Still having issues after driver update.
The text of the error is as follows:
"Failed to allocate video memory. Please try reducing your graphics settings.
File:\main\Civilization4\SDKs\Gamebryo2_0\CoreLibs\NiDX9Renderer\NiDX9SourceTextureData.cpp, Line:321"
This then causes a Visual C++ runtime error due to abnormal termination.
I would try reducing my graphics, if they hadn't been at their current settings for years without previous problems. It seems likely (to me, at least) that some sort of graphics bug has been introduced either in 1.0 or in patch a. However, if no one else is having problems like this, I'll have to assume the problem is with my system.
Either way, if some other people with XP could test for this, I would greatly appreciate it.
I'm getting the above error (exactly) after playing for a while and then trying to access the tech-tree or civilopedia, etc.
Also, I get the Memory Allocation Error whenever I try to load or start a new game after playing beyond the first turn of a game. It also comes up on the 3rd, and a couple times 4th, time after trying to start a new game (on map generation)(after exiting to menu before founding a city on the prior map). I've only had it happen once in the midst of a game (but that might be due to the above error killing my game before it has a chance to).
