I decided to go and get addicted again to Civ IV after a long break. I upgraded from version 1.0 (no patches) to latest version 1.74 from the game itself. I also upgraded all of my drivers with the help of Driver Detective. DirectX component(s) were upgraded from MS download pages.
How ever, the game seems to crash very often and in the late game, it is totally unplayable. Unfortunately I cannot compare to version 1.0 because I played only few rounds from the beginning. Currently I am trying single player game with huge land and epic speed. I have tried different graphical settings, but the game just keeps crashing. In early game, crashes seem to occur with 5-10 minute periods. Now around 1400AC, the game is totally unplayable. I cannot make a single turn without crash.
The game will crash in most cases when I move the map, when City builds something after the turn or randomly when some unit gets its turn and gets focused.
The crashes are in most cases total crashes so that the game just vanishes. Sometimes crash is caused from runtime error with "R6025 pure virtual function call" text from Civilization4.exe.
Any help or hints what to do?
Thanks in advance.
