I did clear the cache. My game just froze after i changed turn..and Civ 4 goes "not responding"
I play standard map with 9 civs..barbarians on..revolutions off. Everyone has around 6 towns. Nothing so cumbersome for the system. It's classical era. I haven't made any changes to the game whatsoever.
My specs are as follows:
Ram 4gb
Win 7 64 bit
Intel E7400 Core Duo 2.8ghz
GeForce 9500 GT 1 gb
did u attempt the savegame
You know what, I used to have that same GeForce 9500 GT 1 GB and it caused crashes in both C2C and RoM-AND no matter how small of a map I would pick. I tried a million things, some of them pretty obscure from searching through various threads, to try to get it fixed but it caused crashes no matter what I did.
Now my setup is different than yours as I was using XP with the 3GB switch (tried many differenta userva settings), but I ended up replacing my graphics card (actually to an ATI Radion graphics card with lower memory but higher performance specs overall) and it IMMEDIATELY solved all my problems, I picked up the card used on ebay for like $60 bucks or so. Now I can run it with Giant maps and 25 civs no problem. Seriously.
Didn't read through your whole thread on what your specific issue was but quickly noticed the graphic card you were using and since I had several weeks of messing around with that card before finally figuring out it had an issue. My thinking at the time was how it allocated virtual memory in XP's 4GB virtual memory space, that it somehow was interfering with the 3GB I was dedicating to the game.
Whatever the reason, I would consider looking at another video card...
