While there are no performance boost or new profiles, the new Geforce 391.05 Hotfix driver, according to the release notes, fixes both display corruption issues on the Titan V graphics card as well as the "stopped working" bug with the Nvidia Freestyle tool. It also adds support for Microsoft Surface Book notebooks.

As expected, it also includes all improvements from the latest Nvidia WHQL-certified driver, the Geforce 391.01, so in case you are not suffering from any of the aforementioned problems, there is no need to update your driver.
