Anti-aliasing

[Kiki981]

I have a problem with AA in my game. No matter what I do, it returns to be ON. I tried to change iMultisample to 0, but when I start the game, in Vivid Weathers it shows me that is back to 1. I disabled AA in Skyrim launcher, and after starting Skyrim, it returns me back to 1. I set all to disable in Nvidia control panel, but no change. I know, that AA can cause some game resources (FPS, stuttering...), so I want to disable it. On internet I read that instead AA folks should use FXAA. So In launcher I disabled AA and enabled FXAA, and problem is still there, Becouse after playing around with Nvidia CP, the game became a bit slow and started su stutter a bit. But even with all AA disable, there is no change in game. Even if I set (in skyrimpref.ini) iMultisample= 0, and when I start the game it shows me that is back to 1 (this happens when I launch game second time - first time is normally to 0). So what in hell can I do to keep it 0. Becouse in skyrimpref.ini it sets it back to 1. No matter what I do or change. And it's not something wrong vith Vivid weathers info, becouse I notice, that when is back to 1 the game becomes slower and stutters a bit. And as i read in S.T.E.P., that people should use FXAA and not AA if they have a problem with game performance. So what can I do or what should I do?
