For a strong balance of image quality and frame rate in Abiotic Factor, start at your monitor’s native resolution, use High textures (Epic if your VRAM has headroom), High view distance, Medium or High effects, Medium or High shadows, Medium Global Illumination, and disabled motion blur. If the GPU is still struggling, reduce Global Illumination/Lumen first, then Virtual Shadows or ordinary shadow quality, then Effects, and only after that lower resolution scale or enable upscaling. This order preserves texture detail while targeting the settings that cost the most GPU time.
Use this balanced starting profile
The following is a practical starting point rather than a developer-certified preset. It combines Unreal Engine scalability guidance with game-specific cost measurements reported by a Steam Community tester. Apply it at your display’s native resolution, then adjust one option at a time in a busy, repeatable area of the facility.

| Setting | Starting value | When to change it |
|---|---|---|
| Display resolution | Monitor native resolution | Lower resolution scale or use upscaling only after the quality settings are sensible and the GPU remains the bottleneck. |
| Textures | High; Epic if VRAM is not close to full | Lower this when you see texture streaming problems or your graphics memory is saturated. It was inexpensive in the available game-specific test. |
| View distance | High | Reduce it if distant geometry is a larger performance problem than lighting, or if you need a small additional gain after the major GPU costs are addressed. |
| Effects | Medium or High | Lower after Global Illumination, Virtual Shadows and general shadows have been tested. |
| Shadows | Medium or High | Use Medium when shadow rendering is consuming too much GPU time. |
| Virtual Shadows | High or the game’s available middle setting | Reduce this early when GPU frame time is high; the setting can be substantially more expensive than textures. |
| Global Illumination | Medium | Lower to Low for a major performance recovery, accepting flatter lighting; raise it only when the frame rate target is stable. |
| Reflections | Use the quality level that keeps frame time stable | In Unreal Engine 5, Lumen quality is controlled through the Global Illumination and Reflections groups, so test reflections with GI rather than treating Lumen as an isolated effect. |
| Motion blur | Off | Keep it off for a sharper image and clearer motion. Turn it on only if you personally prefer the effect. |
| Frame-rate limit | A value your PC can sustain | Choose a cap below the dips you see in your normal play area instead of chasing a peak number in an empty room. |
| Upscaling | Off initially, then a quality mode if needed | Use it after choosing a reasonable preset. Resolution scale is the broadest performance lever, but it also affects the whole image. |
“High” and “Epic” are not guarantees of a particular frame rate. Your processor, graphics card, VRAM capacity, display resolution, driver state and the current game area all matter. The goal of this profile is to spend quality where it is visible and remove cost from the settings most likely to dominate GPU work.
Why Lumen and shadows should be your first cuts
Abiotic Factor runs on Unreal Engine 5. Epic’s scalability documentation notes that the number of PC hardware combinations makes one universal setting combination impossible, so performance decisions have to be measured on the machine and in the locations where you play.
#1 Best Overall
Global Illumination and Lumen
Global Illumination controls the indirect light that fills rooms and objects. In this game, that option is the practical control for Lumen’s lighting quality. Epic’s Lumen performance guidance describes the Low quality path as using only unshadowed skylight. That is why moving GI to Low is not a subtle change: interiors can look flatter and less naturally shaded, but the setting can free substantial GPU time.
Keep GI at Medium for the balanced profile. If frame time is high, test Low before changing textures. If the lighting becomes too flat, try Medium again and recover performance elsewhere, or reduce resolution scale modestly. Do not judge the change in a quiet corridor; compare a busy room with several light sources, props and shadowed surfaces.
Virtual Shadows
Virtual Shadows can be another major GPU expense. A Steam Community test reported a relative result of “Virtual Shadows – Epic 122fps -53%” against that post’s baseline. The figure describes one person’s setup and scene, not a universal 53-percent loss, but it is useful for ordering your tests: reduce Virtual Shadows before sacrificing texture resolution.
Ordinary shadow quality
If Virtual Shadows are already reduced and frame time remains high, lower the general shadow-quality control. Shadows affect the number, resolution and filtering of shadow updates. Medium often retains the basic shape of lighting while avoiding the highest cost. Compare a room with multiple nearby lights, because that is where shadow settings are easiest to see and measure.

