System Specs
From Kerbal Space Program Wiki
General
Better hardware helps, but sometimes in non-obvious ways:
- A fast (per core) CPU. Dual-core may help, but given the limitations of the Unity engine, more will do very little.
- A dedicated graphics card (desktops & larger laptops)
KSP currently (1.0.2) does not make much use of multi core CPU's. You will get a better performance with a CPU with good single core performance and high clock speed. At some point the game also seems to hit a limit on whats possible so there's not much difference between 2 high-end CPUs running an extremely big space station.
The same is true of spacecraft design:
- Fewer parts, especially struts.
- Avoid highly detailed 3rd party parts.
- Keep installed part counts low.

Current Demo (0.18.3)
Minimum:
- Intel Core2Duo or equivalent.
- 2 GB of RAM (4 recommended).
- Intel HD3000 or better (Dedicated video card highly recommended).
- 1GB Free HD space

This is the absolute minimum to get a playable (if slow) game with smallish rockets, however. A faster system will greatly enhance one's experience.
