I've had Skyrim installed on my PC for a few weeks and it was running perfectly, until Dawnguard came out. I have not purchased Dawnguard yet, but could this glitch be somehow related? Do I need to install Dawnguard to fix it, or will that make it worse?
The green blocks show up everywhere, with every save file, I even tried to start a new game and it was still happening. I have all the settings on low, all the drivers are up to date and such, and I only had one mod installed, which was the free high resolution texture pack from Steam. I got rid of the texture pack to see if that might help, but no such luck.
I am totally at a loss. What do I do next? Why did this just randomly start happening, after the game ran so smoothly before? Is this something I can fix, or is it just Skyrim being Skyrim and I need to wait for a patch? I'm really frustrated that I spent so much money on a product that doesn't work properly.
