Why graphics settings matter in Once Human
In most PC games, your GPU is the limiting factor. In Once Human, that’s often true—especially when you push higher resolutions, enable expensive lighting/shadow features, or stack multiple post-processing effects. The CPU can also bottleneck when there’s heavy simulation, lots of entities, or dense areas, but GPU-related settings usually dominate average FPS.

Before you change anything: prerequisites and quick checks
Confirm your hardware baseline
Before touching settings, note three things: your GPU model, your CPU model, and your display’s refresh rate (60/120/144/165/240 Hz). Your target FPS should match what your monitor can show without tearing or stutter.
- GPU: e.g., NVIDIA GeForce RTX 4060 / RTX 3070, AMD Radeon RX 7600 / RX 6700 XT
- CPU: e.g., Intel Core i5-12400 / AMD Ryzen 5 5600
- Display: 1080p/1440p and refresh rate (like 144 Hz)
Use a repeatable test scene
Performance tuning is only useful if you measure consistently. Choose the same in-game area (or benchmark route), then test 2–3 runs after each major change. If you can, enable an FPS counter and keep it on while you adjust.
Make sure your game files are healthy
If you’re seeing sudden drops, missing textures, or constant stutter even after lowering settings, verify game files in your launcher (Steam/Epic/etc.). Corrupted assets and broken shader caches can mimic “bad settings.”
How to choose your target FPS and resolution
Pick a goal before you configure. If your monitor is 144 Hz, targeting 140–144 FPS is ideal but not always practical. A “feels great” target for most PCs is usually 90–120 FPS at 1080p or 70–100 FPS at 1440p, depending on your tolerance for input latency.
A practical decision rule
- If you want maximum smoothness: target near your refresh rate and reduce the most expensive settings.
- If you want best visuals: target a stable FPS (like 60) and use upscaling/resolution scaling to keep it consistent.
- If your FPS is inconsistent: focus on frame pacing (V-Sync strategy, cap FPS, and reducing settings that cause spikes).
Resolution guidance
Native resolution is the most expensive choice. If you’re GPU-limited, 1080p with high-quality image settings often beats 1440p with aggressive drops. Resolution scaling (when available) can give you the best balance of clarity and performance.
Core in-game graphics settings (what they control and how they affect FPS)
Once Human’s exact option names can vary by build, but most PCs will have a similar set of categories. Use this mapping to understand what to change. When in doubt, reduce or disable the features in the order listed below.

