I experimented a lot already, but I cannot get any AA and AF to work when they're set in the NVidia control panel and disabled in FSX. Only when I put "application controlled" in the fields of the NVidia control panel and enable AA and AF in FSX, I get AA and AF. I also installed NHancer, which had no effect, so I uninstalled it again.The same works with an ATI adapter where I get at least AA with the driver when AA is set to off in FSX. The adapter gives slightly better results in AA than FSX built-in AA. So, I'd like to do the same with my NVidia adapter.I have a NVidia GTS-250. Is there any way to let the graphics driver control AA (i.e. disable FSX built-in AA) with my video adapter?Andreas

What drivers do you have? Reason I ask is because you should reinstall nhancer, but I believe only the beta version works with the latest vnidia drivers. After you install nhancer, there is a guide floating around here somewhere the explains how to properly set up the profile for FS. If someone knows the link they can post it.

That's funny. I have never been able to get aa to work with CCC with my ati card. Af does work however.When I go away from app controlled, I get no aa but I do get a frame rate hit that is worse than application controlled. I have used several drivers.
