Block animations (and the lighting changes they cause) cause a great deal of FPS lag. It would help reduce FPS lag if there were an option to disable animations. This would allow lower-end computers to run star-made properly, and would be especially helpful with preventing lag when building/around large ships. As an example of the horrible FPS lag caused by animations, a large ship I'm building drops me from ~80 FPS to ~4 FPS apparently due to animations.
