The latest AMD Radeon Driver release (Adrenaline Edition 18.3.1) is available now, bringing optimizations for Final Fantasy XV: Windows Edition (due to launch today) and Warhammer Vermintide 2 (launching on Thursday, though the pre-order beta is already available). The release notes also mention fixes to World of Tanks, Sea of Thieves and Middle-earth: Shadow of War issues.
What they don't list, however, are the additional benefits now available thanks to Project ReSX, or Radeon eSports experience. The goal of this project was not only to deliver performance improvements in terms of frames per second (which Project ReSX does anyway with up to 11% gains in PlayerUnknown's Battlegrounds (1080p, Ultra settings), up to 3% gains in Overwatch (1440P, Ultra settings) and up to 6% in Dota 2 (4K, Ultra settings), but also to allow more fluid and responsive gaming.
For instance, PlayerUnknown's Battlegrounds now has up to 9% lower 99th percentile frame time, Overwatch up to 2% lower and Dota 2 up to 7% lower. The most interesting improvements listed by AMD are possibly in the "click-to-response" area, where apparently Adrenaline Edition 18.3.1 will bring you up to 4% lower response in Overwatch and up to 8% lower in Dota 2.
These tests were conducted by AMD Performance Labs as of March 1st on the 8GB Radeon RX580 GPU, installed on a system also featuring the Intel 7700K CPU (4.2 GHz), 16GB DDR4-3000 Mhz RAM, Windows 10 64-bit OS.
We'll see if AMD continues to invest in Project ReSX in the future and whether its arch-rival NVIDIA becomes interested in doing the same.
