According to the release notes, the newest Radeon Software Adrenalin 2019 Edition 19.12.1 graphics driver, which is probably the last one before the expected big yearly driver update, adds support for Radeon RX 5300M GPU. While AMD has announced this mobile GPU back in November, we have yet to see a laptop equipped with that GPU, unless you count the new Apple Macbook Pro, which uses a Pro version of the same GPU.
In addition to the support for the Radeon RX 5300M, the new Radeon Software Adrenalin 2019 Edition 19.12.1 also fixes some minor issues with the Radeon RX 5700 series including stutter issues in some games at 1080p and low game settings, as well as an intermittent crash issue in The Outer Worlds game.
The new Radeon Software Adrenalin 2019 Edition 19.12.1 is available over at AMD's support site and supports mostly all GPUs since Radeon HD 7700/HD 7900 days, and is available for 64-bit versions of Windows 7 and Windows 10 OS.
