Doesn't this game support up to 4 GB of RAM?

Hey everyone,

So I just realized something. I know that KSP is a 32-bit game, which means that it supports and can use up to and not over 4 gigabytes of RAM. However, on my machine, it isn't even using two. I always have CoreTemp running in the background, and it says that my RAM usage only goes up by just over a gigabyte, far short of the maximum of 4. Is there a way to make the game use up more of my RAM, and therefore run faster/smoother/whatever might happen? I have 6 GB in my machine, and most of it just sits idle while the game runs.

The game only uses the RAM it needs. Performance issues are caused by the physics calculations, which is a function of your processor. You only ever need to worry about the RAM limit when you are loading lots of parts and textures. If you have a very low mod load, RAM usage is small.

I see. Good thing my processor is soon to be updated! Thank you.

KSP currently cannot mutli-thread the physics, which is partly a Unity limitation. I suggest getting one that has very high clock speed PER core, NOT combined. I believe you can roughly estimate this by dividing clock speed by the number of threads (take into account processors that run multiple threads per core like an i7) you have.

if you run the game w/o mod, it takes ~1gb only
