Phoronix: NVIDIA Ships Vulkan Driver Beta With Fragment Shading Rate Control

This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus...

Sometime, I check release version supported in my system by vulkaninfo command where I get three different kind of information:

1. Instance Version: 1.2.131
2. apiVersion = 4202629 (1.2.133)
3. conformanceVersion = 1.2.2.0

Which are the meanings of these different pieces of vulkan information?

Just different things and each have a version number. Not really going to do anything for you. You're main concern for version is to simply be on the latest driver release or not.

conformanceVersion for example is just the Vulkan Conformance Test suite version number that was used: https://www.khronos.org/conformance/adopters

Ok, thanks. Which information does indicate the vulkan version supported by my graphical card among them?

instance version is the version of the vulkan library you have on the system, apiVersion is the highest vulkan version the gfx driver supports.

Many thanks. It seems that my videocard cannot take any benefit from the latest release of Vulkan.

What do you mean about 2on the system2 and "gfx driver support"?
