Kerbal Space Program

Thanks for the confirmation. Heres more information for consideration.

Subnautica vs Kerbal Space Program For memory issues (Both use Unity):

Subnautica:

Subnautica game saves are generally loaded once per game session into memory.

Kerbal Space Program:

KSP seems to be reloading the game in its entirety many many times into memory from the persistent file in one game session,
Heres a few times I think this is happening:

1. First time its loaded from the main menu
2. Everytime going from a loaded scene to the KSC screen
3. Everytime going from the KSC screen to the SPH/VAB
4. Everytime that a craft is launched from the SPH/VAB
5. Everytime that a craft is loaded from the tracking station
6. Everytime going from a loaded scene to the tracking station
7. Everytime going to the KSC Screen

Conclusion:

Subnautica loads the game save once
KSP loads the game save many times.

I 'simulated' Subnautica loading a game save continually for over an hour.
It does appear to have a memory leak if I do that, but a normal gamer would never do that in Subnautica

So yes...its a Unity Problem, sort of.

Suggestions:
Disclaimer: I have no idea of the state of KSP's code or if this is even possible

Load the persistent file once into memory and manipulate it there.
When launching a craft from the SPH/VAB insert it right into the existing universe which is in memory, no need to reload it.
Make the only times that the game is loaded is when the player loads a quick save.

This should reduce the memory leak considerably.
