One concern I have about KSP

[Magnet_man16]

I once thought the same thing back in .18 but just last update my game is totally lag free. So yes the lag gets really bad but then thy do a hoover up and clean their code. I do that, takes a while to go over everything line by line though. But yea I went from 20/30 FPS to about 60FPS currently. Now I hope building a space station will be possible.

I do not share op's concern about Squad not being able to optimize ksp further.

I would upgrade to a quad socket, 12 core xeon with 512 GB of memory and 4 top of the line GPU's in SLI if that's what it took to run Kerbal. I love my little green men that much!
