Okay. I have the ATI 2600 XT graphics card (pci-E) and Windows XP Pro. With FSX, I thought there was a place within FSX to enable Directx10. I dont see that place yet. So, not sure if DX10 is running. Do I need Vista installed instead of XP?
You've gotta be running vista in order to run dx10. Not really worth the upgrade IMO
