So the game menu loads and runs fine. I'm using my laptop so to be sure I have all graphics settings at their lowest. However as soon as I start a game, the main planet seems to load partially, and then the game crashes. I tried running the system monitor and it seems the game isn't using all the available RAM that I have (8 gigs), it tops off at 4 gigs. Is there any way to fix this?
Are you by any chance using a 32-bit operating system? (or running the 32-bit binary instead of the 64-bit one?)
The game should not use anywhere near 8 gigs unless you are loading a massive system. try updating your graphics card drivers. fixes 90% of all problems.
