Textures don't show up and the world is missing if I enable both. I see they released a patch for x1000 cards to run both. Is there no community patch that allows this?

Also, I've seen a few youtube videos where the intro demo loop looks great.... on my game it always looks like dogcrap and doesn't seem to use any of the graphical settings I choose -- despite the ingame graphics updating. Is there a reason for this?
