When I installed the demo version just after its debut, prior to FSX's initial release, I experienced abnormal graphics where autogen objects would be placed were they should not be, ie, antennae floating in bodies of water, skyscrapers in the middle of airports, floating automobiles, etc...
When FSX was finally released, I bought the Deluxe version, installed it, and experienced the same phenomenon.
I have since upgraded to Windows Vista, on a clean install. When I reinstalled FSX, I noticed this problem that I had involving both the Final Release and the demo version had disappeared. Now it seems, that my frame rate takes a massive hit when I enable antialiasing.
Currently, I have this option disabled, and am using the nVidia driver-supplied antialiasing which although is not as good as FSX, does provide something that doesn't cause graphics issues.
My question, has anybody else experienced this? Is this just an issue with my PC or is this an actual bug in the program?
