I have been playing GC3 a lot and probably the main issue I have run into is that on immense maps around turn 200 I start getting a lot of interface freezing.
Recently, I made a strategic decision to stay with my dell studio xps 8100 for 1-2 more years while upgrading 2-3 components. I figure $200 or so is a lot better than $2000 or so for a new rig with SSD and etc.
1. First thing I tried was going from 8 -> 16 gb memory. This made the game a lot smoother, but did not seem to have any effect on freezing.
2. Next, I went for an upgraded video card. I had notice that the Radeon HD 5770 tended to develop a lot of fan noise while playing Civ 5 though not GC3. But I figured a card with twice the memory etc. must be an improvement even though it is not state of the art, so I got a GE force GTX 750 Ti 2 gb fairly cheaply. Since it calls for 300w, I decided another good move would be to swap power supplies and went from the standard 350w to a 500w Corsair CX, and give myself some elbow room. And if I want to plug something else in I wouldn't have a power issue.
At the same time (see my post http://forums.galciv3.com/462459/page/1/ for details) I started running HDMonitor on a second monitor while playing GC3.
(First let me mention that with this configuration Civ 5 no longer causes the fan to go noisy.)
Here's the issue, which I don't even know if it is an issue. HDMonitor reports the temperature of the CPU cores and the GPU. GPU temps were fine. CPU cores, however, are running very close to spec. My XPS calls for a max temp of 72.5 C for the CPU, and I have been hitting high 60s and from time to time low 70s.
Questions for gurus, developers or anyone:
1. Is running this close to spec temperature a potential problem? I have played a new game of GC3 to turn 140 with no issues but the real crunch will be in about 60 plus more turns. I will report on progress.
Please note: Civ 5 BNW, on a large map, is also a very graphics intensive game. But I noticed that it runs no where near as hot a CPU and the CPU usage was about 50% of that for GC3 (as monitored with task manager-> performance).
Big Question: when the devs talk about optimizing, is CPU load part of the plan? The talk all seems to be about memory size.
2. I have had a real problem finding an updated CPU cooling system for the studio xps 8100, so I don't know what to do about that --- seems that Dell isn't very friendly toward third parties on the MoBo. I could try just adding a case fan, but I am not too sure how to go about that.
3. I wonder if people who are having problems with crashes and such should try using HDMonitor (or others). If you are running hot, sometimes just cleaning out the fans helps a ton. (BTW, my case is clean as a whistle at the moment, lol).
