AMD Round Out August With The 20.8.3 Radeon Driver Update

👤by Tim Harmer Comments 📅29.08.2020 23:54:18



August is giving way to September and AMD are concluding it with their third graphics driver update of the month. Radeon Software Adrenalin 2020 Edition 20.8.3 optimises support for Marvel's Avengers, Fortnite and Project CARS 3, broadens Vulkan API compatibility, and implements a handful of fixes to known issues in games and other software.

This latest driver update is strictly optional rather than heavily recommended. You only need install it if you plan of playing any of the listed titles in the near future or suffer from the fixed issues outlined in the release notes. A more comprehensive update, aggregating this and future changes into one more rigorously tested release, will follow soon.

The specific optimisations for Marvel's Avengers and Project CARS 3 aren't spelled out, but likely reflect weaknesses in the driver stack uncovered during beta testing. AMD are a little more forthright about Fortnite, stating that the drivers improve DX12 rendering performance for Epic's FPS Battle Royal by an average of 12%. That's based on testing with an RX 5700XT so your own mileage may vary.



Support for four new Vulkan functions will no-doubt aid performance and stability in future titles developed with the API, but are unlikely to have any immediate impact in games played right now.

And, of course, fixing a healthy number of known issues is always welcome in any driver release. This time AMD's sights are a little more broad than in previous updates, addressing critical flaws experienced when playing five different games and FreeSync 2 HDR implementation problems.

Still more issues have been identified for their internal hit-list, particularly underlying performance and stability concerns for their driver background application. RSAE 20.8.3 won't fix them, but hopefully an upcoming release will in the very near future.

The Radeon Software Adrenalin 2020 Edition 20.8.3 can be downloaded from AMD.com/support by selecting your hardware and OS. This driver supports 64-bit versions of Windows 7 and 10, and is compatible with graphics hardware dating back to the HD7000-series (GCN era).

VK_GOOGLE_user_type
- This extension indicates the driver’s support for shader modules using the SPV_GOOGLE_user_type SPIR-V extension.

Fixed Issues

- Mortal Shell™ may experience a game or application crash when opening the inventory window in game.
