Does this make sense?

I was playing KSP one day. I decided to fly a 600-Part Monster that I downloaded a few weeks ago. I only have 3GB of RAM but it still flew without killling my laptop.

It was at about 0.5 FPS, but it didn't crash the laptop! Does this make sense? If it helps I'm running Windows 7 Home Premium, with an Intel Celeron CPU and a 64-bit operating system.

Thanks!

yes, the unity engine is that way

Thought it would be different if you have 32-bit. There's a unity bug, and if it pasts the "RAM-wall", it will crash.

Thanks! Also the RAM-Wall thing could be important...

Yes, it makes sense - Windows doesn't normally crash when you run out of memory, because of something called the page file (or swap file). I won't bore you with the details, but it works like this: When Windows runs out of memory, it starts using the hard drive as memory.

However, when that happens things slow down a lot because using the hard drive as memory is really slow.
