Supercharge Your AMD Gaming on Omarchy OS – Dependencies, ProtonGE & GameScope Setup!
INSTALL SCRIPT FOR AMD BELOW
INSTALL SCRIPT FOR AMD BELOW
I test Omarchy OS on AMD hardware — specifically an i7-13700 system with an AMD Radeon RX 9060-XT class GPU — and discover why Steam games fail to launch out-of-the-box on AMD.
Please Visit this Video the full Multi system Games Installer has been release the link to the script in the description of that video ...its a massive update over the old version in the video
This is something many viewers reported, and I finally saw the issue myself when switching from my usual Ryzen 9 + NVIDIA 5060 Ti setup to my son’s AMD gaming PC. Steam installs, but no games run. Even lightweight titles like Dredge won’t launch. Cyberpunk 2077 won’t boot at all.
Turns out: the Omarchy Steam installer only pulls NVIDIA dependencies, not AMD ones — so AMD users are left with a broken Steam install. 
So I wrote a script to fix the entire stack.

🔹 What This Video Covers
• Why Steam fails on AMD GPUs in a clean Omarchy install.
• Demonstration of the issue:
• Dredge → Black screen / no launch
• Cyberpunk 2077 → No launch
• What dependencies are missing and why AMD behaves differently from NVIDIA.
• Installing my updated AMD Gaming Script:
• Installs all missing AMD Vulkan + Mesa packages
• Installs Steam correctly
• Installs ProtonGE
• Installs GameScope
• Adds Gamescope launch shortcuts
• Includes optional CachyOS kernel switcher
• Full GameScope experience:
• Press Super + Shift + S → Instant “Steam Deck style” GameScope mode
• Press Super + Shift + R → Exit to desktop
• FPS test inside GameScope on AMD:
• Dredge runs perfectly
• Cyberpunk 2077 runs with correct frame pacing
• Comparison with launching games through the normal Steam desktop:
• Still broken, low FPS, and rendering issues
• GameScope fixes it all

🔹 Why AMD Needs Extra Steps
NVIDIA includes its own “full stack” of Vulkan, OpenGL, and compute drivers.
AMD relies on Mesa, which Omarchy’s one-line Steam installer does not fully install.
You need extra Vulkan, 32-bit, and RADV components that aren’t included in the AUR entry.
My script fixes this by installing:
• mesa / mesa-vulkan-*
• vulkan-radeon
• lib32-vulkan-radeon
• game-devices-udev
• ProtonGE
• gamescope
• Optional: CachyOS Bore kernel (slightly smoother frame pacing)

🔹 Benchmark Highlights
Cyberpunk 2077 (1440p, RT Ultra, FSR)
• ~46–48 FPS on AMD GPU
• Slightly lower than NVIDIA (by ~2 FPS)
• RT performance on AMD still behind DLSS, but very playable
⸻
🔹 Why GameScope for AMD on Linux
Valve designed Steam Deck and the new Steam console around GameScope.
Launching games inside GameScope:
• Fixes rendering bugs
• Fixes odd window sizes
• Fixes FPS drops
• Enables Steam Deck menus (Ctrl+1 / Ctrl+2)
• Creates a consistent fullscreen experience
This is how Steam wants PC Linux gaming to work moving forward.

💬 Final Thoughts
If you install Omarchy OS on an AMD GPU system and nothing launches — it’s not your hardware and not Omarchy’s fault.
The Steam installer simply doesn’t pull the AMD dependencies.
My script installs everything properly and adds a full Steam Deck–style launcher so AMD users can finally enjoy the same experience as NVIDIA users.
If you have an AMD card and Omarchy OS, this is the fix.
Let me know your FPS numbers in the comments — especially if you’re running 7800XT, 6800XT, or 9000 series GPUs.
