I'm wondering why some of my aircrafts show up with blurry textures, that vanish when I cycle through the views.So it is not a problem in the aircraft itself, a video card issue,maybe - but only a few aircrafts behave this way.Are there any tweaks I can do or tests to perform to get rid of this problem?Has anyone else experienced it?

Usually happens because the textures were created with MipMaps. You can search for and use DTXBMP to remove the mipmaps and save.

thanx mikewill do a search
