Intel Arc Battlemage experience
Edit: I went back and tried kernel 6.13 rc5 and nothing changed.
I got a B580 today and decided to write a small write up of my experiences so far to help others decide if they want to try to grab one or not.
I have mesa-git installed from copr, and everything else is just stock Fedora 41 Workstation (I went back and tried kernel 6.13 too with no changes) with the resizable bar enabled (you'll need this feature if you're looking into getting one of these cards). Interestingly, running dmesg | grep BAR= doesn't show anything with the Intel card installed, but it does for my Vega Frontier. I'm not sure what's causing this. Maybe I'm checking it wrong?
The B580 booted right up, and mostly everything seemed fine. However, I noticed some weird stuttering in the Apps menu and occasionally when dragging windows around.
Most of my Flatpaks were unable to detect the card at all. The things I tested were Moonlight, OBS, and Kdenlive. On the other hand, Prismlauncher/Minecraft worked fine, and I got about 20 more FPS than I did with my Vega Frontier card.
I tried to add the beta branch of Flathub and install the mesa-git Flatpaks, then ran these Flatpaks again using the command FLATPAK_GL_DRIVERS=mesa-git flatpak run "flatpak". Unfortunately, this didn't change anything.
All the games I tested in Lutris (non-Flatpak) worked great. I ran Diablo 2 Resurrected, WoW, and Manor Lords (not the most intense games, lol).
Virt-manager with Spice/Virtio and 3D acceleration did not work at all. I just got a black screen on my VMs.
If you have any questions or know of anything I can try to fix any of the issues I experienced, please let me know.
Edit: I tried some games in steam and they all worked wonderfully. I tried Metaphor: Refantazio, Persona 4, Nier Automata and Deadlock.
