Getting More From Multiple Core CPUs

[wlape3]

Here is something to try. Next time you play, start breakthrough and then start up the task manager. Then click on the "Processes" tab, click on the button on the lower left labelled "Show processes from all users" (this elevates task manager to Admin status) and then right click on the process called "SC-WWI Breakthrough.exe". Click on "Set Affinity" and assign it to one of your idle processors. This will allow the program to execute faster since it should be the only task running on that CPU.

You can use this program:

to set the affinity for the game engine permanently. You can also go into your bios and set which CPUs your OS will use by default. Set up all but one for the OS and you should then be able make the deselected one your gaming CPU by setting the affinity for your game executables to this CPU.

And this really works?

Honestly?

Yes. I tried it this morning and the game engine certainly feels faster but I haven't timed it yet.

I measured the execution time of the same turn with the processor affinity set to a specific CPU and when it was not assigned to a specific CPU. The times were faster when the affinity was set but not enough to say it really made a difference. Total time running normally was about 5 minutes. Running with a specific affinity was about 20 seconds less. Only a 5-7% improvement which could be explained by the differences in random events and AI actions between each execution sequence.

Oh well. YMMV...
