I have been using v1.09 patch with no issues. Today, I upgraded my memory to 1.23G of RAM (from 512) and then downloaded and installed v1.52. By the way, I am running the Direct2Drive version. Now when I try to run the game I get: FATAL_ERROR Your system has run out of video memory. Please try reducing your video settings. File:\main\civilization4.bak\SDKs\gamebryo2_0\core libs\NiDX9Renderer\NiDX9RenderedTextureData.cpp, Line:167 Followed by: Microsoft Visual C++ runtime library RUNTIME ERROR! Program:...Raxis games\sid Meier's civilization 4\civilization4.exe This application has requested the runtime to terminate in an unusual way. Please contact the support team for more information. I could sure use some help on this. So far I have tried the following: 1. Set memsaver to on in CivIV ini file, using the memsaver = 1 setting 2. Set memsaver to off in CivIV ini file, using the memsaver = 0 setting 3. Turn off Autosave in the CivIV ini file, using Autosave interval = 0 4. Set this item - Bink16Bit = 1 My system specs are: Compaq Presario R3000 Laptop Pentium 4 2.8GHz 1.23GB RAM ATI Mobility Radeon 9000/9100 IGP (Driver version 188.8.131.5236) Windows XP Home sp2 + updates I updated all my drivers and are the latest ones according to HP.
