As we wrote earlier, the Nvidia Geforce 384.76 WHQL drivers brought a couple of fixes and Game Ready/VR optimizations for Lawbreakers “Rise Up” Beta and Spider-man: Homecoming VR but also made the quite-popular Watch Dogs 2 game unplayable since the game simply did not want to start and reverted back to the desktop.
Luckily, Nvidia was quick and the new Geforce 384.80 Hotfix drivers fix this issue. There aren't any other fixes or improvements, at least according to the release notes.
If you are playing Watch Dogs 2 and want the latest Geforce drivers with all fixes and optimizations from Geforce 384.76 WHQL version, you should head to Nvidia's support page where these are available for Windows 10 and Windows 8.1/7 in both 32-bit and 64-bit versions.
