Since I have been having problems with this game about the same place as others,I have done some research donig some old fashioned process of elimination.
My machine came loaded with Vista. If you want more speed, get into the thing and set it for performance not beauty. It also came with an onboard video that will not play bigmap after about 30= regions. This includes updating the motherboard BIOS and maxing the video settings on it, and updating the video chipset.
I checked the size of the map.rwm fo which RTW and M2TW both use and here are their sizes:
RTW Vanilla map.rwm=3247
RTW Terrae Expugnandae of which uses the Mundus Magnus map map.rwm=7215
M2TW Vanilla map.rwm=4350
M2TW RPMBM 2.4 map.rwm=13736
I also played one turn of RPMBM and and the system.log.txt with the "* trace" switch used, had over 144,000 lines and that's only campaign map with all battles auto-resolve.
I conclude many of the unresolved ctds are underpowered video systems. If someone that has had unresolved ctds with this mod and not on another mod with 180+ regions and comparable map.rwm size, please refute my conclusions with facts including mod name, size, etc.
