I have my AA and AF settings on my ATI control panel and not in the sim. I have an ATI Radeon x800 pro card. When you first boot into the sim everything is fine. If you exit and come back the AA and AF settings are gone and everything is jagged. Why do the settings go away? I have to reboot the computer and then go into the sim to get my settings back. I don't get it. Can anyone enlighten me on what I'm doing wrong? I'd appreciate any help.Lee

Lee,I have had the same kind of problem recently.When you say "exit and come back", you mean, alt-tab to the desktop and come back to FS9 again without closing it down?If yes, it is the same problem as mine.The only thing that I suspect could be the problem is that I installed the update for Dx9 (october release) and did not update the ATI driver afterwards.Did you happen to have done the same?Thank you for your feedbackGhiom

Turns out it may be an ATI glitch. My new rig arrived and it has an Nvidia card and I can exit and re-enter FSX many times and AA and AF settings are always there.Lee
