I have been trying to play Regions and Provinces Bigmap v2.4 with little success. I have also tried Stainless Steel 4.1 of which has done very well.
Now the crux of the problem. I have played both of them with the same graphics card on the same settings and the same game video settings.
I wiped out 64 regions in SS and no slowdown in the system.
In RPMBM, when I conquered 52 or 53 regions, some of the graphics get corrupted. The campaign map does not but the buttons for the various messages that drop down the left side of the screen get corrupted. In fact it will get so bad the mouse-over underlay gets corrupted and the buttons become useless.
With this info and both mods have added factions, I believe the problem may lie in the RPMBM mod itself. The stratpage(x).tga and sharedpage(x).tga in RPMBM are .sd convertor pre vM2TW v1.2. The stratpage(x).tga and sharedpage(x).tga are like Tornnight's thread in his mod section and it works.
Could this be the problem we are having trying to make the RPMBM mod to work?
