I told my GPU to prefer maximum performance and I switched from borderless full screen to regular full screen. I don't know which of those (if either) made the difference but I can now get into the game. And as long as it keeps working, I don't care :P. Thanks for the suggestions, though. I've still got the missing textures though. I'm starting a new game, so both that I've seen are in Helgen. I've got a black texture on the wooden post between the main gate and the gate's frame. And I've got a purple texture on the floor at the top of the tower you run into that the dragon knocks a wall out of (only after the dragon knocks out the wall). Any ideas? I've tried disabling dyndolod, smim, and a few other texture packs, but no luck. I've confirmed the textures are there in vanilla.
