Dhurdahl: Your running XP Pro on a PIII 600??? You should seriously think about an upgrade! I was running Win ME on a PIII 550 up till about 4 months ago and then I upgraded the MB and processor to P4 2.4, 512mb PC2700 ram, with XP Home and OMG what a difference how smoothly the game ran!
I was running on a Radeon 64mb 7200 (latest drivers). AO was running awesome then I got into the NW beta... every time I went to play Notum Wars I would last about 1-3 minuts then crash to the point I has to re-boot (this was every, single, time!). Now, mind you I could play regular AO just fine... just NW crashed...Weird?
So I upgraded to a GF4 440 64mb and with the latest drivers I am able to play almost... problemless. SOmetimes I crash when zoneing but it is a known issue and thay are "working on it"
Good Luck
