If my AF is set to "let application decide" or what not then will having catalyst AI ennabled affect my AF quality?
Depends on the game, but I'd rather force it through the driver control panel.
And by turning it off do you mean setting catalyst AI to standard or disabling it altogether?
I mean set Catalyst A.I. to "Disabled" if you want the absolute best AF. Standard is good to and gives more fps on the average. Sometimes there is little to no visual difference when casually playing through a game. However, I prefer Cat A.I. to be disabled when I can since when it is disabled any setting, either AA or AF, gets
forced on a game if that game has said features. (i.e. NWN2 doesn't allow any AA, so setting 4xAA in the CCC when Cat A.I. is disabled won't do anything) When I feel like I need more frames I move it from "Disabled" to "Standard."
Once you select your Cat A.I.--either "Disabled" or "Standard"--rename the .exe to force Alternate Frame Rendering (i.e. CrossFire). I'm not sure exactly what the name should be, "AFR something, something.exe" or the like. I don't have CF so maybe gerrson, Matt22, Elfear, etc. could fill you in on what it would be.
