Multicore support for XP

How well does Win XP SP2 support multicore cpu's?
I'm currently using an AMD Opty 175.

I installed the AMD multi core driver and I believe all it did was add the ability to choose program affinity and select core 1, core 2, or core 1 + 2

Playing EQ2, cothe 1st core goes to 100%.
If I change the affinity to the 2nd core then that one goes to 100%.
The core not set just spikes from 0-8%. (using AMD Power Monitor to see cpu utilization)
If most of windows is not load sharing across the dual cores, would it be better to change my games to the 2nd core and leave windows using mostly the 1st core?

Or does WinXP load share?
 
It will, but you just don't have any thing else running to use it. The affinity simply means which core to favor. Commonly this is used to help applications that have problems with SMP work properly. If you start up another CPU intensive app that will probably run on the other core.
 
Your cpu has 2 cores.
Using the affinity patch, you can in taskmaster tell a process/program which cores to use.

If most of winXP and other programs use core 1, would there be a benefit to games to tell them to use core 2 which site mostly idle.

A game written to use multiple cores would split up into many processes that would load share across the cores. Most games do not do this yet.

Unless WinXP has a program handling this function.
