AMD Radeon Prepares for Horizon Zero Dawn's PC Launch with RSAE 20.8.1

👤by Tim Harmer Comments 📅05.08.2020 22:08:59

Horizon Zero Dawn finally arrives on PC at the end of the week and AMD are ready with a day-0 driver update for their range of Radeon Graphics hardware. Radeon Software Adrenalin 2020 Edition 20.8.1 is the first update of the month and incorporates optimisations for Horizon Zero Dawn Complete Edition in addition to broader support for the early access test builds of Hyper Scape and Grounded. Plus, it also rectifies for a range of important issues.

Guerrilla's open world title may be the biggest game launch of the month and should look gorgeous with high fidelity textures rendered at or above the 30fps PS4 standard, so a pre-launch driver optimisation pass is especially welcome. With luck it will mean that even the first round of players will have an excellent experience on any flavour of modern Radeon hardware, but that also relies on the skill of developers in porting to PC.

AMD sometimes include performance improvement metrics for their driver updates, and such is the case for Grounded when running on RSAE 20.8.1. Running on the Epic in-game graphics preset their internal tests indicate that the Radeon 5700 XT operates 9% faster than with the 20.7.2 driver; no mean margin, and hopefully reflected down the preset options and AMD's product stack.

Seven fixed issues are specifically highlighted in this driver's release notes, encompassing a range of problems from game specific to detrimental experiences with Radeon Software features. If you have encountered any of those outlined then it would be advisable to update your drivers as a priority.

AMD also identify a dozen issues in need of solving which should be addressed in a coming update.

The Radeon Software Adrenalin Edition 20.8.1 is compatible with 64-bit versions of Windows 7 and 10, and supports graphics hardware as far back as the HD 7000-series (GCN). Download it at or via the Live Update functionality of the Radeon Software desktop app.
