mXDriver 17.1.2 is based on AMD’s Radeon Software Crimson ReLive Edition 17.1.2 and brings the usual optimizations from AMD (newly supported games and bugfixes) as well as support Conan® Exiles Beta and Tom Clancy’s Ghost Recon® Wildlands Beta. Vulkan support is also included and gives Doom a big fps boost. Please note: Newer versions of the Vulkan API (1.0.26+) don’t work with the Vulkan Stardust Demo although other applications like Doom work great in Vulkan mode.
If you have troubles running a Vulkan application, which ran with mXDriver 16.9.1 Reloaded (Vulkan API 1.0.21), than it should be sufficient if you replace amdvlk64.dll in C:\Windows\System32 with an older version. mXDriver 17.1.2 comes with a newer version of amdvlk64.dll, to get version 1.0.21 of amdvlk64.dll you can just use the file from mXDriver 16.9.1 Reloaded. The file is located in the ZIP-Archive under Packages/Drivers/Display/WT6A_INF/B******/ (the * are placeholders for a sequence numbers which change with every release).
