-*BAD WORD*- if you did not know this...XP Home likes your ram.if you have 256 ram xp will use 125+ of it.Try shuting down prgs that your not using. Hmmmzzz, well it crossed my mind...also the fact that other games like say Unreal Tournament II and Knights of the Old Republic actually run and don't hog my CPU have crossed my mind. These games use alot more memory than CNL. It isn't a RAM-problem, although i agree that XP uses more than it probably needs, but in this case it's not the problem. MM progammed it in 3DRad, to my knowledge it's a game creator program...which is tested on all platforms. So with that in mind i don't think it has to do with the progam itself. Well with all the obstacles out of the way i guess you can think of the reason why CNL in it's current state isn't running on *all* platforms. -*BAD WORD*-,(to use your words), i haven't seen a single post that someone actually played it. This is in no way an offense to MM himself...i'd like to see it working! (i hate to quote myself and others) Again, good luck! S2K.
