WindowsXP and the service pack are installed together from the same cd on a new Maxtor disk. Other 3D games are working fine (Mafia, Medal of Honor, Impossible Creatures, Age of Mythology). I' ve used a utility named Riva Tuner to fine tune my card. Through this program the Detonator drivers i use (40.72) are recognizing my card (GeForce 3 Ti 200 128MB) as a Nvidia Quadro card. Do you think that this might be the problem?
