Overview
inZOI runs on Unreal Engine 5 with advanced rendering technologies including Lumen global illumination, Nanite virtualized geometry, and Virtual Shadow Maps. These features produce photorealistic visuals but place heavy demands on hardware. This guide covers every graphics setting, upscaling technology, and system-level optimization to help you find the right balance between visual quality and frame rate. For minimum and recommended hardware, see the System Requirements article.
Graphics Presets Overview
inZOI offers five built-in presets. The game also includes an Auto Select button that detects your hardware and picks a starting preset. The table below shows approximate frame rates at 4K resolution with DLSS Quality upscaling on an RTX 4080.
Preset | Approximate FPS (4K, DLSS Quality) | Notes |
|---|---|---|
Very Low | ~135 FPS | Significant visual reduction; good for low-end hardware |
Low | ~115 FPS | Reduced textures and effects; noticeable quality drop |
Medium | ~107 FPS | Balanced option for mid-range GPUs |
High | ~86 FPS | Recommended starting point for most players |
Ultra | ~73 FPS | Near-maximum quality; diminishing returns vs High |
Ultra + Ray Tracing | ~68 FPS | Heaviest option; hardware ray tracing enabled |
Starting from the High preset and switching to Custom mode to adjust individual settings gives the best results for most systems.
Individual Graphics Settings
After selecting a preset, switch to Custom to fine-tune. The settings below are listed in order of performance impact, from most to least significant.
High-Impact Settings
Setting | What It Does | Recommendation |
|---|---|---|
DLSS / FSR / XeSS | AI-based upscaling that renders at a lower internal resolution and reconstructs the image. The single biggest performance lever in the game. | Quality mode for sharp visuals with a large FPS boost. Performance or Ultra Performance for struggling hardware. |
Ray Tracing | Enables hardware ray tracing for global illumination, reflections, and shadows. Costs 6-8% FPS over stock Lumen lighting. Very Low RT looks worse than stock Lumen. | Off for maximum performance. High if your GPU handles it comfortably. Avoid Very Low. |
Ray Tracing Quality | Controls the precision of ray traced effects when Ray Tracing is enabled. | High if RT is on. Ultra provides minimal visible improvement over High. |
Shadow Quality | Resolution and precision of dynamic shadows. One of the most impactful settings. Reducing from Ultra to Medium provides roughly a 10% frame rate boost. | High. Ultra has barely noticeable improvement. |
Global Illumination Quality | Controls Lumen's indirect lighting accuracy. Switching from Ultra to Medium can grant approximately a 20% FPS improvement. | High for good visual fidelity. Medium if chasing frames. |
Reflection Quality | Detail level of screen-space and Lumen reflections on surfaces. | High. Lower to Medium on mid-range GPUs. |
Medium-Impact Settings
Setting | What It Does | Recommendation |
|---|---|---|
Post-Processing Quality | Volumetric lighting, fog, screen-space effects, and color grading. Ultra costs 5-15% performance over High with subtle differences. | High. The visual difference from Ultra is minimal. |
Shader Quality | Controls surface shader complexity including parallax mapping, normal maps, blending, and tessellation (called Material Detail in some menus). | High. Reducing to Medium gives a noticeable FPS bump. |
Anti-Aliasing Quality | inZOI applies a temporal anti-aliasing (TAA) filter on top of DLSS/FSR. Controls the quality of edge smoothing. | High with DLSS. Medium without upscaling. |
Background Detail Quality | Draw distance and level of detail for distant buildings and terrain. | High. Reducing this can improve FPS in dense city areas. |
Realistic Shadows | Additional shadow detail for environmental lighting. Disabling provides 4-8% GPU headroom. | Off for performance. On for visual fidelity. |
Shadow-Casting Lighting Effect | Whether individual light sources (streetlamps, etc.) cast dynamic shadows. | Off for performance. On for realism. |
Low-Impact Settings
Setting | What It Does | Recommendation |
|---|---|---|
Texture Quality | Resolution of surface textures. Primarily limited by VRAM rather than GPU performance. Uses up to 10 GB VRAM at Ultra with 4K and ray tracing. | Ultra if you have 8 GB+ VRAM. High with 6 GB. |
