect loading time, but hit greatly fps.

 

Bonus question not related to mods: a "many parts vessel" hits performance only when loaded, or also when it is on rails?

Basically yes.

Part mods with custom behavior will behave worse than purely patches, and plugins that do computationally expensive stuff during loading will affect the loading time. 

When a vessel is loaded is the only time there's physics simulation going on, so when it's on rails the game isn't worrying about it.