Textures: keep detail when VRAM allows
Texture quality primarily changes the resolution of surface data rather than the amount of lighting work. The available game-specific test listed “Textures – Epic 250fps -3%,” while the same post reported much larger relative costs for Lumen GI and Virtual Shadows. Treat those numbers as one setup’s measurements, but they support a sensible rule: leave textures high when your VRAM is not full.
Lower textures when you encounter signs of memory pressure, such as delayed texture loading, surfaces appearing blurry for an unusually long time, severe hitching while moving between areas, or a graphics-memory meter that is consistently at its limit. If those symptoms do not occur, dropping from High or Epic textures may make the game look worse without addressing the actual GPU bottleneck.
Resolution scale and upscaling: the widest lever
Resolution scale changes the number of pixels the GPU must shade, so it can help when several different effects are collectively too expensive. It also affects the entire image, including geometry edges, lighting detail and fine texture clarity. For that reason, use it after selecting a reasonable quality profile and after testing GI and shadows.
Native resolution first
Begin at your monitor’s native resolution. This gives you a stable visual reference and avoids confusing a blurry internal render with a texture or anti-aliasing problem. If the game cannot sustain your target, lower the in-game resolution scale in a small step, play the same repeatable route, and compare frame time rather than only the highest FPS number.

When to use upscaling
If an upscaling option is available in your build, start with its quality-oriented mode. Move to a more aggressive mode only when the quality mode cannot meet your frame-rate target. Inspect thin cables, grates, distant signs and moving foliage for shimmering or softness. Upscaling is most useful when you are GPU-limited; it will not fix a processor-limited scene.
Step-by-step setup and testing
- Record a baseline. Load a save in a busy, repeatable area. Stand in the same place, look in the same direction and move through the same short route. Note the frame rate and whether motion feels smooth.
- Set the display foundation. Choose your monitor’s native resolution, select the desired display mode, disable motion blur, and set a frame-rate cap your PC can maintain during ordinary play.
- Apply the balanced values. Set textures to High or Epic if VRAM allows, view distance to High, Effects to Medium or High, Shadows to Medium or High, and Global Illumination to Medium.
- Measure the GPU. Unreal’s
stat FPScommand displays frame rate. Usestat unitto separate game, draw and GPU timing. If the GPU time is the largest figure, graphics settings are the right place to work; if game time is larger, lowering resolution may do little. - Change one control. Reduce Global Illumination first and repeat the same route. If the result is insufficient, restore it or keep the change deliberately, then test Virtual Shadows, general Shadows, Effects and finally resolution scale or upscaling.
- Check image quality. Look at dark corners, light transitions, moving shadows, distant geometry and fine surface detail. A higher average FPS is not automatically better if stutter or distracting artifacts appear.
- Set the cap last. Once the demanding area is stable, cap the frame rate at a sustainable value. A cap prevents the GPU from rendering unnecessary peaks and makes frame pacing easier to judge.
Run each comparison long enough to include the same doors, lights, enemies and moving through the same corridor. A single turn of the camera can change the workload, so avoid comparing unrelated scenes.

Use frame-time evidence, not a single FPS reading
FPS is an inverse measure of frame time: small timing changes can look large at high frame rates, and a brief hitch may be hidden by an average. stat unit helps identify whether the game thread, draw thread or GPU is limiting the frame. When GPU time is clearly dominant, start with Lumen and shadows. When game-thread time is dominant, reducing visual resolution may not solve the problem; close background applications, check for simulation-heavy scenes and use a sensible cap instead.
Epic’s documentation recommends measurement because PC combinations vary too widely for a universal preset. Do not treat the Steam Community figures as a benchmark promise. They establish a likely cost order for testing, not an FPS guarantee for your GPU, resolution or location.

