If you experience texture jittering in FS and you have a Nvidia Card this might help. Go into your driver panel
and make shure the value "Image Settings" (below antialiasing and anisotropic filtering) is set to "high quality".
Since I have a TFT I had this strong jittering in detailed textures when flying higher altitudes. I always had this
value set to "high performance". I red in a Games Magazine
that higher performance settings may cause texture jittering
. I tried with high quality and the jittering was gone !!
If you have such isues... give it a try.
