The fix is to force the CoD2 exe file to only use one processor core, but that doesn't mean the problem is exclusive to multicore processors; the same thing happens even on a Pentium 4 with Hyperthreading. Note that opening the Task Manager after starting the game and setting the process CPU affinity from there does not work. We have to get a little more involved than that. One last thing: the following directions are for the singleplayer exe file. If you find you need to apply this fix to multiplayer as well simply repeat the steps for CoD2MP_s.exe.
CoD2MP_s.exe
CoD2SP_s.exe
imagecfg -u CoD2SP_s.exe
-u
On some systems the game won't start on Windows Vista, 7 or higher.

Compatibility mode (Windows XP (Service Pack 3))
Because running in compatibility settings give DirectX some unnecessary flags, in game fps can be highly reduced on some systems.
In the graphics option menu, set the "Rendering Method Preference" to DirectX 9.
DirectX 9
If the game crashes when trying to change the renderer, either modify the game's configuration file manually with a text editor or apply compatibility settings (see Game won't start on Windows Vista and 7 for details).
