Fix Night City: Config Overhaul for Cyberpunk 2077 Guide Cyberpunk 2077 is a visual masterpiece, but it is notoriously brutal on PC hardware. High-end rigs often choke in crowded areas like Kabuki, while mid-range systems struggle to maintain a stable 60 FPS. While the in-game settings menu offers decent control, the real performance bottlenecks lie deeper inside the game’s hidden configuration files.
By modifying these underlying files, you can optimize engine behavior, eliminate micro-stuttering, fix aggressive crowd pop-in, and unlock hidden frames without sacrificing visual quality. This guide will walk you through the essential config overhauls to finally make Night City run smoothly. 1. Optimize the Engine Config (Hidden Memory Pool Fix)
Cyberpunk 2077 utilizes an internal configuration file to allocate system RAM and Video RAM (VRAM). Sometimes, the engine misjudges your PC configuration, leading to unnecessary asset streaming and aggressive stuttering. Navigate to your Cyberpunk 2077 installation folder. Go to \engine\config\platform\pc</code>.
Locate the file named pc.ini. (If it does not exist, you can create it using Notepad, or look for platformconfig.ini depending on your game patch version).
Open the file with a text editor and add or modify the following lines to maximize asset caching:
[ResourceLoaderThrottler] FloodMinRemainingTime = 0.010000 StreamMinRemainingTime = 0.020000 Use code with caution.
What this does: This tweak forces the engine to stream textures and world assets more aggressively into your available memory, reducing the sudden frame drops that occur when you drive fast through the city. 2. Tweak the Cyber Engine Tweaks (CET) Config
For absolute control over the game engine, installing the Cyber Engine Tweaks (CET) mod via Nexus Mods is highly recommended. It unlocks a console and patches core engine bugs at startup. Once installed, press the tilde key (~) to open the CET overlay and adjust these settings:
Asynchronous Compute: Keep this enabled if you are running a modern DirectX 12 graphics card (Nvidia RTX or AMD RX series). It allows your GPU to execute multiple tasks simultaneously.
Memory Pool Overrides: If CET prompts memory configuration options, ensure your pool sizes match your hardware specs. Set your RAM pool to half of your total system RAM, and your VRAM pool to your GPU’s maximum capacity minus 1 GB (for Windows overhead). 3. Advanced Input & Camera Fixes via Config
If you suffer from floaty mouse movement, sudden camera acceleration, or clunky driving controls, the issue lies within the game’s input configuration.
Navigate to %USERPROFILE%\AppData\Local\CD Projekt Red\Cyberpunk 2077</code>. Open UserSettings.json using Notepad. Search for “padDeadzone” or “mouseSensitivity” variables.
To completely eliminate forced mouse smoothing and acceleration, look for the input curves and set the response factor to a flat, linear scale: “value”: 0.0, “is_default”: false Use code with caution.
What this does: This decouples your camera movement from post-processing filters, giving you raw mouse input for sharper aiming and more responsive vehicle handling. 4. The Hidden In-Game Menu Configs to Change
Config files lay the groundwork, but three specific in-game configurations heavily impact how those files behave. Ensure these are set correctly to match your new overhaul:
Crowd Density (Gameplay Menu): Set this to Medium. “High” overloads your CPU with entity paths, causing massive framerate dips regardless of your graphics card.
HDD Mode (Gameplay Menu): Set to On only if the game is installed on a mechanical hard drive. If you are on an NVMe or SATA SSD, keep this strictly Off to allow your config file tweaks to stream assets properly.
Cascaded Shadows Resolution (Graphics Menu): Lower this from High to Medium. This single setting frees up immense VRAM and aligns perfectly with the engine optimizations made in your .ini files. 5. Locking in Your Changes
Windows will occasionally overwrite modified configuration files during official game patches or Steam/GOG file verifications.
To prevent your hard work from being wiped out, right-click on the modified .ini files (like pc.ini), select Properties, check the Read-only box, and hit Apply. If you ever need to change your settings in the future, just uncheck the box, edit the file, and lock it back down.
With these hidden engine constraints removed, Cyberpunk 2077 will better utilize your actual hardware components. Enjoy a smoother, stutter-free trek through the neon-soaked streets of Night City.
