According to the release notes provided by Intel, this is the launch driver for three new games, including Warhammer 40K: Gladius, Relics of War, Defiance 2050, and the Banner Saga 3, bringing all the necessary optimizations for these games to work on Intel UHD Graphics 620 or better IGP.
In addition to these three hot games, the new Intel Graphics Driver for Windows 10 brings support for BlazBlue Cross Tag Battle, Lust for Darkness, and The Awesome Adventures of Captain Spirit, all of which should work on Intel Iris Pro Graphics or better GPU.
Intel also has a dedicated site where you can check out the recommended game settings for PC games, which is a nice addition as it gives you a starting point in tweaking the game to be playable on Intel IGPs.
The new driver also brings several bug fixes, including graphical anomalies in DOTA 2 when using Vulkan API, color anomalies when minimizing and restoring HDR playback on Intel 7th generation CPUs or higher, and corruption or incorrect rendering of video images with Adobe Creative Cloud products.
