AMD has released the latest version of Radeon Software Adrenalin. Version 21.9.1 is feature-packed with stuff enthusiasts are bound to love. To begin with, it introduces Smart Access Memory (PCI Resizable BAR) support for AMD Radeon RX 5000 series (RDNA) graphics processors, when used with a compatible platform. Next up, it adds optimization for "Call of Duty Vanguard Open Beta," and "Deathloop." The drivers also add a handful Vulkan API extensions, including VK_KHR_zero_initialize_workgroup_memory, VK_KHR_shader_integer_dot_product, VK_EXT_shader_atomic_float2, and VK_EXT_load_store_op_none. Perhaps the biggest new feature addition is AMD Auto Overclock.

On machines with AMD Ryzen 5000 series processors and Radeon RX 6000 series graphics, the Auto-Overclock feature detects CPU load, and automatically overclocks it in increments of 50 MHz, beyond the processor's rated maximum boost frequency. Just like manual overclocking, this comes with sizable costs to power consumption and cooling. The feature also automatically overclocks your RX 6000 series GPU. Using the feature is as easy as pulling up the Tuning tab in Radeon Software, and clicking on "Auto Overclock" in the Tuning Control tab. Lastly, Adrenalin 21.9.1 adds support for the upcoming Windows 11 operating system. The software is released alongside AMD's latest 3.09.01.140 Chipset Software, which also add Windows 11 support.
