What's that annoying split second freeze that happens every so often?

[Bug_]

I'm sure everyone's noticed that annoying split second hiccup when you are flying a spaceship. Even though I have a computer with pretty high specs (i7-4790k overclocked at 4.4GHz, GTX980 graphics card), it persists. Anyone know what is causing it/ how to get rid of it?

It's a Unity3D engine bug, as Steve_V mentions here, and has been known in Unity for a long time, the Squad devs know about it but can't fix it.

It does not affect all players though, so anything that affects Unity's garbage collection should be avoided, make sure your anti-virus is not scanning KSP, defrag your drive, turn off unneeded background processes, don't run fraps/bandicam, don't use Hamachi and even try allowing KSP through your firewall, as Unity uses urls to find game assets even on your own system and stupidly checks network adapters first.