Effects Quality | Detail of particle effects including smoke, fog, smog, color effects, and emissives. | High. Rarely a bottleneck. |
Face and Hair | Quality of subsurface scattering for character skin and hair rendering. | High or Ultra. Affects character close-ups. |
Plant Density and Quality | Vegetation quality, density, and draw distance. Note: this setting has minimal effect in the current Early Access build. | High. Currently does not significantly impact visuals or performance. |
Character / Object / Lighting Display Distance | How far away characters, objects, and light sources render at full detail. | High. Ultra adds minimal visible benefit. |
Occlusion Method | How the game determines which objects are hidden behind others. Options: Hardware, Depth Information, or Off. | Off if using Ray Tracing. Depth Information otherwise. |
Display Settings
Setting | Recommendation | Notes |
|---|---|---|
Display Mode | Fullscreen | Best performance. Windowed modes add overhead. |
Resolution | Native monitor resolution | Lower only as a last resort. |
Resolution Scale | 100% | Reducing below 100% causes blurriness. Use DLSS/FSR instead. |
Dynamic Resolution | Off (or On for struggling hardware) | Automatically lowers resolution to maintain a target FPS. |
Maximum FPS | Match your monitor refresh rate, or cap at 100 | Capping FPS reduces temperature spikes and improves frame pacing. |
Vertical Sync | Off (use in-game FPS cap instead) | VSync adds input latency. Disable if your monitor supports variable refresh rate (G-Sync/FreeSync). |
Motion Blur | Off | Reduces clarity without improving performance. Recommended off. |
Depth of Field | Personal preference | No significant performance cost. |
Upscaling Technologies
Upscaling renders the game at a lower internal resolution and uses AI or algorithmic reconstruction to output a higher-resolution image. This is the most effective way to gain performance in inZOI without major visual loss.
NVIDIA DLSS
inZOI supports DLSS 3.5 with Super Resolution and Frame Generation on RTX 20, 30, and 40 series GPUs. DLSS 4 with Multi Frame Generation for RTX 50 series is planned for August 2026.
DLSS Mode | Internal Resolution (at 4K output) | Use Case |
|---|---|---|
DLAA | Native (3840x2160) | Best anti-aliasing quality. No upscaling. GPU-intensive. |
Quality | 2560x1440 internal | Recommended for most players. Nearly identical to native at 1440p+. |
Balanced | 2227x1253 internal | Good balance on mid-range GPUs. |
Performance | 1920x1080 internal | Significant FPS boost. Minor softness visible up close. |
Ultra Performance | 1280x720 internal | Maximum FPS gain. Noticeable quality reduction. Last resort. |
DLSS Frame Generation is available on RTX 40 and 50 series GPUs. It generates intermediate frames between real rendered frames, providing roughly a 60% performance boost. Frame Generation works best when your base FPS is below 70. Above 80-90 FPS, disable it to avoid potential instability.
To enable DLSS Frame Generation: go to Windows Settings, then System, then Display, then Graphics Settings, and enable Hardware-accelerated GPU scheduling. Restart your computer before activating Frame Generation in the game settings.
AMD FSR
FSR 3 upscaling and frame generation can be enabled by editing the GameUserSettings.ini file located at: AppData\Local\BlueClient\Saved\Config\Windows\GameUserSettings.ini
INI Setting | Value | Effect |
|---|---|---|
FSR3Value | 2 | Performance mode |
FSR3Value | 3 | Balanced mode |
FSR3Value | 4 | Quality mode |
FSR3Value | 5 | Native AA (highest quality) |
FSR3FI | True | Enables FSR 3 Frame Generation |
Players report a 20+ FPS increase on minimum-spec systems when combining FSR upscaling with frame generation. FSR does not require specific GPU hardware and works on both NVIDIA and AMD cards.
Intel XeSS
XeSS (Xe Super Sampling) is available for Intel Arc GPUs. It functions similarly to DLSS and FSR, with Quality, Balanced, Performance, and Ultra Performance modes. XeSS also works on non-Intel GPUs as a fallback upscaler.
Simulation and Gameplay Settings
These settings are separate from graphics but can affect performance, especially on CPU-limited systems.
