Have you guys seen the tech support thread for speeding up the game on multiple core processors?  I've got to try that.  My laptop is a dual core.  [:)]

Not sure what I'm doing wrong here. It doesn't seem any faster to me [:(]

With HyperThreading and Dual Core CPUs being common in all kinds of systems there may be alot of people interested in controlling which processes use which CPU. This would work for Dual CPU systems to.

The program to use for this is Imagecfg.exe. You can google it to find a download, or get it off of a Windows 2000 or Windows XP Server Resource Kit.

Imagecfg.exe will work with Windows XP(32 bit and 64 bit), Windows 2000, Windows 2003, and hopefully Windows Vista. It is a permanent change to the file, so make a backup before testing.

Imagecfg.exe has a bunch of uses, use the "/?" switch to see all of your choices.

To set a process's affinity use "imagecfg -a 0xn [File Path] [File Name]

Replace n with the CPU you want the process to use.

1 = CPU0
2 = CPU1
4 = CPU2
8 = CPU3

So if you wanted to set C:\Test\Dummy.exe to use the second CPU(CPU1) ir would look like this:

imagecfg -a 0x2 C:\Test\Dummy.exe

For dual core or dual CPU users both CPUs will perform equally, but with HyperThreading enabled systems the first CPU (CPU0) is faster, because the 2nd CPU is just a virtual CPU recycling unused cycles from the first CPU.

By moving processes around it can allow you maximize the performance of CPU intensive programs and games by assigning all necessary processes to 1 CPU, freeing the other CPU for the intensive application.

I've just started messing around with this so I don't have any benchmarks or proof that this does anything, theoretically it should help, most likely in a very small ammount though.

Flaws:
Imagecfg does not seem to recognize folders with spaces in it like "C:\Program Files". To get by this copy the Imagecfg.exe file to that directory and exclude the directory /path.
