AMD Releases Radeon Software Adrenalin 18.9.3

AMD today released the latest version of Radeon Software Adrenalin Edition. Version 18.9.3 beta comes just in time for "Assassin's Creed: Odyssey," posting up to 5% higher performance at 1440p, when tested with a Radeon RX Vega 64; and up to 3% higher performance at 1080p, tested with an RX 580. The game also comes with optimization for "Forza Horizon 4," although AMD did not put out performance guidance for that game. AMD also addressed a couple of issues, beginning with fixing a stutter observed when exceeding FreeSync refresh-rate range in some high frame-rate scenarios. Also addressed is machines with 16 CPU cores experiencing a random system reboot during driver installation, when upgrading from 18.8.1 drivers. Grab the drivers from the link below.

The change-log follows.
