The best Once Human settings make the game easier to read before they make it prettier: stable FPS in busy towns, cleaner aim in fights and fewer visual effects hiding loot, enemies or survival warnings.
Key points
- Once Human is available on PC through Steam and Epic Games Store, with French interface and subtitles listed on Steam.
- Steam recommends Windows 10 64-bit, 16 GB RAM, GTX 1060 6 GB/RX 580/Intel Arc A380 and strongly recommends an SSD.
- NVIDIA confirms DLSS 3, DLAA and Reflex support and says DirectX 12 is required for those options in Once Human.
- The April 27, 2025 official Steam post warns mobile players that high frame rate plus high graphics may cause overheating or lag.
Once Human mixes open-world survival, third-person shooting, base building and online co-op. That means your setup has to survive long sessions, not just look good in a quiet corner of the map. For more gaming coverage, check our articles, latest updates and news category.
Key Takeaways
- Start with a stable FPS cap, then raise visual settings one by one.
- On NVIDIA RTX PCs, DLSS and Reflex require DirectX 12 according to NVIDIA.
- Lower shadows, volumetric effects and post-processing before reducing textures.
- Keep controls consistent: low to medium sensitivity and no unnecessary acceleration.
- On mobile, avoid combining high frame rate and high graphics if your device overheats.
Once Human best settings for stable FPS
Test settings in a demanding place: a settlement, a weather-heavy area, a boss zone or a base with many objects. A high FPS number in an empty field does not matter if combat turns into uneven frame pacing.
The Steam page lists Windows 10 64-bit, 8 GB RAM and a GTX 750 Ti 4 GB or Radeon RX 550 as minimum requirements. Recommended specs include 16 GB RAM and a GTX 1060 6 GB, RX 580 or Intel Arc A380, with an SSD strongly recommended. In a survival game built around travel and loading assets, that SSD note is important.
| Problem | Recommended setting | Reason |
|---|---|---|
| Uneven FPS | Cap at 60, 90 or 120 depending on your display | A stable cap feels better than wild spikes. |
| GPU pressure | Medium or low shadows and effects | These settings hit hard in combat and weather. |
| Late textures | Match texture quality to VRAM and use an SSD | Reduces delayed loading during exploration. |
| Input delay | Disable V-Sync if VRR works correctly | Can reduce latency when paired with a clean FPS cap. |
- Use native resolution first, then lower render scale only if needed.
- Set a cap your PC can hold in busy areas.
- Lower shadows and test a real fight for several minutes.
- Reduce volumetric effects, heavy post-processing and bloom if drops continue.
- Keep textures high only when VRAM is not saturated.
- Restart after switching graphics API or major presets.
DirectX 11, DirectX 12, DLSS and Reflex
NVIDIA states that Once Human supports DLSS 3, DLAA and NVIDIA Reflex, and that players should switch the Graphics API setting to DirectX 12 to use DLSS and Reflex. If you have an RTX GPU, this is the first setup to try.
Still, treat the result as a test. If DirectX 12 causes crashes, big FPS drops or heavy stutter after several minutes, compare it with DirectX 11 in the same location. The best setting is the one that stays stable through a full farming route or boss attempt.
Use DLSS Quality at 1440p or 4K if the image stays clean. Move to Balanced only when performance needs it. Avoid pushing graphics too high and then masking the cost with aggressive upscaling: in Once Human, enemy silhouettes, ground hazards and resources must stay readable.
Enable Reflex when available, especially for PvP, boss fights and public events. If you use Frame Generation, watch the actual feel of aiming and dodging, not only the FPS counter.

Graphics settings for survival visibility
Once Human can become visually noisy: Stardust particles, weather, vegetation, red lights, monsters, loot prompts and ruined terrain all compete for attention. A cinematic image is not always a useful image.
Disable motion blur if possible. It makes fast turns and enemy movement harder to read. Reduce depth of field if you often scan for loot, resources or distant threats. Keep anti-aliasing or DLSS in a mode that does not smear silhouettes.
Very high shadows are rarely worth the cost. They add mood to forests and bases, but they can darken corners and cost frames in the exact places where you need clear visibility.
| Option | Readable setting | Avoid |
|---|---|---|
| Motion blur | Off | Leaving it on for style during fights. |
| Shadows | Medium | Very high on a limited GPU. |
| Post-processing | Low to medium | Bloom and filters hiding details. |
| Textures | High if VRAM allows | Ultra if assets pop in late. |
| View distance | Medium to high | Too low if you scout resources at range. |
Controls for aiming, looting and surviving
Once Human best settings also include controls. You need to aim, dodge, heal, swap weapons, open quick items and manage inventory without fighting the input layout.
On mouse, choose a sensitivity that allows a quick turn without destroying small aim adjustments. Disable acceleration where possible and keep your DPI consistent across shooters. On controller, tune deadzones carefully: too high feels sluggish, too low creates drift.
- Put healing, food, water and ammo on quick access.
- Keep dodge on a button you can press without losing aim control.
- Separate interact and reload if you often grab items by mistake.
- Test keybinds in a hostile area before a boss or public event.
Interface, audio and long-session comfort
Readable UI prevents deaths. Make health, stamina, ammo and survival statuses easy to scan without covering the center of the screen. If you play on a TV or far from the display, increase UI scale carefully.
Raise effects slightly and lower music if you miss enemy cues. In co-op, keep voice chat audible but not louder than attack sounds. Camera shake and heavy visual feedback should be reduced if they make long farming sessions tiring.
Mobile settings: heat before image quality
The developers have acknowledged mobile graphics and performance issues in an official Steam announcement. They also warn that high frame rate and high graphics together may cause overheating or lag depending on the device.
- Pick high FPS only if the device stays cool after fifteen minutes.
- Lower graphics before sacrificing UI readability.
- Close background apps and avoid long sessions on fast charging.
- Clean up touch controls so heal, dodge and weapon swap sit under your thumbs.
- On tablets, check resolution scaling because large screens can increase GPU load.
Pre-boss and farming checklist
Before a risky boss, PvP run or long farming route, do one quick pass. It catches problems before you carry valuable loot.
- FPS cap holds in a busy area.
- Motion blur is off.
- Shadows and effects are lowered if fights drop frames.
- Healing, food, water and ammo are on quick access.
- Effect audio is high enough to hear attacks.
- PC or mobile temperature is stable after fifteen minutes.
- DX12, DLSS and Reflex were tested, or DX11 is selected if more stable.
Frequently Asked Questions
What should I lower first if Once Human stutters?Lower shadows, volumetric effects and post-processing first. Keep native resolution until you have tested those cheaper wins.
Yes. NVIDIA says DLSS and Reflex require switching the Graphics API setting to DirectX 12 in Once Human.
Enable it when available, especially for boss fights, PvP and any setup using DLSS or Frame Generation.
Use the highest cap your system can hold consistently: 60 for stability, 90 or 120 for smoother displays if your PC can sustain it.
Install the game on an SSD, lower textures if VRAM is full and close heavy background apps.
Disable motion blur, reduce bloom and post-processing, avoid overly dark shadows and keep silhouettes sharp.
Avoid high FPS plus high graphics by default, lower quality, close background apps and test heat away from fast charging.
Steam currently lists Steam Deck compatibility as unsupported, so expect extra testing and possible issues.
Use the official Steam news hub, the Steam page and NVIDIA’s DLSS note.
Prioritize stable FPS and controls first. Better visuals are only worth it if aiming, dodging and looting remain consistent.
