Hello, i've this problems with the Alpha X (my first contact with this superb game): The bug occurs only after a few minutes to half an hour to game time: the game will not run smooth. Scrolling and animations are stopped and started again in intervals. Either two or three stops in a second (the whole time since it begins), or sometimes two seconds of playing time and a half-second "break" which decreses to about one second playing and half second break. Sometimes the whole game becomes faster! All units are moving/collection two/three times faster. After restarting the game, it starts up again after a certain time. The game begins here to be unplayable :/ CPU usage drops significantly from these breaks. In Task Manager, you can see a clear zig-zag of about 5 to 50% of one of the cores. My PC: AMD A6-3670K (4x2,8 Ghz) with 8 GB RAM. Windows Vista 64 Bit.
