Whenever I change my settings in the effects menu and then click to apply, the textures on the ships disappear for a few minutes. I can still see the ships but they are just grey untextured blocks. They come back after a bit and it doesn't really affect gameplay for me since I'm usually zoomed out. I'm thinking when I change the settings, the vid card clears all the old texture memory to reload the new textures. I'm running on a radeon x1800 256mb
