Hentzau,
This is what Cas141 had to say about running it on his system:
I run 98SE and I have fast loading, never had a CTD, nor a computer problem I can associate with WoW. Is like F B in that respect.
I think Windows 2000 is a prime suspect. Not really a "game" O. S.
Maybe someone who has Wings of War could print out the Minimum System Requirements for us here?
