InZOI Performance Summary

Occlusion: Change this to "Off" if you're using ray tracing. Otherwise, set it to "Depth Information."

Fallback Mesh: Enable if the above doesn't help with ray tracing performance.

Shadow Quality: Reduce it to Medium for a 10% frame rate boost with minimal quality reduction.

Global Illumination: Switch to Medium for DFAO, granting a ~20% FPS bump.

Lumen GI

Lumen GI remains quite expensive despite its promises, draining performance by up to 20% at the highest-quality option:

- Ultra: ~20% slower than the lowest quality. It features higher GI resolution, coverage, and distance. Light bleeding is also more accurate.
- High: Reduces the resolution and draw distance of GI. Light bleeding is less accurate. Roughly 11% slower.
- Medium/Low: Falls back to a mix of distance-field ambient occlusion (large scale) and screen space ambient occlusion (small scale). No notable performance hit, but also no actual GI and limited AO coverage.
- Very Low: Disables everything.

Shadow Quality

InZOI leverages Virtual Shadows that are quite taxing at higher quality settings. The resulting contact-hardened shadows are visually appealing but suffer from noisy penumbras:

- Ultra & High: Perform about the same, with ~15% performance loss.
- Medium: Reduces penumbra quality and shadow LOD (~10%).
- Low: Disables Virtual Shadows, replacing them with blocky proxies (~8%).
- Very Low: Disables all shadows.

Enabling FSR 3 Upscaling and Frame Generation

You can enable FSR 3 by tweaking the "GameUserSettings.ini" in the following directory:

C:\Users\USERNAME\AppData\Local\BlueClient\Saved\Config\Windows

Under `[ /Script/BlueClient.B1GameUserSettings ]`, edit these values:

- `FSR3Value=X`
- Set X to:
- 2 for Performance
- 3 for Balanced
- 4 for Quality
- 5 for Native AA

- `FSR3FI=True`
- Enables FSR 3 Frame Generation.

InZOI: VRAM Usage

InZOI uses up to 10 GB of VRAM at 4K using the maximum quality settings, including ray tracing. Lower resolutions like 1440p and 1080p reduce it to around 9 GB.
