My system is 32-bit Win XP PL SP 3, Intel Core2 Duo 3 GHz, 3 GB RAM, lower end NVIDIA graphics adapter with 2 GB RAM. I prefer to play Large maps. 3 GB on, Viewports enabled (40x30 or 40x40), 1280x1024, Low graphic settings. When I reach Classical era, the game starts to be unstable - more and more frequent random crashes, so in the early Renaissance they occur every a few turns. I guess my main problem is system RAM - and I cannot solve it without a BIG upgrade (new MB and processor, a lot of RAM, 64-bit OS etc.). I am about to play my current game until crashes make me to abandon it but I need some advice how to minimize memory requirements for the next games. Perhaps I would need to: - play smaller maps - maybe switch off some memory consuming options in BUG? - some people suggest to play earllier versions of C2C (I play v27) - any other advice? S.
