Once Human System Requirements & PC Benchmark

Can your PC survive the eldritch Stardust contamination and conquer anomalous Great Ones? Once Human, developed by Starry Studio and published by NetEase Games, is the smash-hit free-to-play multiplayer open-world survival game that blends cosmic supernatural horror with modern gunplay. Featuring deep territorial base building, bizarre Deviation companion creatures, motorcycle exploration, and chaotic 40-player Prime War world boss raids, Once Human places significant demand on CPU draw call management and GPU memory bandwidth. Use our interactive PC system requirements checker above to simulate your expected framerate before establishing your territory.

Once Human Minimum System Requirements (1080p 30-60 FPS Low)

To run Once Human at baseline playable performance (1080p resolution targeting 30 to 60 FPS on low presets in early regions), Starry Studio specifies the following minimum PC specs:

• Operating System: Windows 10 (64-bit) with the latest security updates
• Processor (CPU): Intel Core i5-4460 (3.2 GHz) or AMD FX-8300 (3.3 GHz)
• Graphics Card (GPU): NVIDIA GeForce GTX 750 Ti (4GB) or AMD Radeon R7 260X (2GB)
• System Memory (RAM): 8 GB RAM
• DirectX: Version 11 or Version 12
• Storage: 60 GB available space (SSD is strongly recommended for seamless open-world asset streaming)

Once Human Recommended System Requirements (1080p & 1440p 60 FPS High)

For a fluid 60 FPS experience at 1080p or 1440p high quality settings during complex dungeon runs and multi-squad engagements, recommended specifications call for:

• Operating System: Windows 10 or Windows 11 (64-bit)
• Processor (CPU): Intel Core i7-7700K or AMD Ryzen 5 3600
• Graphics Card (GPU): NVIDIA GeForce GTX 1060 (6GB), GTX 1660 Super, or AMD Radeon RX 580 (8GB)
• System Memory (RAM): 16 GB dual-channel DDR4 RAM
• Storage: 60 GB available space on a fast NVMe M.2 SSD

Once Human 4K Ultra Specs (60+ FPS Enthusiast Tier)

Metas playing on 1440p 144Hz or native 4K displays who want Ultra particle effects, high-density volumetric fog, and steady frametimes in 40-player Prime Wars will require an Intel Core i5-12600K or AMD Ryzen 7 5700X3D paired with an NVIDIA GeForce RTX 3070, RTX 4070, or AMD Radeon RX 6800 XT (12GB+ VRAM) and 32GB of RAM.

Best Once Human Graphics Settings to Fix Prime War Lag

While exploring the wilderness runs smoothly on modest hardware, massive world boss events (Prime Wars) feature dozens of players firing rocket launchers and placing gatling turrets simultaneously. Adjusting these settings will eliminate severe stuttering:

• Resolution Scale / Upscaling: Set to 100% Native, or enable AMD FSR / NVIDIA DLSS in “Quality” mode on higher-resolution monitors.
• Shadow Quality: Medium (High shadows heavily tax GPU memory bandwidth during multi-light nighttime encounters).
• Special Effects Quality: Medium (critical setting: Medium drastically stabilizes frametimes when dozens of elemental explosions detonate on screen).
• Vegetation Detail: Medium (reduces grass render distances without making forests look barren).
• Anti-Aliasing: TAA (eliminates harsh shimmering on chainlink fences and laboratory scaffolding).
• Motion Blur: Off (substantially enhances target acquisition while firing from moving vehicles).
• Max Visible Players / Model Quantity: Set to Medium or High (Low can make teammates invisible, while Max causes CPU queue delays).

Hardware Bottlenecks: Prime War CPU Spikes & NVMe Streaming

Once Human features an enormous seamless world with zero loading screens between towns, silos, and stronghold bases. Traversing the map on a high-speed motorcycle causes continuous texture and mesh streaming. Running from a mechanical HDD will cause noticeable hitching and invisible walls as the world loads. In Prime Wars, CPU single-thread performance becomes the primary bottleneck as the engine tracks 40 players, automated turrets, and massive boss hitboxes.

Frequently Asked Questions (FAQ)

Is Once Human playable on the Steam Deck?
Yes, Once Human can run on Steam Deck via Proton. By using Medium/Low settings, locking the framerate to 30 or 40 FPS, and setting FSR to Balanced, you can maintain playable performance for daily resource gathering and dungeon farming.

Can I run Once Human on 8GB of RAM?
While 8GB of RAM meets the minimum specification, you will experience memory paging stutters when entering heavily developed player territories with dozens of automated crafting stations. 16GB is strongly advised.

Does Once Human require a continuous internet connection?
Yes, Once Human is an online-only shared-world survival game. All character inventory, progression, and base structures are saved on dedicated regional servers.
