Hi everyone,

In order to check if CoD2 uses only one single core, launch CoD2. Go to task manager :
1. process tab
2. click on the button at the bottom left "Print process for all users" (or something like that)
3. click right on "CoD2MP_s.exe"
4. click on "Set affinity"
5. Check if only CPU 0 is checked.


If only CPU 0 is checked, it means that CoD2 use only one core. If CoD2 is still running, go back in your task manager and click on "Performance" tab, you will that your CPU 0 is overused :s

You can tick all CPUs if you want, but you'll have to it every time when you launch CoD2 :s

I don't know if somebody is interested by a solution, but now my CoD2 (even with CGAC) is running on my 8 cores. That's why I stream CoD2 without any lag

Kiss everyone!

Sorry to dissapoint you the game itself supports only 2 cores

@Monkkkkkkkk it's not...for anything decent you need 3-3,5

You can save affinity and priority with this small tool:

Just patch your cod2 manually, that's how I done it.

Yes, on my pc it always runs with 1 core only, i have a quad core, i5, and i always enable all 4.

Some year ago it somehow always started with all 4 cores enabled but it isnt anymore.

I created 2 .bat files (executable files) to run CGAC or CoD2 on eight cores (even if I know CoD2 will use 2 cores max).


set root="E:\Program Files (x86)\Call of Duty 2"
CD /D %root%
start "CoD2" /affinity 255 "CoD2MP_s.exe"

CGAC (if you launch CoD2 with CGAC, the game will use the parent's affinity (CGAC affinity)).
set root="E:\Program Files (x86)\CyberGamer"
CD /D %root%
start "CGAC" /affinity 255 "cgac.exe"

Put affinity 15 if you want to alloc 4 cores or affinity 3 for two cores.

Will check some stuff out, pretty sure this can be done programmatically via CGAC.
