Intel Arc B580 on Omarchy – Steam Deck Mode, Mesa Git & 80FPS Gaming (Arc Raiders Test)
I said the GameScope launcher didn’t work on Intel.
I said the GameScope launcher didn’t work on Intel.
So I built an Intel version.

⚠️ Mesa Git is experimental.

This video is the public release of the Intel Arc edition of my Steam Deck–style GameScope launcher for Omarchy — tested on an Intel Arc B580 12GB card.
Intel GPUs are improving fast on Linux, but they’re not plug-and-play like AMD. So this version required its own script, its own driver handling, and a few important caveats.
⸻
🔹 The Hardware
• Intel Arc B580 12GB
• 13th Gen Intel i7
• 4K display
• Omarchy 3.3.3 (stable)
The Arc cards are currently some of the best value GPUs on the market. Around £200–£220 for 12GB VRAM is hard to ignore — especially if Intel continues investing in Linux support long-term.
⸻
🔹 Mesa Git (The Big Decision)
During install, you choose between:
1️⃣ Standard Mesa
2️⃣ Mesa Git (compiled from latest source)
If you choose Mesa Git:
• It downloads and compiles (≈20 minutes)
• You get the latest Intel driver stack
• Some games that won’t launch on stable Mesa may start working
But:
• It’s experimental
• It’s system-wide
• You’ll need to recompile periodically for updates
Use at your own risk.
⸻
🔹 XESS vs FSR on Linux
Important:
• Native XeSS support isn’t fully there yet on Linux
• Selecting XeSS often falls back to a compatibility layer
• Proton Cachy can provide newer DLLs
• But you’re still not using proper Arc cores
For now:
👉 FSR is the safer choice
👉 It’s platform agnostic
👉 More consistent on Linux
⸻
🔹 Game Tested – Arc Raiders
Tested in GameScope mode:
• 1440p
• Medium settings
• FSR enabled
• Around 80 FPS
• Fully playable
It’s not 5060 / 9060 XT territory — but it’s very respectable for the price.
Doom (Dark Ages) currently runs poorly on Arc.
Most other titles tested (Cyberpunk, Homeworld, Baldur’s Gate, Night Rain) work fine.
⸻
🔹 HDR Warning (Important)
If your monitor pretends to support HDR (but doesn’t really):
⚠️ Do NOT disable HDR inside Steam’s GameScope menu.
Doing so can cause a black screen requiring manual VDF edits to fix.
This appears to be a Mesa / Intel driver issue.
⸻
🔹 Desktop vs Laptop
This version is:
• Desktop tested
• Intel Arc B-series tested
• Not tested on Intel laptop GPUs (Panther Lake etc.)
Laptop support may vary.
⸻
🔹 Is Intel Worth It?
For the price:
• 12GB VRAM
• 80 FPS at 1440p medium
• OpenCL available
• AI workloads possible (with work)
• Linux support improving
If Intel continues developing these drivers, Arc could become a very serious Linux GPU option long term.
Linus Torvalds runs one.
That’s… not nothing.
