Clair Obscur Performance Guide After Patch 1.5.0 – Best Steam Deck, ROG Ally & PC Settings for Smooth FPS

Clair Obscur: Expedition 33 is a visual stunner—an Unreal Engine 5 showcase packed with striking art direction and atmosphere. But for many players on Steam Deck, ROG Ally, and PC, that beauty once came at a cost: inconsistent FPS, stutters, and immersion-breaking performance issues that held back an otherwise award-winning RPG.

That problem is finally solved.

Fresh off its Game of the Year win, developer Sandfall Interactive dropped its massive “Thank You” update (Patch 1.5.0)—and it completely changes how Clair Obscur runs. The game is now officially Steam Deck Verified, optimized for ROG Ally, and significantly smoother across PC thanks to major engine-level fixes and new upscaling options.

This guide breaks down:

What Patch 1.5.0 actually fixed
The best Steam Deck settings for stable performance
Recommended tweaks for ROG Ally and PC players
How to unlock Clair Obscur’s full visual potential without sacrificing smooth gameplay

📈 Official Performance Fixes in Patch 1.5.0

Before touching any settings, it’s important to understand the strong foundation Patch 1.5.0 provides. These are official changes, not workarounds—and they’re the reason the game finally runs well on handhelds.

Platform Performance Improvements

Platform	Key Improvements
Steam Deck & ROG Ally	• Official certification: Steam Deck Verified and ROG Ally optimized • 30 FPS cap removed • VSync can now be properly disabled • Fixed UI scaling and text readability issues • Stabilized heavy lighting and fog zones (e.g., Endless Tower)
All PC Platforms	• Added AMD FSR 4 support (temporal upscaling + frame generation) • HUD scaling options (80%–120%) • Full controller input remapping

These fixes alone dramatically improve stability—but the real gains come from proper configuration.

⚙️ Ultimate Steam Deck Optimization Guide

Clair Obscur Performance Guide After Patch 1.5.0

The default Steam Deck Verified profile is stable, but it’s conservative. It locks away many graphics options and applies aggressive visual downgrades. For the best balance of image quality and performance, one small tweak is essential.

Step 1: Unlock the Full Graphics Menu

Add the following launch command in Clair Obscur’s Steam properties on your Deck:


SteamDeck=0 %command%

This single line removes the locked-down preset and gives you full access to all graphics and rendering options, including quality presets and advanced controls.

Step 2: Apply the Optimal Steam Deck Settings

After enabling the full graphics menu, use the following configuration:

Setting	Recommended Option	Why It Works
Graphics Preset	Low	Best performance baseline with better visuals than the locked default
Upscaling Type	TSR (Temporal Super Resolution)	Most stable image quality, especially in late-game areas
Upscaling Quality	Low or Balanced	Low = best FPS, Balanced = strong middle ground
Frame Rate Target	30 FPS / 90Hz	Crucial for combat timing and parry consistency
HUD Scale	120% (Accessibility menu)	Ensures clean, readable text on the Deck’s screen

Performance Expectation:
With these settings, expect 30–35 FPS during exploration and combat. The world map may see brief dips, but overall performance is smooth and visually impressive.

By comparison, the default locked Steam Deck mode can hit 30–45 FPS, but only by heavily cutting visual quality—making it a poor trade-off.

🖥️ Advanced PC Performance Tips & General Fixes

For desktop players, Patch 1.5.0 introduces powerful new tools—most notably AMD FSR 4, which offers sharper upscaling and smoother frame generation on supported GPUs.

If you’re still seeing stutters or crashes after updating, try these proven fixes:

Verify Game Files
Use Steam or Epic Games Launcher’s repair function.
Update GPU Drivers
Perform a clean install of the latest drivers from NVIDIA, AMD, or Intel.
Check System Stability
Temporarily disable RAM overclocks (XMP/EXPO) and GPU undervolts. Unreal Engine 5 can be sensitive to aggressive tuning.

💎 Final Recommendations: Choose Your Ideal Setup

Your best configuration depends on how you prefer to play:

Plug-and-Play Simplicity
Use the default Steam Deck Verified setup. You’ll get stability with minimal setup—at the cost of visual fidelity.
Best Overall Handheld Experience
Use the launch command and optimized settings above. This delivers the definitive Steam Deck and ROG Ally experience, balancing performance and visual quality.
Maximum PC Performance
Enable FSR 4 if your AMD GPU supports it, and experiment with Frame Generation for ultra-smooth gameplay.

🏁 Final Thoughts

Patch 1.5.0 transforms Clair Obscur: Expedition 33 from a demanding technical showcase into a polished, portable masterpiece. Whether you’re playing on Steam Deck, ROG Ally, or PC, these optimizations finally let the game’s artistry shine—without stutters getting in the way.

With the right settings, nothing stands between you and the RPG that took home Game of the Year.
