With so many games on the horizon, you can expect a frantic pace of new GPU driver releases from AMD and Nvidia. Today it was AMD that released a new Crimson ReLive 17.11.1 driver package for Radeon graphics card owners, with an emphasis on Call of Duty: WWII performance.

According to the release notes, Radeon RX Vega 64 owners should see up to a 5 percent bump in performance when running the game at 2560x1440, compared to the previous ReLive 17.10.3 release. AMD didn't produce any other stats, though we imagine the optimizations yield minor gains at other resolutions, and for other Radeon graphics cards.
