I'm suffering from an almost guaranteed crash whenever I attempt to load planets in the lobby before a game starts, or when I choose to preview all in the system builder. This even occurs when I choose smaller systems. My drivers are the newest available as far as I know, and I'm on Windows 7 64-bit. My DxDiag is included.
Not according to your DxDiag: Operating System: Windows 7 Home Premium 32-bit ... Memory: 8192MB RAM Available OS Memory: 3550MB RAM The crashes you see are probably out of memory crashes. Either try to play small single planet systems or get a 64 bit windows.
