Trying out the demo...
Well, it's better than it was at release (in fact, now that the map is properly oriented, it seems like a pretty fun game), but, seriously, it's not like it's tracing supplies in real time or something! A game that's a map with pieces on it shouldn't lag like crazy on a modern computer.
Is this because the engine doesn't support multi-core processors (i.e., it only uses a single core), or what?
EDIT: I tried lowering the security level from the setup file, but it doesn't help that much.
