Dual core processor and ctd

[PatternRec 1]

I read somewhere that CTDs can be avoided by making it so SC4 only uses one of the cores in a dual core processor. Can someone explain how to do that?

Add "-CPUCount:2" (without the quotes) to the end of the command line in the shortcut that you use to launch SC4.

Thanks.

Wouldn't CPUCount:2 instruct the game to use both? Shouldn't it be CPUCount1?

Another way is to start the game, Alt-Tab out to the desktop, bring up the Task Manager, go to the SimCity process, right-click on the process and specify which cpu to use.

Actually that doesn't give the count of CPU's but instead the CPU to be treated as primary (at least that is what affinity does, so I'm guessing so) The "title" is a bit misleading. To tell the program how many CPU's you have is actually a useless function. The numbering starts at 0 and goes to as many as you have. "Hyperthreading" is counted as added CPU's.

I did some experiments here. If you specify the number of CPUs as "1", execution is restricted to the first one. If you specify "2", execution shifts between the first two CPUs about once every 30 seconds, although other CPU activity can disrupt this pattern, as SC4 will try to get out of the way. I have a quad-core system with hyperthreading, so I set the number to "8"; this resulted in a fairly even and shifting distribution across the eight virtual cores. The main thing is that once you specify this option to the program, it takes control of when it switches CPUs, and it allows this to happen only at safe points. Hence, no crashes.

is this worth doing anyway if you have multi core, even if you have no issues with CTDs? or only to avoid them

I don't know if we have the quantitative data to say that.. it didn't make a difference as far as I can tell on my system. It may be almost as much superstition as results. If anyone has quantitative data, I'd love to see it. I doubt it can do much harm, soooo.......
