Can I Run Clair Obscur: Expedition 33?
Clair Obscur: Expedition 33 is one of the most striking RPGs to land on PC in years, and it carries the visual ambition to match. Built on Unreal Engine 5 with Lumen lighting, Nanite geometry and a painterly Belle Époque art direction, it pushes hardware harder than its turn-based combat might suggest. The good news is that it is far from the most punishing UE5 game on the market. The bad news is the same as it is for every Unreal Engine 5 title: traversal stutter, shader compilation hitches and heavy GPU load at native resolution are all part of the package unless you set things up correctly.
This guide breaks down the real PC requirements, what each tier actually delivers, how the game scales across 1080p, 1440p and 4K, and the exact settings that turn a stuttery experience into a smooth one. If you want a quick yes-or-no answer before reading further, run your rig through our Can I Run it tool and check the live verdict for your CPU and GPU. Everything below explains the why behind that verdict.
Official PC System Requirements
Developer Sandfall Interactive published official specs at launch, and they line up closely with what we have measured in testing. The figures below reflect the confirmed requirements, not predictions. Expedition 33 released in 2025, so these numbers are stable and well understood by mid-2026.
| Component | Minimum (1080p / 30 FPS) | Recommended (1080p / 60 FPS) |
|---|
| OS | Windows 10 64-bit | Windows 11 64-bit |
| CPU | Intel Core i7-8700K / AMD Ryzen 5 3600 | Intel Core i5-11600K / AMD Ryzen 5 5600X |
| RAM | 16 GB | 16 GB |
| GPU | NVIDIA GTX 1070 / AMD RX 5600 XT | NVIDIA RTX 2070 Super / AMD RX 6700 XT |
| VRAM | 6 GB | 8 GB |
| Storage | 55 GB SSD | 55 GB SSD |
| Upscaling | DLSS / FSR recommended | DLSS / FSR Quality |
A few things stand out. An SSD is effectively mandatory because Nanite streaming and the engine's asset paging hammer storage during traversal. The minimum spec assumes upscaling is on and quality settings are low, so a GTX 1070 will not give you a clean native-1080p experience. And while 16 GB of system RAM is listed across both tiers, 32 GB is the sensible target in 2026 for any UE5 game running alongside a browser and a launcher.
Why Unreal Engine 5 Demands So Much
If your hardware sits above the recommended tier but the game still feels rough, the engine is usually the culprit rather than your parts. Three UE5 systems drive most of the load:
- Lumen global illumination handles dynamic lighting and reflections without baked lightmaps. It looks gorgeous in Expedition 33's painted environments, but software Lumen alone can cost 20 to 30 percent of your frame budget, and hardware Lumen on RT-capable cards costs more.
- Nanite virtualized geometry lets the artists pack enormous detail into rocks, architecture and foliage. It scales well, but it shifts pressure onto the GPU's geometry pipeline and increases VRAM and streaming demand.
- Shader compilation and traversal streaming are the source of the dreaded UE5 stutter. The first time a new shader or area loads, the engine can hitch. Expedition 33 does a precompilation pass on first launch, which helps, but you will still see occasional traversal hitches on weaker CPUs.
Performance by Resolution
Expedition 33 is GPU-bound at higher resolutions and increasingly CPU-sensitive at 1080p with high frame rate targets. Here is what to expect from current 2026 hardware at High settings with the appropriate upscaler set to Quality. These are realistic targets, not best-case marketing numbers.
| Resolution | Entry GPU (60 FPS) | Smooth 60-90 FPS | High-refresh 100+ FPS |
| 1080p | RTX 4060 / RX 7600 | RTX 5060 / RX 9060 XT | RTX 5070 / RX 9070 |
| 1440p | RTX 5060 Ti / RX 9060 XT | RTX 5070 / RX 9070 | RTX 5070 Ti / RX 9070 XT |
| 4K | RTX 5070 Ti / RX 9070 XT | RTX 5080 / RX 9070 XT | RTX 5090 |
At 1080p the game is comfortable on midrange cards. A current-gen 60-class GPU clears 60 FPS at High with room to spare, and stepping up to a 70-class card pushes you into high-refresh territory for a 144 Hz monitor.