- Equipped with a blazing fast Core i5 2.00 GHz processor.
Settings that usually cost the most GPU time
| Setting category | What it affects visually | Typical performance impact |
|---|---|---|
| Shadows (quality, distance, cascades) | How detailed and far shadows render | High |
| Volumetrics (fog/cloud density/god rays) | Light shafts, atmospheric depth | High |
| Ambient Occlusion (AO) | Creases and contact shading | Medium to High |
| Post-processing (bloom, motion blur, film grain) | Stylization and screen-space effects | Medium |
| Anti-aliasing (TAA/FXAA) | Edge smoothing and stability | Low to Medium |
| Textures (texture quality, texture streaming) | Surface detail and sharpness | Low to Medium (mostly VRAM/streaming) |
| Anti-aliasing + resolution scaling | Overall clarity vs. GPU load | Medium (depends on the scaler) |
| Environment detail (foliage/mesh density) | How busy scenes look | Medium (sometimes CPU-bound) |
Core options to set in a sensible order
- Resolution / Render Scale: choose 1080p or 1440p target; if scaling exists, start at a moderate value (often 90–100%).
- Upscaling tech (if available): enable NVIDIA DLSS or AMD FSR if your GPU supports it; choose the quality mode that preserves detail.
- Shadows: lower quality and shadow distance first.
- Volumetrics / Atmospheric effects: reduce density and quality to stop FPS spikes.
- Ambient Occlusion: set to low/medium; disable if you still can’t hit your target FPS.
- Anti-aliasing: use TAA-style smoothing if available; otherwise prefer a moderate AA option over heavy post effects.
- Post-processing: keep bloom moderate; turn off motion blur if it feels distracting or you want sharper motion clarity.
- Textures: set texture quality high if your VRAM allows it; if you stutter with high textures, step down one level.
Presets you can start from (and how to tune them fast)
Most players benefit from starting at a preset (Low/Medium/High/Ultra) and then making a small number of targeted changes rather than flipping everything one-by-one.
Preset start points by goal
- Competitive / high FPS: start from Medium or High, then reduce shadows + volumetrics.
- Balanced visuals: start from High, keep textures high, lower AO and shadows to medium.
- High fidelity on capable GPUs: start from Ultra, then verify frame pacing and reduce post-processing if you see spikes.
Fast tuning workflow (the 10-minute method)
- Set resolution and V-Sync / frame cap once (don’t change them every step).
- Pick a preset that gets you “playable” FPS (even if visuals aren’t perfect).
- Reduce Shadows and Volumetrics until your FPS is stable (less variance frame-to-frame).
- Raise Textures or Anti-aliasing a step if you have extra headroom.
- Only then adjust Post-processing and AO for final feel.
Best settings by hardware tier
The most reliable “best settings” are those that hit your target FPS with minimal spikes. Below are practical stacks you can use as starting points—then fine-tune shadows/volumetrics first if your results differ.
Entry-level (1080p, 60 FPS target)
Typical hardware: GTX 1660 Super / RTX 2060, Intel i5-8400, AMD Ryzen 5 2600. Aim for stable 60 FPS with minimal stutter.
- Resolution: 1920×1080
- Upscaling: if available, use Quality/Balance mode
- Shadows: Low (distance reduced)
- Volumetrics: Low or Off
- Ambient Occlusion: Low or Off
- Anti-aliasing: TAA/medium if available
- Post-processing: keep bloom on low/medium; disable motion blur
- Textures: Medium (or High if VRAM allows)
Mid-range (1080p–1440p, 90–120 FPS target)
Typical hardware: RTX 3060/4060, RX 6600 XT/7600, Ryzen 5 5600, Core i5-12400. This tier benefits heavily from keeping shadows under control while using AA and/or upscaling.
- Resolution: 1080p for maximum headroom; 1440p if you can sustain it
- Upscaling: Quality for 1440p, Performance/Balance for tougher scenes
- Shadows: Medium (distance medium)
- Volumetrics: Medium
- Ambient Occlusion: Medium
- Anti-aliasing: TAA on
- Post-processing: bloom medium; motion blur off if you prefer sharpness
- Textures: High if you avoid VRAM pressure
High-end (1440p, 120–160 FPS target)
Typical hardware: RTX 4070/4070 Ti, RX 7800 XT, Ryzen 7 5800X3D / Core i7-12700K. You can push visuals while still staying smooth, but volumetrics and shadows can still spike.

Choose an upscaling mode based on artifacts
- Quality mode: best image stability; ideal if you can mostly hit your target FPS.
- Balanced/Performance mode: better FPS but may introduce shimmer on thin geometry (wires, fences) or ghosting in motion.
V-Sync and FPS caps: how to avoid “almost smooth” gameplay
Uncapped FPS can cause uneven frame pacing. Capping FPS often feels better than chasing the absolute maximum.
- If your FPS is above refresh rate: consider capping slightly below refresh rate (e.g., 141 FPS on a 144 Hz monitor) to reduce tearing and jitter.
- If your FPS is below refresh rate: use a cap that matches your ability (like 90 or 60) rather than letting it bounce wildly.
- If you see input lag: try disabling V-Sync in-game and using a driver cap, or switch to a lower-latency sync strategy.
Motion blur decision
Motion blur can hide low FPS, but it also reduces perceived sharpness during tracking. If you’re sensitive to blur or you play shooters/action games, turning it off usually improves clarity and makes stutter easier to notice (so you can fix it).
Driver and Windows settings that commonly improve results
Settings inside the game matter most, but driver-level and Windows-level settings can reduce stutter and improve consistency.
Free tools Windows power users keep installed
One-click scans. No signup required.
NVIDIA Control Panel (typical best-practice setup)
Use this only if you’re comfortable with driver settings; revert if you see odd behavior.
- Open NVIDIA Control Panel.
- Go to Manage 3D settings > Program Settings.
- Select Once Human if listed; otherwise add it from the game executable.
- Set Power management mode to Normal (or Prefer maximum performance if you’re chasing stability and your system stays cool).
- Set Vertical sync to Off if you plan to control V-Sync in-game; otherwise leave it consistent with your in-game choice.
- For low-latency tuning, consider Low Latency Mode = On (or Ultra, if available) and test; if it causes artifacts, switch back.
AMD Radeon Settings (typical best-practice setup)
AMD’s menu names vary a bit by driver version, but the workflow is the same.
- Open AMD Software: Adrenalin Edition.
- Go to Gaming > Graphics.
- Select Once Human from the game list.
- Set Radeon Chill to Off for consistent FPS.
- Set Enhanced Sync only if you understand the tradeoffs; otherwise keep sync handled consistently in-game.
- Ensure your upscaling choice is consistent (don’t fight between game and driver).
Windows settings that reduce hiccups
- Set your power plan to High performance (or Balanced if you already get stable clocks).
- Enable Game Mode (Windows Settings > Gaming > Game Mode).
- Consider Hardware-accelerated GPU scheduling (Graphics settings) if it’s available in your Windows build; test both ways because results can vary by system.
- Update GPU drivers to a stable version released around your timeframe (avoid old drivers if the game recently added patches).
Troubleshooting: when your FPS is low, stutters, or looks wrong
When tuning doesn’t solve it, the problem is usually one of three categories: wrong render path (upscaling mismatch), stutter from caching/shaders, or a thermal/power limit.

