RADV vs. AMDVLK Vulkan Drivers Continue Stiff Performance Battle

With the RADV Mesa Radeon Vulkan driver continuing to be advanced by Valve and other independent developers while AMD continues with open-source code drops of their official AMDVLK Vulkan driver, it's been a friendly open-source Radeon Vulkan driver performance and feature/extension battle since that official AMD Vulkan driver was opened up at the end of last year. With new AMDVLK/XGL/PAL code drops happening about weekly and RADV continuing to receive new feature/performance work every few days, both drivers continue maturing gracefully as shown by our latest performance benchmarks.
