I recently created a Bootcamp partition on my 2012 Retina MacBook Pro, where I installed Windows 8.1 with the suggested BootCamp drivers. The installation went smooth without a single hitch. However, things aren't working as they should: I have no sound, the graphic drivers for the Nvidia GT 650M are only listed as "Microsoft Basic Graphics" or something like that, and the trackpad does not seem to work only on a very basic level (no multitouch, for instance). I have already tried to reinstall the drivers, to no avail. Am I missing something? The drivers I downloaded are the recent ones, aren't they? I found another version, but these are meant for later MacBook models.
