Going through a month would be an exercise in frustration, seeing as every other second the game comes to a halt. The game is impractical to play with performance so bad.
So yes, it happens on my Windows laptop, but not on my iMac. Interesting. Mind you my iMac is topend and my laptop isn't.That tells me what I need to know then - it's not the game, it's something peculiar to your machine, as I don't get any such issue in my iMac. Quite what, I can't imagine. I'll try to remember to test your game in my Windows laptop, when I get back to it tomorrow.
