Vulkan performance regression

[jtfen86]

Sorry if this is the incorrect place to post this.. if so anyone in charge please forward this to the right place? Anyways. I'm on Manjaro KDE. My GPU is a Radeon RX 590. Seeing a humongous drop in vkmark score after building this repo and testing. Before on 22.2.4 (Manjaro Stable branch) I'd get an average score of 20000 whereas on this mesa-git I get 3500. What is going on? That's a shockingly low drop.

That sounds like a huge regression indeed. This package is nothing special code wise, it's just using straight up mesa-git, so such a drop can only be an upstream regression of sort. Currently the github mirror for mesa is stuck in november, so you might want to switch to freedesktop (see https://github.com/Frogging-Family/mesa-git/blob/master/customization.cfg#L87). Also you might want to enable LTO for performance through the dedicated option in exchange for longer compilation (https://github.com/Frogging-Family/mesa-git/blob/master/customization.cfg#L61).

Also, as a side note, if you switched to Wayland, vkmark will perform extremely poorly vs Xorg.

The 17k score I just posted a few days ago was from a then up to date mesa git build from the freedesktop.org gitlab, from Gnome Wayland. Should I be expecting an RX 480 to score much higher?
