1) Do you have the Allow AI to use extra CPU cycles option turn on? This does exactly what it says and on a non dual core machine it will slow the game especially with all the AIs you've got in game.
Right! That's one thing I hadn't considered. No wonder it was maxing out my CPU, I told it to! I guess I'll be turning that off until I get myself a dual core.
2) GPU Throttle. On or off? This had more to do with crashing due to overheating the vid card then anything else but it can be an issue for performance too I think.
Are you talking about the Throttle Framerate check box? I'm not exactly sure what that's supposed to do. Though I noticed if it was off, my ship models in the shipyard looked to be skipping frames every cycle, so I've left it turned on. The animation is alot smoother that way.
3) Norton. Ok this has been mentioned but I felt it needed to be repeated. Norton kills performance. Period. No discussion. No ifs, ands, or buts.
Yes I knew that, but I'm usually too lazy to turn it off. For most of the games I play, it's not much of an issue.
I never understood the need to have antivirus software running constantly.
I'm paranoid? I guess maybe I should just get into the habit of turning it on only when I'm online and browsing. It has caught a few bugs for me over the years, though I have to admit it's usefulness is limited. The few that it did catch, it couldn't do anything about them. I had to manually go into where the file was and just delete it. But at least it told me were it was.
You should have roughly 4x your available RAM as free HD space.
That seems rather excessive to me. I've read a number of times before that it should be 2:1. Which is what I have now, with the max set at around 4, minimum at about 2. And like I mentioned, when I checked, with the game minimized, only 1.6 of the page file was being used. So I don't think that's really an issue.
5) XP or Vista? Vista right now isn't exactly the most game friendly OS. This will change but for right now avoid it. XP isn't exactly the best either but if you know what to shut off it can be efficient.
XP Home. I don't plan on getting Vista until the programs I get start forcing me to. Aside from DirectX 10 I see no benefit in it, and no one's really using that yet.
