This is what I received from emailing AMD's Tech Support:QUOTE
We here in the Technical Service Center have tested Microsoft's Combat
Flight Simulator II under various conditions and found that there is no
patch needed or required to run this game on any AMD processors. It is
unclear why Microsoft references a patch in their readme file. We
suspect they may be referencing a patch we developed for Windows 2000.
The patch for Win 2K an our Athlon processor can be found on our web
Any other patch would come directly from the S/W developer. You may
want to contact Microsoft directly to see if there is any further
Thank you...thank you very much. Now where's my fried peanut butter and banana sandwich?
