I started a space dock for assembly of modular interplanetary craft which has caused my first experience with severe framerate issues. For reference this is the Space Dock with a small RCS tug with a large Interplanetary Craft and lander on the right. I run an i5 2500K chip, 8 gb RAM, 560ti graphics card. Trying to bring the interplanetary craft into the space dock sent my computer into a crawl. I had hoped to use the space dock to store several modular components plus many more fuel tanks. At this point I'm going back to the drawing board to reduce part counts and simplify. Any advice on KSP settings to improve performance? Anti-aliasing on/off, v-sync, physics calcs, etc. Also with my system should that many parts be slowing KSP down that much? Thanks, HAM
