I don't use the anti-aliasing in FSX, but the one of the ATi Control panel (4x).
I haven't said it's related to FSX antialiasing, it's might be related to antialiasing in general. So, you might want to try different settings.
And I use the bilinear filtering of FSX. FlyTampa suggested this setting in their manual for Kai Tak.
Once you forced the filtering settings in the video card control panel, meaning the video card setting takes precedence, setting bilinear or anisotropic in FSX doesn't change anything. However, anisotropic filtertering doesn't have an impact on the airplane panels.
But the specific "black screen" in the lower half, it's more like a *bug*, triggered by the type of antialiasing. Note, that this used to happen only with specific driver releases, and I recall being more frequent with FS9.
I already made flight from and to JFK, but with the DC-10.
And the results was ?
EDIT One more thing: I recently changed my global resolution settings from VERY HIGH to HIGH. Maybe it has also something to do with this.
This would only affect the texture sharpness. In fact, from your screenshots, you have very bad blurred texture at ground, which is not how the scenery it supposed to look like.
However, lowering the max global texture resolution, doesn't have any "bad" effect, other then blurring, but sometimes can even *fix* issues, because it lowers the vram memory requirements. So no, I don't think the loss of 2d and 3d panels and the scenery flickering were caused by this.
