Whats stuff would make kerbal space program run smoothly on pc and in the future game

Turn the graphic settings down, that should help...

Okay thanks easy answer!

From my experience, the more mods you have and the more complex the ships, the slower the game runs. The first part is probably because KSP loads at least some information about every part into memory, and the second is because physics calculations have to occur on every part that's within a certain distance of the active ship.

If you have money to spend, consider upgrading your computer - the easiest way would probably be making sure you have the maximum amount of memory your motherboard and OS can handle, since KSP seems to leak memory a bit.

I'm currently trying to build a SSTO spaceplane. My main limitation at the moment is getting the thing off the ground because it lags like crazy. I've found rearranging parts even slightly can have a huge difference on frame rate. I've a feeling some self-intersections are the cause, or maybe wheel-ground "collisions". Graphics settings had absolutely no effect on performance for me.

Perhaps not what the OP was getting at but i wonder - what limits KSP the most hardware wise? GPU, CPU or RAM? It does seem to use a bit of RAM, but if i'm not running anything else it's rarely at 100% of 2GB. I'd have thought the CPU would have helped with the physics calculations, and reducing that pause you get when you go to start a flight. But when i watch videos from people with much better hardware than me it doesn't look that much better (E2140 @ 2.6). And i wouldn't have thought the graphics would be that taxing...
