How much RAM should KSP be using?

[THX1138]

How much RAM should KSP be using? For me it varies between 2.5-3.5 GB but I saw someone complaining that it took 1.5 GB on their system so I wonder what's normal.

I think there's a new memory leak introduced in one of the hotfixes that is making for more RAM usage than before. Something to do with the new temp guages you see with F10.

It depends on if you are running stock or using a lot of mods. I run a fairly modded game and am around 1.7GB.

Using -force-opengl, I get about 1.2-1.7GB on stock. Right now I'm running "mostly" stock; stock parts, mods like KER, KAC etc for useful tools, sitting at 1.74GB while in the space center view.

It's possible that the two sets of figures are different totals.

I know that in Windows I can have one source showing something around either. There's the total RAM used while the program is running, which is in one Task Manager window. And then if you check the applications running, in another window, you see a much smaller figure for the particular program.

Since there are limits for the address space of a 32-bit Windows program, which those high figures break, I'm inclined to think they are the total RAM use while KSP is running. But they might not be from Windows users.

And the limit for your system, whatever the OS, is going to differ from mine.

They don't strike me as horrible numbers. I'm using a few Mods, and that could be why I have not seen anything like that with v1.0, but I'd expect things to run at that level. For a clean install. I'd think they were high.

I'm not sure what you mean but here's a screenshot. The only mod I have is Kerbal Alarm Clock.
