Intel has released a new graphics driver for 6th Generation Core processors onwards that is available now to download for Windows 10 devices. The driver has been optimised for the release of Football Manager 2019, and brings performance improvements and fixes for several other games including Warhammer Vermintide 2 and Assassins Creed Odyssey among others.

I have a hard time believing Assassin's Creed Odyssey is even remotely playable at any half-decent settings on Intel IGFX.
