I updated with DDU because this morning I started getting crash after crash just after the Loading icon. Updated, verified files, crashed at the same place. Remembered that last night before going to bed that I had changed my desktop background to actual screenshots from the game (from a non-W3 game folder); switched back to the basic tiled gifs I had been using, and no more crash (wtf?). Will post again later about how my game acts with these new drivers.
