I have a dual core computer and would like to now how I would set DF to use one core and use the other core for everything else.
I run Vista, Intel Core Two Duo CPU P8600 @ 2.4 GHz.

open the task manager and in the process list right click dwarf fortress and set affinity to one core, and then do the same to all the other processes and set their affinity to the other core.

It's not worth it though, you wont' gain any* performance.
*theoretically you could gain a few nanoseconds of execution time, or around 0.000001%

Officially, forcing affinity is for restricting the number of simultaneous threads misbehaving applications get. e.g. an old app may use multiple threads to have several processes "in flight" at any one time, but uses resources that aren't multi-thread-safe, so crashes when its threads are actually run in parallel instead of time-sliced.

Thanks for the fast replies.

The d# branch, which is currently being merged, is even somewhat multithreaded. It'll reduce performance in the not-too-distant future.
