Probably the most fundamental change of the Nvidia 381.22 graphics driver is support for a bunch of new Vulkan extensions, thus adding an extra layer of support for Vulkan, which in these days is more and more used in popular games. However, this was only implemented for the Linux driver. Another interesting change of the Nvidia 381.22 graphics driver is compatibility with newer Linux kernel branches, such as Linux 4.10 or 4.11, but it’s not mentioned in the release notes so you’ll have to test this on your own. Moreover, OpenGL threaded optimizations have been disabled by default, due to it not being stable.
