Phoronix: Vulkan Video Now Enabled By Default For Radeon VCN2/VCN3 Hardware On Linux

An exciting merge today for the Radeon "RADV" Vulkan driver with next quarter's Mesa 25.0 is enabling Vulkan Video API support by default for AMD graphics having VCN 2.x and VCN 3.x hardware...

I trust this brings us one step closer to the day when I can play 24fps content on a 75hz VRR display and it'll automatically frame-triple to 72hz...

Cool, so you can finally play videos you bought 25 years ago with hardware you bought 5 1/2 years ago.

Why would you need to triple your frames? Typical VRR goes down to 48 Hz and everything below is automatically doubled by the display.

It's 23.976, but there is also a possibility that range of some VRR displays start at 47.952.

I am confused. I configured Chrome to use Vulkan video on AMD on Mesa 24.3 and AMD 6800. It works for me, but from that article it looks like it should not work.

Great, but this will be gimped in the Fedora and OpenSUSE Mesa builds just like we deal with today.

What do you mean? Not disagreeing, just curious

Vulkan Video and VA-API are not the same thing, the Chromium project has not implemented anything regarding Vulkan Video yet.

1. What the previous post said. This will only allow you to use Vaapi on Wayland while also using Vulkan - in theory. Questionable if it already does both.
2. Vaapi and Vulkan Video exclude each other. Question only is how various task managers will display the hardware usage from Vulkan video. Technically it should look identical, so the only place that can show you what is used will be logs.
