I had some pretty major lag times, but that was partially self-inflicted. I was very excited to get the save game over the weekend, and I moved my worker, printed a map, and started to analyze/plan what to do. However, on Monday night, my wife wanted me to see what that strange, burning smell coming from under her desk was. Funny, motherboards aren't supposed to give off smoke, are they? Anyway, that meant the Athlon 1700 was down, (at least until I got a new motherboard, which turned out to be friday), and I was stuck on my old 400Mhz. I did upgrade to 512k Ram, but even so, it was 4-5 minutes between turns, sometimes longer. So my QSC was played at 10-20 turns per night. Take a turn, read half a chapter in Inside the PC (or whatever else was handy), get a soda, check on the dog, tiem for another turn, repeat. It did make me very deliberate in my turns, there is nothing worse then moving a worker to the wrong tile, or forgetting to switch a micro-managed citizen back, and then having to wait FIVE MINUTES, staring at the screen, to switch him back.
That said, when Friday came and I had installed the new motherboard and video card, I was ready to go. (I told my wife that CIV would be the best test for speed and video quality on the new board, so I could play it before she got into Zoo Tycoon!).
Anyway, what a difference, lag times were about 15 seconds. I'll take that anyday. I usually spend that much time thinking about what I am going to do anyway. Awesome game, I love the special features, even if a couple of them did frustrate me. It is a challenge!
