Vulkan performance regression
jtfen86 opened this issue · 3 comments
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.
mesa-tkg-git 23.0.0_devel.164534.22bf19c1f51-1
_mesa_prs="15642 19502 19947 20050 20207 20226"
Oh, and kernel command line:

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?
