Phoronix: Open-Source Radeon Vulkan Driver Now Can Run Dota 2 With Correct Rendering

David Airlie and Bas Nieuwenhuizen continue making good progress on the open-source, community-driven RADV Vulkan driver for providing Radeon Vulkan support for newer GCN GPUs in the absence of AMD making available their Linux Vulkan driver as open-source...

Well that was quick. The speed at which these guys have worked to get this far is scary, even if the code isn't well optimized at all

I also now know that LiveJournal is still a thing.

In theory to get correct picture on the screen is hard, to get 80% of the possible speed is harder and last 20% are the hardest.

CIK GPUs kinda work with the amdgpu kernel driver loaded.

freaking amazing, nice job

The progress really is stunning ... thanks a lot to Dave and Bas !

Cool! I was not expecting progress like this either. Great work! I can't wait till it's the go-to graphics API for linux.

Great news, I’m also positively surprised by the progress, although I don’t know for how long they have been working on it. I’ll still probably get a GTX 1060, but anyway…

Is AMD's Vulkan driver still coming or will this take its place?

Well, I get ~84 fps with pts on a R9 285 (~87 fps with the experimental RADV_HIZ_DISABLE=0), compared to ~90 fps with mesa, so I think we're past the 80% on this game already. The remaining difference is going to get harder though as the whole state management wrt compressed surfaces is kind of a mess currently.

It also seems that the polaris regression happened due to one of the commits that gave a significant performance boost, so we might need to do a step back for a while.

First, congratulations for the work, that was fast.

Second, if the driver is passing conformance tests, why the games are having problems? That means that the problem is with a bad implementation of Vulkan in the games? There is conformance tests for games/applications?
