AMD today released the Radeon Software Adrenalin 21.4.1 drivers, which introduce major updates to the soft-product that completes your AMD Radeon graphics cards. The drivers come with updates to the Radeon Software interface, and the AMD Link remote-gameplay utility. Radeon Software now comes with an improved installer with installation presets that let you choose between a Full (typical) installation, with all software features installed; a Minimal installation with an interface that only has basic settings related to the display and GPU; and "driver-only" that only installs the display driver, and no additional software. There are several new features introduced within Radeon Software. Vivid Gaming Display Color Enhancement is a new monitor color profile that enables a more "vivid" color palette that lets you liven up "color deficient" scenes. The interface lets you take control of protanopia, deuteranopia, and tritanopia components of the color. The search bar that lets you dig through the hundreds of features, has been improved. There are many other minor UI improvements, such as stats in the Games tab, a toggle for the in-built web-browser, and global controls for the hotkeys.

Perhaps the most talked about feature addition with Radeon Software 21.4.1, has to be the AMD Link remote-gaming feature. Until now, AMD Link was a mobile app that let you control your drivers. It's grown in functionality over the years to include game streaming. Your game, as rendered on your PC, is streamed to your portable devices such as smartphones, tablets, and smart TVs; and now AMD has also introduced a Windows app that lets you share your gameplay with anyone with the app, across the Internet. The process of sharing is very similar to that of Team Viewer. Besides gameplay, AMD Link can also let you share your non-gaming Desktop. AMD has significantly updated the streaming backend, which now offers better visuals and lower latencies, along with a dynamic quality control that adjusts quality with changes to your Internet bandwidth/latency. The service now supports up to 4K UHD resolution, with refresh-rates of up to 144 Hz.