Profiles for common situations
GPU-limited at native resolution
- Keep textures High or Epic if VRAM is healthy.
- Set Global Illumination to Low or Medium, depending on how much lighting fidelity you can accept.
- Reduce Virtual Shadows, then general Shadows.
- Lower Effects next.
- Use a quality-oriented upscaling mode or a modest resolution-scale reduction if the frame rate still misses the target.
High-VRAM system with enough GPU headroom
- Use Epic textures and High view distance.
- Keep GI at Medium or raise it only after testing the busiest areas.
- Use High shadows when frame time remains stable.
- Watch actual frame time rather than assuming high VRAM makes every setting free; VRAM capacity does not remove shader and lighting work.
Chasing a high-refresh target
- Choose a frame-rate target your system can sustain, not merely the refresh rate printed on the monitor.
- Prioritize stable frame pacing over Epic lighting.
- Reduce GI and Virtual Shadows before textures.
- Use upscaling when you are demonstrably GPU-limited, then cap below the frequent dips.
Image quality first
- Keep native resolution and high textures.
- Use Medium GI rather than Low if the flatter Low-lighting path is distracting.
- Reduce Virtual Shadows or Effects before lowering the internal resolution.
- Accept a lower frame-rate cap if that is preferable to a softer image.
Hardware expectations
Steam’s 2025 store listing identifies a GeForce RTX 3070 or AMD Radeon RX 6700 XT (or better) as recommended graphics hardware and states that Abiotic Factor runs on Unreal Engine 5. That recommendation is a hardware baseline for the game’s intended experience, not a promise of a particular FPS, resolution or Lumen setting.
| Question | What is established | How to use it |
|---|---|---|
| Recommended GPU class | GeForce RTX 3070 or Radeon RX 6700 XT or better, according to the 2025 Steam listing | Use this as a rough reference when planning native-resolution play with higher lighting settings; actual results depend on the rest of the system and the scene. |
| Engine | Unreal Engine 5 | Expect Lumen, virtualized shadow and scalability controls to influence GPU frame time. |
| Universal best settings | Not established; Epic says PC combinations are too numerous for one combination | Measure with stat FPS and stat unit on your own system. |
| Exact FPS from the recommended GPU | Not stated | Set a sustainable cap after testing your chosen resolution and location. |
A faster graphics card can make higher resolution or lighting settings practical, but no hardware recommendation here should be read as a guaranteed frame-rate result.

Unofficial Engine.ini-style overrides
Advanced users have experimented with direct configuration changes. A community guide dated June 15, 2026 gives this path:
AppData/Local/AbioticFactor/Saved/config/Windows/Settings.iniIt instructs users to add the following lines:
r.SkylightIntensityMultiplier=.15
r.Lumen.DiffuseIndirect.Allow=0
r.AmbientOcclusionMaxQuality=-100
r.AmbientOcclusionLevels=3These are unofficial overrides, not supported graphics-menu presets. They can change brightness, ambient shading and the intended look. Make a copy of the file before editing it so you can restore the original values.
How to test the overrides safely
- Exit the game completely.
- Copy
Settings.inito a safe backup location. - Open the original file in a plain-text editor and place the four lines at the bottom.
- Save without changing the file extension.
- Launch the game and compare the same test route used for the in-game settings.
- Check dark rooms and bright light sources for unwanted changes, not only the FPS counter.
The guide warns that changing Global Illumination in-game re-enables Lumen and that you may have to move the lines back to the bottom of the file. Revisit the file after patches, because updates or a settings change can undo the override. If the game looks wrong or behaves unpredictably, close it and restore the backup rather than stacking more commands.

“I lowered resolution but FPS barely changed.”
Use stat unit. If the game or draw thread is the limiting time, the workload is not primarily pixel shading. Restore a clear image, keep a sensible cap and investigate the scene or background load instead of continually lowering resolution.
“The game is smooth in a room but slow in busy areas.”
Use the busy area as your tuning reference. Reduce GI, Virtual Shadows and Shadows there, because lighting and shadow workloads vary with the number of lights, objects and visible surfaces. A quiet corridor is not a reliable benchmark for the entire game.
“The image became flat after lowering GI.”
This is expected at Low: Epic documents that the Low Lumen quality path uses only unshadowed skylight. Return to Medium if the lighting loss is unacceptable, then recover performance with Virtual Shadows, general Shadows, Effects or a modest resolution-scale change.
“Textures look blurry even though texture quality is high.”
Check VRAM pressure and streaming behavior before lowering other settings. If graphics memory is full, reduce textures one step and retest. If VRAM is not full, lowering textures may not address the cause; inspect resolution scale, upscaling and frame-time data instead.

A repeatable decision order
- Confirm the monitor’s native resolution and disable motion blur.
- Choose High textures, High view distance, Medium or High Effects, Medium or High Shadows and Medium Global Illumination.
- Use
stat FPSandstat unitin a repeatable busy area. - If GPU time is high, lower Global Illumination.
- Test Virtual Shadows, then general Shadows.
- Lower Effects.
- Only then reduce resolution scale or enable a quality-oriented upscaler.
- Lower textures when VRAM is actually the constraint, not as a first response to every hitch.
- Set a sustainable frame-rate cap and leave unofficial file edits for last.
This order protects the settings that preserve surface detail while targeting the lighting and shadow systems most likely to consume GPU time. It also keeps each change reversible, so you can stop as soon as the game meets your own frame-rate and image-quality target.
