AMD late-Tuesday silently posted a WHQL-signed version of Radeon Software Adrenalin 19.8.1 drivers that it originally released as a Beta on August 12. The new 19.8.1 WHQL drivers, released on 20th August, are the first proper WHQL drivers since AMD’s Radeon RX 5700-series launch. Besides WHQL, the underlying code is identical to 19.8.1 Beta, and hence the changelog is untouched. TechPowerUp confirmed with AMD that there are no underlying code changes, and that WHQL signing is the only change. Adrenalin 19.8.1 adds Microsoft PlayReady 3.0 DRM standard compliance to Radeon RX 5700-series GPUs.
The new Radeon Software Adrenalin 19.8.1 WHQL drivers are available online at the AMD driver download page.
