The primary goal for Dredge optimization is Visibility Balance. The game uses a custom lighting system to handle the day-to-day transition and the “Panic” mechanics. This configuration focuses on increasing the draw distance of light sources (like your boat’s lamp) and stabilizing the volumetric fog so it remains atmospheric without becoming a “wall of gray” that kills your frame rate.
Hardware Compatibility & Expectations
- Volumetric Fog: This is a GPU-intensive setting. If you are on an integrated GPU or Steam Deck, lowering the fog resolution in the config is the best way to gain 10–15 FPS.
- Lighting Interaction: Every light source in Dredge (buoys, lighthouses, your boat) casts dynamic shadows. Reducing the shadow resolution slightly can help keep frame-times flat during the Night cycle.
- 4K Clarity: At 4K, the game’s “Film Grain” can look a bit noisy. We will adjust the post-processing flags to keep the image clean.
File Location
Dredge is built on the Unity engine, and its configuration files are stored in the local AppData directory:
%USERPROFILE%\AppData\LocalLow\Black Salt Games\Dredge\settings.json
Technical Configuration (Code Block)
Open the settings.json with a text editor. Modify these specific parameters to fine-tune the lighting and fog systems:
{
"graphics": {
"resolutionWidth": 1920,
"resolutionHeight": 1080,
"fullscreenMode": 1, // 1 = Exclusive Fullscreen
"vSync": 0, // 0 = Off; essential for smooth boat handling
"qualityLevel": 3, // 3 = Ultra
"fogQuality": 1, // 0 = Low, 1 = Med, 2 = High (Med is best for clarity)
"shadowQuality": 2, // 2 = High; ensures sharp silhouettes of monsters
"bloomEnabled": false, // Disabling bloom reduces fog "glow" for better sight
"filmGrainEnabled": true, // Keep true for atmosphere, or false for raw pixels
"chromaticAberration": false // Disabling this makes the edges of the screen sharper
},
"gameplay": {
"cameraShakeIntensity": 0.5, // Lowering this helps with motion sickness in storms
"heldInputTime": 0.2
}
}
Strategy for Fog and Lighting
To navigate the murky waters of the Marrows effectively:
- The Fog Quality Sweet Spot: Setting
fogQualityto 1 (Medium) is actually superior to High for gameplay. It maintains the volumetric look but reduces the “density” of the light-scattering, allowing you to see red-glowing eyes and distant buoys more clearly. - Disable Bloom for Night Vision: When your boat’s lamp is on,
Bloomcreates a halo effect around the light that actually reflects off the fog, making it harder to see what’s in front of you. Turning it off removes this “white-out” effect. - Chromatic Aberration: During high “Panic” levels, the game distorts the screen. If this makes you feel nauseous or makes it too hard to pilot the boat, setting
chromaticAberrationtofalsein the JSON will keep the image stable even when your character is losing their mind.
Key Performance Parameters
| Parameter | Recommended Value | Impact |
| fogQuality | 1 (Medium) | Best balance between atmosphere and navigation visibility. |
| bloomEnabled | false | Prevents the boat’s lamp from “blinding” the player in thick fog. |
| vSync | 0 (Off) | Reduces the input lag of the boat’s steering and fishing mini-games. |
| shadowQuality | 2 | Crucial for spotting the silhouettes of hostile sea creatures early. |
Frequently Asked Questions (FAQ)
Does turning off fog give me an unfair advantage?
In Dredge, the fog is part of the “Panic” mechanic. While these settings make the fog clearer, they do not remove the mechanic itself. You will still face the dangers of the night, but your hardware won’t struggle to render it.
Why is my frame rate dropping at Sunset?
Sunset triggers the “Long Shadows” and “Atmospheric Scattering” effects. If your FPS drops here, lower the shadowQuality to 1 in the settings.json.
How do I fix the “stuttering” during fast travel or sailing?v
Dredge streams island assets as you move. Ensure the game is installed on an SSD and that fullscreenMode is set to 1 (Exclusive) to prioritize the GPU render thread.
Can I change the color of the lighting?
Not directly in the JSON. The game’s color palette is tied to the “Panic” level and the specific biome you are in (e.g., the red glow of the Devil’s Spine vs. the green of the Gale Cliffs).
Conclusion and Expected Results
By manually refining your settings.json to prioritize volumetric clarity and disabling bloom-based glare, you are optimizing Dredge for both performance and survival. You can expect easier navigation through the night, more responsive boat controls, and a hauntingly beautiful atmosphere that doesn’t compromise your visibility.
