Crew FPS Tweaks (minor)
This mod works by disabling most of the thruster graphics the crew have when flying in space, which may significantly reduce lag when doing stuff like trading and gathering resources.
This is a version of my other mod Crew FPS Tweaks but instead of disabling all of the crew thruster effects, it disables all except one of them for less lag reduction but retaining the original graphics somewhat (it still has a decent lag reduction but not as impressive as the original mod).
