Sudden performance issues

[Haukifile]

KSP ver. 1.0.5.1028 32-bit

Windows 10 64-bit

Issue: Up until a few days ago, KSP seemed to be running fine on my laptop. Now when I access my flights in my career save, my framerate slows down into 10 fps territory, even on the map screen. I tried doing a clean install, but it didn't help at all.

Mods I've installed are:

Kerbal Engineer

Chatterer

Precise node

Waypoint Manager

Any ideas? It's in no way a high performance pc, but did run the game ok until the last few days. I have a gaming pc on which the game runs great, but I like playing the game on the laptop. :/ Can the amount of ongoing flights result in these kinds of problems? I have a few empty crafts orbiting Kerbin and its moons that I could bring down, but haven't yet got to them.

Well, I have found the culprit. I had the Snacks life support mod installed before the performance issues, and the issues went away after reinstalling the mod. So it seems that my save, which was played with Snacks until then, did not play well at all after suddenly removing the mod.
