Jagged lines on aircraft

Hi guys.. I am new to this forum and to flightsims.
I have a problem with FSX.
I am dutch so I don't know if this is the precise word for it.
But I have jagged lines along my plane.
Flying straight is no problem but as soon as I go up or down the horizontal line appear blocky.
I think a picture tells more then 1000 words. Check the red line on the fuselage.

My specs are AMD X2 6000+, 2GB memory, XFX 8800 GTS on win xp.
I have downloaded the latest graphic driver from the nvidia site.
I have AA on 8 (overide any application) and AF on 16. AA is enabled ingame.
My screen resolution is 1280 x 1024 x 32.
I really hope someone can help me.. it's a pretty annoying look.
