In my mind DOW is not really playable! I have played a lot of it on my Desk Top (P4 2.8 gig of ram and Nvidia 6800GT) and when it gets busy it gets a bit jerky! The NC10 tricked me as it started off running great and I was amased but it got jerky pretty soon and got jerky enough to stop me enjoying it. I’m not going to say its unplayable but I feel it is more fun to just play another game that is nice and smooth!
If you want a 3d RTS game then get Age of Mythology! It looks fantastic and only gets a little jerky when very busy! (6 players all in the same fight)
I play these things in multi player only tbh so maybe singel player is diferent but I doubt it!
