mXDriver 16.11.5 is based on AMD’s Radeon Crimson 16.11.5 and brings the usual optimizations from AMD (newly supported games and bugfixes). On my dual D700’s with Windows 10 64-Bit it’s working flawlessly. 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 16.11.5 comes with version 1.0.26 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). If this advice does not help you please let me know in the comments section. Read more mXDriver 16.11.5. for all 64-Bit platforms since Windows 7
