Inconsistent initial load

[ASW122]

Hi All,

I've been getting some slightly odd behaviour when I open KSP.

I'm running a pretty heavily modded install, but resources aren't an issue (32GB DDR4 2400Mhz RAM, 8-core hyperthreaded i7-5960X (3Ghz, no overclock), 2x 2GB NVIDIA GEFORCE GTX 760 Graphics Cards).

Like I say, my install is pretty heavily modded, but I don't think that's the root because its inconsistent.

Basically, when I open, usually it opens the whole program to the main menu in about 90 seconds - 2 minutes. But occasionally I'll open it and it will barely have loaded anything after 20 minutes. I leave it a couple of hours, re-load and I'm in, in the usual 2 minutes. No changes made, just walking away from the machine or opening a different game for a few hours.

Anyone got any ideas about what might be causing it?

Thanks
