Core Confusion!!! Any help please?

Thanks for comments. I won't do much checking, as it's very playable, even at max settings. I think the large airports are rough because of unique textures. I do some modelling, and textures are a bigger FPS killer than complex mesh/high poly counts. I don't mean to sound flippant. Fact is, I'm currently buried trying to refine textures on a current project. At present, it would probably take down a power grid. I only play enough FS to screw up the courage to get back to work