Problem: low FPS even on Low settings
- Check resolution scale: if render scale is above 100% (or supersampling is on), drop it to 100%.
- Confirm GPU usage: use Task Manager (Performance tab) during gameplay to see if your GPU is actually busy. If CPU is pegged, you may need to reduce CPU-heavy settings like crowd/entity density.
- Reset settings: some games keep stale shader options after updates. Try a “Reset to default” then retune.
Problem: stutter after 5–20 minutes
- Shader compilation: first-run stutter is common. Let the game run through one longer session after a driver update.
- Texture streaming pressure: if you lowered textures too far and stutter worsens, try stepping textures back up one level or enabling texture streaming (if it’s an option).
- Thermals and clocks: watch GPU temperature and clock behavior. Thermal throttling can mimic “random stutter.”
Problem: shimmering / crawling edges
- AA + upscaling mismatch: if you use an upscaler, don’t stack extra sharpening or aggressive post-processing if it exists in the pipeline.
- Reduce sharpness: if there’s a sharpening slider (common alongside upscaling), try lowering it slightly.
- Prefer TAA: TAA-based AA generally reduces shimmering on thin geometry compared to FXAA-style approaches.
Problem: washed-out colors or strange contrast
- Check HDR: if HDR is enabled in Windows or game settings, ensure it’s consistent with your display.
- Post-processing overrides: disable film grain and heavy contrast/tonemapping effects temporarily to isolate the culprit.
- Driver color settings: reset any custom color profiles in GPU control panels.
Problem: crashes or hard resets after changing settings
If the game becomes unstable after a setting change (especially resolution scale or upscaling mode), step back to the last stable configuration and update your GPU driver. Also verify game files to rule out corrupted settings data.

- Changing 10 settings at once. You can’t learn what caused the gain or loss if everything changes together.
- Maxing shadows while ignoring volumetrics. Shadows and volumetrics both cost, but volumetrics often causes spikes in complex scenes.
- Ignoring VRAM limits. High textures can push VRAM over the edge and cause stutter. If you see hitching in busy areas, lower textures before lowering resolution.
- Forgetting frame pacing. Uncapped FPS can look fast in benchmarks but feel inconsistent. Use a sensible cap.
- Running conflicting sync systems. Decide where V-Sync (or frame pacing) is handled: in-game or driver—not both fighting.
FAQ
Should I use DLSS/FSR in Once Human?
If the game offers it and your PC supports it, upscaling is usually the best value for FPS. Start with a Quality or Balance mode and compare edge stability in motion. If you see heavy shimmer or ghosting, step to a higher quality mode or reduce sharpening.
What’s the first setting I should lower if my FPS drops in fights?
Shadows and volumetrics are the usual first wins. They often affect both GPU load and scene complexity, so lowering them reduces spikes when combat heats up.
Is 1440p better than 1080p if my GPU struggles?
Not necessarily. If 1440p forces you into frequent drops or stutter, 1080p with good AA and stable frame pacing usually feels better. A consistent frame rate beats an ambitious resolution.
Why does the game stutter after I changed settings?
Shader caches and texture streaming may rebuild. Give it a short session to settle, and verify game files if it behaves abnormally. Also check if you introduced a resolution scale or upscaler mismatch.
What FPS cap should I use?
A good starting point is your refresh rate minus 2–3 FPS (for example, 141 for 144 Hz). If you can’t sustain that, cap slightly lower where the frame time stays consistent—60 or 90 are common stability targets.
Bottom Line
The best Once Human graphics settings aren’t a single universal profile—they’re a balance between stable frame pacing and the few visual features that cost the most FPS. Start with resolution and upscaling, then reduce shadows and volumetrics before touching textures or anti-aliasing.
Use the 10-minute workflow, test in the same scene, and cap your FPS to prevent “almost smooth” stutter. Once you dial in stability, you can push quality a step at a time without risking performance regressions.
