Horrible lag!

I just bought this game, and I seem to be having trouble with it lagging. A lot. It will play fine for the first ten minutes or so, but then it will suddenly start lagging like crazy. If I alt-tab out of the game window and come back to it a few minutes later, the game will run fine for about five minutes before starting to lag again.

Is there any way to get this game working correctly? My laptop definitely meets all of the game's system requirements, so I'm not entirely sure what the problem is.

It's sort of making the game unplayable and unenjoyable.

(I'm not even sure if this is the right place to post this. I can't find any forum Anarchy Enterprises' website...)

Did you ever get a solution to this problem ? I just purchased this game and am experiencing the same lag.

Thanks, I just love coffee and I was thinking about getting this.
