According to a rather extensive summary brought by Sasa Marinkovic, Head of VR and Software Marketing at RTG, which you can also see in the video below, AMD brought five big updates on the consumer side, including the Enhanced Sync, which is a display technology which helps minimize screen tearing while decreasing latency and stuttering at an unlocked frame rate. According to AMD, which tested it on Radeon RX 580 graphics card, Enhanced Sync brought up to 34 percent lower latency (lag) and up to 92 percent lower frame variance in Overwatch. 

AMD also optimized driver frame watt-times which improved general game responsiveness as well as updated the Radeon WattMan with memory underclocking and power state controls.

The Radeon ReLive got camera transparency, refined notifications, and enhanced audio controls as well as support for bitrates up to 100Mbps for recording or capturing. The Radeon Chill has been updated with support for DirectX 12 and Vulkan APIs, multi-GPUs, Hybrid Graphics and Radeon XConnect Technology systems. This brought extended battery life on some notebooks.  

AMD also fixed some previous problems with Mass Effect Andromeda and HDR displays, bugs with fan speeds when using Radeon WattMan, video playback issues with AMD FreeSync and a few issues with Radeon ReLive.  In addition to these updates, Radeon Settings got a slight overhaul with Switchable Graphics, Color Depth, and Pixel Format settings moved from "additional settings" to standard Radeon Settings. 

AMD did not forget game developers either and has brought updates for Open Capture and Analytics Tool (OCAT) as well as the Radeon GPU Profiler (RGP), a hardware event visualization tool which allows developers to get in-depth access to a GPU and analyze the performance.

 
As always, you can download the latest Radeon Software Crimson ReLive Edition 17.7.2 WHQL-certified drivers from AMD's support page. According to AMD, the new drivers support all graphics cards since Radeon HD 7700/HD 7900 days and are available for Windows 10 and Windows 7 OS in both 32-bit and 64-bit versions. Bear in mind that AMD no longer supports Windows 8/8, so those running on that OS can use Windows 7 driver.
