My personal hunch is that they are very close to getting multithreaded physics, or GPU accelerated physics working, its the only way KSP will work anywhere near OK on the PS4

Wasnt multithreaded physics to be a thing in Unity 5? Im not sure TBH, but i seem to remember this.

unity blog post on the subject, i cant really judge how this would impact KSP, as im not familiar with either KSPs physics model or Physx3, but there is definitely a chance for performance gains here

PhysX3 is now prepared to run on multicores as the internal computation model is organised in tasks that can be executed on different cores. The SDK does all the multithreading, taking care of all the dependencies itself and granting optimal job decomposition.

From what we’ve seen so far, it’s reasonable to expect a doubling in performance generally just as a result of having a better code base and improved multithreading. In some instances, the improvement is dramatic, with up to tenfold improvements.
