Hey guys. I have some problems with my Anti-Aliasing in FSX. I run a GeForce 9600 M GT 512 MB. The problem was that when I turned on Gamma Correction and Anti-Aliasing mode on "Make the program setting better" and the setting at 16xQ, it would barely work in FSX at all. Example: (This is with 16x Anisotropic Filtering too, with the FSX filtering setting at Trillinear and Anti-Aliasing not enabled in game)
The Sharpen settng in Irfanview made it look better than it did in-game though.

And this one was with all the same above, just with AA enabled in the game.

Looks great and sharp in the second one, huh? Well, no problem, I thought, when I first saw how sharp it was with the AA turned on in the game. Then I noticed a drop of 6 FPS. That is not very good as I'm already down to 15-10 FPS in AI crowded areas. I can't stand flying with 6 FPS, but also, having stairs on an airplane tail just doesen't look right. But the drop in FPS wasn't the worst. The weird in-game AA made my mouse marker transparent too! What is this? The only way I can see where I'm turning in my altitude hold and speed hold etc. is when I disengage full-screen mode. That's not fun turning full-screen on and off just to change the heading or speed of my aircraft.

Hope you can help! My OS is Vista Home Premium 32-bit, if that helps.

Edit-I tried nHancer and all it's things too, even turned it at 32Q, helped just as much as normal card at 16Q.

Thanks a lot NickN, that helped me! Now to try my normal settings in big places with this.. only tried at VHHH now and that was with a steady 23-25 FPS.. in VC it was 14-18.

Thanks for your help!
