When I load the SMAC Version 4.0 patch, it causes gameplay to slow down. Loading the game used to be almost instantaneous; now it takes a lot longer. Using the terrain editor is a nightmare; it takes at least eight times as long to modify one single square, and sometimes I have to click four or five times on the same square to modify it. Also, the time in between turns, especially when there's terraforming going on, seems to be longer than it was before installling the patch. My drivers are up to date and no IRQ conflicts are present. SMAC is not a memory hog on the order of Doom; my 132 megs of main memory and 3.5 megs of video memory are more than enough. Tech support from Electronic Arts doesn't know what to do. Has anyone else had this problem? Help!