Setting | Recommendation | Notes |
|---|---|---|
Animation Quality | 3ms | Controls how much CPU time is spent on character animations. Setting higher than 3ms is not noticeable but wastes CPU resources. |
Outfit Simulation | On | Fabric physics for clothing. Minimal performance cost. |
Applied Range in City | Reduce if CPU-limited | Controls how many Zois in the city are fully simulated. "Small Group of Zois on Screen" reduces CPU load. |
Queue Limit | 8 | Maximum number of queued actions per Zoi. Lower values reduce memory usage slightly. |
System-Level Optimizations
Windows Settings
Power Plan: Set Windows to High Performance mode. Open Control Panel, then Hardware and Sound, then Power Options, and select High Performance.
Hardware-Accelerated GPU Scheduling: Enable in Windows Settings under System, then Display, then Graphics Settings. Required for DLSS Frame Generation and generally improves GPU task management.
Memory Integrity: Disabling Memory Integrity (Virtualization-Based Security) in Windows Security settings can improve FPS in some configurations.
Background Applications: Close unnecessary programs, browser tabs, and system tray applications before playing. Each background app consumes RAM and CPU cycles.
Virtual Memory: If you experience crashes or stuttering with 16 GB RAM, increase the Windows page file size. inZOI can use significant system memory during extended play sessions.
NVIDIA Driver and Control Panel
RTX 50 Series: Use driver 572.83 or newer.
RTX 40 Series: Driver 566.36 is recommended. Some players report frame drops with 572.xx drivers on 40-series cards.
RTX 30 Series and older: Use the latest available driver.
In the NVIDIA Control Panel under Program Settings for inzoi.exe, set Power Management Mode to Prefer Maximum Performance, Shader Cache to On, and Texture Filtering to High Performance.
Storage
Installing inZOI on an SSD (ideally NVMe) significantly reduces texture streaming stutters and load times. Unreal Engine 5 relies heavily on streaming assets from disk, so mechanical hard drives can cause noticeable hitching during gameplay.
Engine Configuration Tweaks
Advanced users can place a custom Engine.ini file at AppData\Local\BlueClient\Saved\Config\Windows\Engine.ini to fine-tune Unreal Engine 5 parameters. Several community-made configuration files are available on NexusMods that optimize CPU and GPU multi-core rendering, shader compilation, and asset streaming. After placing an Engine.ini file, set it to Read-only in the file properties so the game does not overwrite it.
Popular optimization mods on NexusMods include the InZOI Optimizer (reduces stuttering through asset and shader optimization) and various Engine.ini tweaks that target multi-core rendering and shader compilation. See the Modding Getting Started Guide for instructions on installing NexusMods content.

Troubleshooting
Problem | Solution |
|---|---|
Stuttering during gameplay | Install on SSD. Enable Shader Cache in NVIDIA Control Panel. Try an Engine.ini optimization mod. Increase Windows page file if RAM is at 16 GB. |
Low FPS despite good hardware | Check that the game is using the correct GPU (not integrated graphics). Set Windows Power Plan to High Performance. Update GPU drivers. Close background applications. |
Frame Generation not working | Enable Hardware-accelerated GPU scheduling in Windows. Restart your computer. Disable NVIDIA overlay and screen capture apps. Use Fullscreen display mode. |
VRAM usage too high | Lower Texture Quality from Ultra to High. Disable Ray Tracing. Reduce Resolution Scale if above 100%. |
Crashes after extended play | Increase Windows page file. Monitor RAM usage. Disable Ray Tracing if unstable. Verify game files through Steam. |
Ray Tracing artifacts | Update GPU drivers. Switch Ray Tracing Object from Actual Mesh to Fallback Mesh if visual glitches appear. Disable RT at Very Low as it looks worse than stock Lumen. |
Tips
Stable frame times matter more than peak frame rates. Capping at 100 FPS with consistent delivery feels smoother than fluctuating between 80 and 140.
DLSS Quality mode is the single best performance upgrade for NVIDIA users. It nearly matches native resolution quality while rendering at a lower internal resolution.
Avoid setting Resolution Scale below 100%. Use DLSS, FSR, or XeSS instead for a much cleaner result.
Shadow Quality and Global Illumination are the two settings where lowering from Ultra to High gives the biggest FPS return for the smallest visual loss.
RAM usage of 70-85% is normal for inZOI due to Unreal Engine 5's asset caching. This only becomes a problem if you experience freezing or constant stuttering.
After any game update, check that your graphics settings have not been reset to defaults. Major patches occasionally overwrite custom configurations.
