I feel like a dummy asking this question, but I need clarification. According to the Minimum requirements for Civilization V, it lists the NVidia cards it supports. Ref: Aspyr Support Page I have a Geforce 9400. Does this mean in the Mac OS it is not supported? It lists the 8600 card, but it would seem dumb that a newer card would be backwards compatible but I'm probably wrong. Please help. Thank you!
