PSA: you should probably avoid NVIDIA driver 384.76 if you intend to play Watch Dogs 2. Many who have updated to that version on Ubisoft’s forums are complaining about the sequel crashing on startup. A hotfix driver will be released as early as next week, however. (I finally bought the first Watch Dogs game off the Steam Summer Sale and have no idea why it was so poorly received when it first came out; it is actually really fun.)
