I came here to write yet another post complaining about this. Actually, I registered for the forum and wrote the post, and I'm still waiting for the shapeforms to finish deliberating. I'm playing the first campaign mission. And there's only one surviving computer player. And it's STILL taking forever. I'm running a Lenovo w520, Core i7 2820 processor, 16GB of RAM. My machine is basically bored silly (I checked Resource Monitor just to be sure), and it's still taking 3 minutes to get a turn done.
I decided to do something else while it deliberates, so I switched to running the game in a window (ie, not fullscreen). Then I noticed that when the window has focus it maxes out one of my cores, but when it's not focused it only uses a few percent of the CPU. So basically I can't do anything else - I have to watch the motionless "progress" bar. Gah!
I'm sure it's a great game, it was recommended by a friend, but this is just ridiculous.
