My guess is it would work.
As for the patch.... it's not a cheap trick unless:
-It cripples AMD processors
-It enables features which will run on both....only for the intel processors
If it increases performance on intel chips because of some architecture quirk they have, without hurting AMD performance, this is no bad thing.
In all possibility, it could be as you described, adding a feature just for intel chips which will still work on AMD ones, but until I see otherwise, this patch is a good thing.
And Fuku2..... that scares me
EDIT: now I'm fairly convinced it is not one sided.
Call of Duty 2 by Infinity Ward - retail v1.01 HTT patch
This Call of Duty 2 update is recommended for Windows 2000/XP users with Intel Hyper-Threading Technology (HT Technology) enabled processors, multiple processors, or systems with a dual core processor. This update will bring any supported version of Call of Duty 2 up to version 1.01. This upgrade will not affect pure server, and will not affect your ability to join or host multiplayer games with version 1.0 players.
Infinity Ward worked closely with Intel to improve Call of Duty 2 performance on systems with HT Technology, multiple processors, or dual core processors. If you do not know whether you have a multi-processor, dual core, or HT Technology enabled system, please see the ReadMe file for simple instructions on checking your system.
Please note that Call of Duty 2 is a very graphically intense game. The greatest performance increase from this upgrade will be realized by selecting Optimal System Settings in the Options menu.
This update supports US/UK English, French, German, Spanish, Italian, Polish, and Russian language versions of Call of Duty 2 only.
It divides up some work to make it run better on multicore CPUs. Since Intel's HTT tech emulates this, they get a moderate boost even on a single core system. It looks like a good step toward making Dual Core CPUs mainstream. So in my opinion: Nothing but good.
