Pacific Drive: Optimizing Engine.ini for Survival Anomalies

The primary goal for Pacific Drive optimization is Anomaly Visibility and Frame Consistency. The game’s “Volumetric Fog” is tied to its atmosphere, but it often obscures critical hazards like “Abductors” or “Tourist” clusters. Additionally, the game has a known issue with on-demand shader compilation. By pre-caching these via the config and forcing Cascaded Shadow Maps (CSM), we can achieve a stable image without the “muddy” shadows typical of the Medium setting.

Hardware Compatibility & Expectations

• UE4 Shader Stutter: Pacific Drive compiles shaders as you encounter new anomalies or storms. The tweaks below help cache these permanently.
• Garage Performance: The Auto Shop is notoriously unoptimized. You can expect a 15–20% FPS boost in the garage by disabling “Mirror Reflections” and tweaking shadow cascades.
• DX11 vs DX12: For most users, DX12 provides better stability with these INI tweaks, as it handles modern lighting calls more efficiently.

Backup and Preparation

1. Completely exit Pacific Drive.
2. Navigate to your local configuration folder (path below).
3. Copy Engine.ini and save a backup as Engine.ini.bak.
4. Open the original with Notepad++.

File Location

The configuration file is located under the game’s project name, “PenDriverPro”: %LOCALAPPDATA%\PenDriverPro\Saved\Config\WindowsNoEditor\Engine.ini

Best Engine.ini Settings for Survival Clarity

Add the following blocks to the bottom of the file. These settings specifically target the “blurry” fog and the “stuttering” shader pipeline:

[/Script/Engine.RendererSettings]
r.Shadow.CSM.MaxCascades=4
r.Streaming.FullyLoadUsedTextures=1
r.Streaming.PoolSize=4096      ; Set to 50% of your VRAM
r.Fog=0                        ; Removes the dense "distance fog" for clarity
r.VolumetricFog=0              ; Disables the heavy atmospheric light scattering

[SystemSettings]
r.MotionBlurQuality=0
r.DefaultFeature.MotionBlur=0
r.DepthOfFieldQuality=0
r.SceneColorFringeQuality=0    ; Removes Chromatic Aberration
r.Tonemapper.GrainQuantization=0
r.Shadow.DistanceScale=1.5     ; Keeps shadow quality high at a distance

Pro Tip: If the game feels too dark after disabling fog, keep r.Fog=1 but set r.VolumetricFog=0. This retains the “moody” horizon while removing the thick haze that makes it hard to see hazards directly in front of your station wagon.

Key Parameters Explained

Parameter	Recommended Value	Impact
r.Shadow.CSM.MaxCascades	4	Restores sharp shadows on Medium settings, fixing the “pixelated” ground look.
r.Streaming.FullyLoadUsedTextures	1	Forces the game to load textures into VRAM instantly, preventing the “blurry sign” bug.
r.VolumetricFog	0	The single biggest visibility and FPS boost in the Exclusion Zone.
r.SceneColorFringeQuality	0	Removes the “rainbow blur” at the edges of the screen, reducing eye strain.

In-Game Graphics Strategy (Settings Menu)

To ensure the Engine.ini edits provide the best result, match these in-game settings:

• Shadow Quality: Set to High. If you use the CSM tweak above, you can drop this to Medium for more FPS without losing the sharp shadow detail.
• Mirror Quality: Set to Low. You rarely use the side mirrors for precision, and they render the world a second time, which is a massive performance drain.
• AA Method: Set to TSR (Temporal Super Resolution) if on DX12. It provides much better stability than standard TAA in the rain.

Troubleshooting & Common Fixes

• Micro-Stutters: If the game hitches when you enter a new zone, ensure you have deleted the USHADERPRECACHE files in the Saved folder after applying these tweaks. This forces a clean re-compile.
• Lights Too Bright: Disabling volumetric fog can make headlights look a bit “flat.” If you miss the beam effect, re-enable r.VolumetricFog=1.
• Settings Resetting: Ironwood Studios updates the game frequently. After saving your changes, right-click Engine.ini > Properties > Check Read-only.

Frequently Asked Questions (FAQ)

Conclusion and Expected Results

By manually refining your Engine.ini, you are clearing the atmospheric clutter that limits your ability to navigate the Zone. You can expect a significant increase in visual range, the elimination of texture-pop in, and a much smoother frame-time graph during storms.