At 1440p, the sweet spot for most 2026 builds, an RTX 5070 or RX 9070 holds a smooth 60-plus at High with DLSS or FSR Quality, and a 5070 Ti or 9070 XT comfortably reaches into the 90s.
At 4K the picture is honest: native 4K with Lumen is brutal, so upscaling is not optional. An RTX 5070 Ti or RX 9070 XT delivers a steady 60 with DLSS Quality, while the RTX 5080 and 5090 are the cards to beat for a locked high-refresh 4K experience.

Best Settings to Fight UE5 Stutter
The default presets are not tuned for smoothness, and a handful of changes deliver most of the visual quality at a fraction of the cost. Apply these in order.
- Turn on upscaling first. DLSS for RTX cards, FSR for Radeon and Intel Arc, set to Quality at 1440p and 4K, Balanced if you are pushing a high-refresh target. This is the single biggest performance lever and barely affects image quality. If you are unsure which upscaler your card supports and how they differ, our DLSS vs FSR guide breaks it down.
- Set Global Illumination to High, not Epic. Epic Lumen is the heaviest single setting in the game. Dropping to High recovers a large chunk of GPU headroom with a minimal visual hit in most scenes.
- Cap your frame rate. A frame cap a few FPS below your monitor's refresh, combined with a sync solution, dramatically improves frame pacing and reduces the perception of stutter. Capping at 60 on a 60 Hz panel is one of the most effective smoothness fixes in any UE5 title.
- Keep Textures as high as your VRAM allows. Textures are nearly free on FPS as long as you have the VRAM. Stick to High on 8 GB cards and Epic on 12 GB and above.
- Lower Shadows and Effects one notch. These give back a few frames with little visual cost. Foliage and view distance can stay high since Nanite handles them efficiently.
- Let the shader precompilation finish. On first launch, wait for the compilation pass to complete before playing. Skipping it guarantees worse early-game stutter.
Build Recommendations
If you are buying or upgrading specifically for Expedition 33 and other UE5 games in 2026, prioritize a strong single-thread CPU, a fast NVMe SSD and a GPU with at least 12 GB of VRAM. A Ryzen 7 9700X or 7800X3D paired with an RTX 5070 or RX 9070 is an excellent 1440p machine that will stay relevant for years. For 4K, step up to a 5070 Ti or 5080.

Frequently Asked Questions
Is Clair Obscur: Expedition 33 well optimized on PC? It is one of the better-optimized UE5 games, with a built-in shader precompilation pass and reasonable scaling. It still exhibits the engine's characteristic traversal stutter on weaker CPUs and slow drives, but a capped frame rate and an SSD largely eliminate it.
Do I need a ray-tracing capable GPU? No. The game runs on software Lumen, so older cards like a GTX 1070 can play it. Hardware Lumen on RTX and RX 7000/9000 cards improves lighting quality and reflections but is not required.
How much VRAM do I really need? 6 GB is the floor for 1080p with reduced textures. For a comfortable experience with High or Epic textures, target 8 GB at 1080p, 12 GB at 1440p and 16 GB at 4K.
Will an SSD make a difference? Yes, a significant one. Nanite streaming and asset paging rely on fast storage. A SATA SSD is the minimum; a PCIe NVMe drive noticeably reduces traversal hitching and load times.
Can a Steam Deck or handheld run it? It is playable on a Steam Deck and similar handhelds at low settings with FSR, but expect a locked 30 FPS target rather than 60. The newer RDNA-based handhelds handle it more comfortably.
Is 16 GB of system RAM enough? It meets the requirement, but 32 GB is the better choice in 2026 to avoid stutter when running a launcher, browser and overlay alongside the game.
Conclusion
Clair Obscur: Expedition 33 is demanding but fair. If you have a current-gen midrange GPU like an RTX 5060 or RX 9060 XT, a six-core or better CPU and an SSD, you will run it well at 1080p or 1440p with upscaling enabled. For a smooth 1440p High experience, an RTX 5070 or RX 9070 paired with a Ryzen 7 9700X is our recommended target, while 4K gamers should reach for a 5070 Ti or 5080. The single most important step for anyone is to enable DLSS or FSR and cap your frame rate, which together neutralize most of the UE5 stutter this game is capable of producing.
