Mesa 19.2 RADV Driver Now Fully Supports EXT_sample_locations For Possible AA Benefits
Months ago was some minimal work around handling VK_EXT_sample_locations in RADV but now Samuel Pitoiset of Valve has landed a series of patches into Mesa Git for properly plumbing this extension in Mesa. VK_EXT_sample_locations has been around since Vulkan 1.0.60 and allows an application to modify the location of samples within a pixel for rasterization. Applications / game engines can specify alternative sample locations for each pixel in a group of adjacent pixels to allow for possible anti-aliasing quality improvements.
Now after all the prep patches, the extension is enabled for Mesa 19.2 due out next quarter and one more Vulkan extension to cross off the TODO list.
This is one of the Vulkan extensions that has been supported by AMD's official Vulkan driver but not by RADV until today.
