is it possible to make the aircraft textures set the very high including VC and have all other textures outside the aircraft on a different level?I just wanted to know so i can get good performance from flying withing the VC

Yes. In your FSX settings page, you have a tab for aircraft where you can select whether you want a high resolution 3D VC or not. Then you have a tab for scenery which you can adjust sliders for resolution of scenery textures, etc.Best regards,Jim
