This is an occasional crash on what appears to be an nvidia worker thread when a game loading thread trys to create textures while the main thread is rendering. The more threads this is attempted with the more often it happens. Serializing calls to createtexture2d appears to avoid the problem. But CreateTexture2D should be threadsafe according to the api documentation.
