I'm sure this wasn't an issue on vista, but anyway, any ideas what i'm doing wrong?

I've got a q6600 so want the game to use all 4 cores obviously.

See here: http://www.techenclave.com/guides-and-tutorials/cpu-affinity-made-easy-67317.html

So I put:
C:\Windows\System32\cmd.exe /C start /AFFINITY F "C:\Program Files (x86)\Activision\Call of Duty 2\cod2mp_s.exe"

yes? but it doesn't work, any ideas??:(

if you having that as a problem its a PC problem and not a game that game runs great on a single core.

but if I set the game to use all 4 cores it runs silky smooth, but this is an annoyance going into taskmgr every time i launch the game.

the game is too old to be quad threaded it can't run on 4 cores simultaneously.

You can do it manually though, via taskmgr:confused:

yeah but the game doesn't have 4 threads so it won't use all the cores simultaneously, just setting it to use all cores wont magically rewrite the entire game code.

Most modern games can't even use 4 threads.

I wasn't suggesting it did, but there is definitely an issue with it only running on 1 core - so really, I just need to make taskmgr remember the affinity setting for this one process?
 
but the game can't use all 4 cores, and task manager will set it's affinity to all 4 cores by default, but if it's a single threaded game (which suspect it is) it will only use 1 as it physically only can use 1.
 
Going into taskmgr and setting cod2mp.exe to use all 4 cores makes it run silky smooth.

This is fine, but it's a bit annoying having to do it every time. The URL I have posted in the OP is the workaround for this, can you help me set it up?

I've followed the instructions and it still won't work.

Then I have no idea how you'd do it I know there was another game you had to alt tab out of to get it to use more than one core can't remember what it was though.

lol u used to set it to run on one core not all four :D

open task manager do it that way.

This is a separate issue. What you're talking about was fixed in an early cod2 patch, where cod2 ran better when affinity was set to use only 1 core.

Setting cod2mp.exe (v1.3) to use 4 cores improves my game massively.

"open task manager do it that way" - i'm aware this fixes it but this is exactly what i'm trying to avoid doing.
