Has anyone else noticed that memory usage grows over time? I started a new game and the software was using 2.6 GB of memory. I re-started civ and did the same thing. Only 850 MB, one third as much. In a similar vein, the inter-turn lag seems to grow the longer you stay in the game. I noticed a huge difference after re-starting. Not sure if it's related to the lost memory. Oh. And the multi-processing claims are bullcrap. It is rather obvious from watching the Windows task manager and playing with processor affinity that this application is fundamentally single-threaded. It really is a b!tch to see my quad-core hyper-threading computer with 15% CPU usage.
