Gotcha. I had a hunch that was the case. In any event, I updated to 1.02 beta to try my luck. Seems to be going ok. Was getting really disappointing to get a few hours into the campaign, have some grand designs in the offing, and then have the game crash. Got a little hole in my heart each time it happened. Played a few turns last night and it seemed to be functioning nominally, although significantly more laggy than before.
I hadn't really noticed that yet, I was speaking more to the map scrolling getting bogged down in areas with numerous units. To be sure, this happened for me on the official patch, but things have slowed down even more now that I've updated to the beta. Probably just my hardware though, I guess.
