According to rather short release notes, the new Radeon Software Adrenalin 2019 Edition 19.3.3 driver is mostly focused on bringing day-one support for Sekiro: Shadows Die Twice and Generation Zero games.
It also fixes bugs with intermittent corruption or flickering on some game textures in Rainbow Six Siege and stutter issues when running DOTA 2 VR on the Vulkan API.
The Radeon Software Adrenalin 2019 Edition 19.3.3 graphics driver is available for 64-bit versions of Windows 7 and Windows 10 OS, and supports all Radeon Graphics cards since HD 7700/HD 7900 series, Mobility Radeon and AMD APUs with Radeon graphics.
