Loss of FPS when KSP is unfocussed

[endernite54]

Hello ! A strange problem appeared two weeks ago, no significant change to the game were made and reinstalling it didn't fix the issue !
I play KSP in full screen mode, and when I unfocus KSP (opening my browser, alt-tabbing etc..) the game starts to lag tremendously, I get like 3 FPS... Which is really inconvenient as you may imagine !

I have Kerbal Engineer, SSTU, persistent rotation, probes plus, decals, Direct launch vehicles and Space shuttle payloads.. Running ksp in vanilla doesn't fix the problem, I've checked the logs, no errors when the lag occurs...
 

Good day,

-Luca

I know there used to be, and there might still be a setting for KSP running in the background. Turning that off might help if you don't need the game running while you're multitasking. 

P.S. That setting might only be referring to when you "pause" the game. I can't remember.

The setting is called "Simulate in Background" I believe; it is in the graphics section
