Intel Arc B580 on Omarchy OS – LM Studio, DaVinci Resolve & Steam Gaming Test

In this Linux Out of the Box episode, I test Omarchy OS 3.2 on an Intel Arc B580 system — including AI performance with LM Studio, creative work in DaVinci Resolve, and gaming performance through Steam + GameScope.

Omarchy doesn’t ship with the full Intel ARC driver stack, so I use my WOPR Games Launcher and Resolve installer to build a complete AI + creator + gaming environment. Everything shown here is from a clean install.


⸻

🔹 System Tested


• Dell XPS 8960
• Intel i7-13700
• Intel Arc B580 GPU
• Intel UHD iGPU (auto-detected)
• Omarchy OS 3.2 (Hyprland)

🔹 LM Studio (Local AI) on Intel Arc B580

Installing LM Studio via Install → AI → LM Studio works perfectly.
With the WOPR driver stack installed, LM Studio correctly detects:
• ✔️ Vulkan
• ✔️ Vulkan Compute (Vulkan-C++)
• ✔️ Ability to load larger LLM models

Without the extra dependencies, LM Studio does NOT detect Vulkan and forces you onto tiny 8GB models — confirmed during the first launch.


This makes the Arc B580 surprisingly capable for local AI work.

🔹 DaVinci Resolve on Intel Arc

DaVinci Resolve installs cleanly using the Resolve script, then:
• ✔️ First launch scaling fixed by setting UI to 150%
• ✔️ Resolve initially picks the wrong GPU (UHD iGPU)
• ✔️ Switching to the Arc B580 works immediately
• ✔️ OpenCL detected
• ✔️ No hardware encoding (expected for Resolve Free)

Export options available: ProRes, MP4 (AVP), AVI, etc.
No AV1 export for ARC on the free version.


Overall: Resolve is fully usable on Intel Arc for timeline editing and colour work.

🔹 Steam + Gaming (GameScope Mode)

After attaching my games SSD and logging into Steam, I launch gaming through the WOPR Launcher:

Keybinds:
• Super + Shift + S → Enter GameScope
• Super + Shift + R → Exit GameScope

GameScope creates a Steam Deck–style fullscreen mode that runs far better than desktop Steam.


✔️ Dredge
• Launches instantly
• Works perfectly
• This game does not run at all on a base Omarchy install without the WOPR scripts

✔️ Ball Pit
• Vulkan Shaders load correctly
• Runs smoothly in GameScope

✔️ Night Rain
• Anti-cheat warning displays
• Game launches successfully
• Running at ~47 FPS @ 1440p High
• After tweaking reflections / motion blur, performance improves


Important:
Base Omarchy install → Games do not launch on ARC
WOPR script installed → Everything launches first try

🔹 Why ARC Needs Extra Drivers

Omarchy’s default Steam installer only includes NVIDIA stacks.
Intel ARC requires:
• Vulkan
• lib32-vulkan
• Level Zero
• VAAPI support
• ProtonGE
• GameScope
• MangoHUD
• GamesMode

The WOPR Launcher installs all of these automatically.

💬 Final Thoughts

Intel Arc B580 + Omarchy OS is genuinely impressive:
• LM Studio detects Vulkan and runs local AI models
• DaVinci Resolve works with OpenCL
• Steam games run flawlessly in GameScope
• Performance is good for a budget GPU
• The only requirement is installing missing ARC dependencies

For a ~£200 GPU, this setup works far better than expected.
