Cyberpunk 2077 on Asus ROG Ally X with SteamOS 3.8 | Optimized Settings + Battery & Temps Test

In this benchmark, I test Cyberpunk 2077 running on the Asus ROG Ally X with SteamOS 3.8 – Valve’s Linux-based gaming OS.

This is not your average gameplay. I use my custom optimized settings, multiple resolution modes, and real performance measurements including temperatures, battery life, and full overlay stats.

Watch this if you’re planning to play Cyberpunk on your ROG Ally X with SteamOS — or if you’re curious how it compares to Windows!

🔧 Tested Settings Timeline:

1:30 — My optimized in-game settings

2:20 — 1920×1080 Performance Mode

6:03 — 1600×900 Performance

8:30 — 1280×720 Performance

10:00 — 1920×1080 Balance Mode

11:42 — 1920×1080 Performance (again for comparison)

12:10 — Testing DLC: Phantom Liberty

19:23 — Full system overlay activated

🔍 My Observations:

In Performance mode (42W TDP), the ROG Ally X runs 10°C cooler on SteamOS than on Windows — from 91°C down to 80°C.

Battery Life:

Performance mode: ~1 hour 30 minutes

Balance mode: ~2 hours

OS used: SteamOS 3.8

🔧 Tested with Proton compatibility and Lossless Scaling OFF.
