Nope ... but
The MemSaver Option is inside
C:\Documents and Settings\New User\My Documents\My Games\Sid Meier's Civilization 4\Civilization.ini
It was introduced with Patch V1.52. Open the ini file and try reversing the setting (if its 0, make it a 1 if its 1 make it a 0) thats a non-fatal change, if it makes things worse, go back to where you were
(0 is a number in the above not the letter O)
Be interested to hear the end result - not heard this issue before
