RAM consumption is high at loading

[Kerbal the crazyest]

Sorry for posting again (I'm having some trouble *again*) When I start the game, it's ram consumption is about 1.2 GB ram, but when it's ending the loading, it takes 4,1 GB of ram, which is a high amount, having in mind that this pc has 8gb. It means, that in that moment, the game is taking more than the half of the memory. But, after 30 minutes playing, it reduces to 2 gb and I can run KSP, Discord and Spotify at the same time and without lag. My question is, why the RAM consumption is that high on loading but in launches it's lower?

Maybe there is a mod with a huge memory leak........ or maybe I have a mod I don't need

When the game is loading, it loads everything into memory; once the game is running it doesn’t need everything in memory any more and can free it up again.

Parts with detailed textures, especially internal spaces, will increase the memory use even more during loading.
