Can your PC run Once Human? (System requirements and FPS tips)

Here is the thing most people miss about Once Human: the minimum specification is genuinely old hardware, and the recommended tier is achievable on mid-range PCs from several years back.

Official system requirements

Starry Studio's confirmed Windows PC specifications cover both a minimum and a recommended tier. The minimum specification targets lower resolutions and reduced settings, while the recommended tier targets a smoother experience at 1080p.

What each hardware tier actually delivers

The minimum specification is honest about what it offers. A GTX 750 Ti or RX 550 with an i5-4460 and 8 GB of RAM runs the game at reduced settings and lower resolutions. This level of hardware is roughly eight years old or more, so most systems built since then clear it without issue.

The recommended specification at a GTX 1060 with an i7-7700 and 16 GB of RAM delivers a noticeably smoother experience at 1080p with higher settings enabled. Independent benchmarks on hardware above the recommended tier, including modern mid-range GPUs paired with 16 to 32 GB of RAM, show frame rates comfortably above 60 in most areas.

Settings guide by hardware tier

Once Human runs on the NeoX Engine, which scales across a wide range of settings presets. Players on older hardware can run the game at reduced settings without major visual loss in most outdoor areas.

1. 1
   Check your RAM first 8 GB meets the minimum but 16 GB noticeably improves stability during transitions
2. 2
   Match your GPU to the table above GTX 750 Ti or RX 550 covers minimum, GTX 1060 or better covers recommended
3. 3
   Lower resolution before lowering core settings Resolution scale recovers performance with minimal visual impact
4. 4
   Close background applications on minimum spec systems Frees memory for smoother loading during transitions
5. 5
   Use an SSD if available Not required but reduces load times and texture streaming delays

Storage and what it actually affects

Once Human requires roughly 50 GB of storage on PC, with periodic updates adding to that figure. A recent major update added approximately 15 GB on top of the base install.

An SSD is not strictly required but is recommended by the developer. Running from a mechanical hard drive is possible but results in longer load times and slower texture streaming during exploration.

Hardware below minimum and what to do

If your system falls below the listed minimum, particularly on GPUs older than the GTX 750 Ti or RX 550, the game may still launch but stability and frame rates will likely suffer in busier areas. Lowering resolution scale and reducing settings to their lowest values is the first step before considering a hardware upgrade.
