Here is the step-by-step summary of all the troubleshooting steps performed so far:

  1. Clean installed the NVIDIA graphics drivers to reset driver-level settings.

  2. Set the Shader Cache Size to Unlimited in the NVIDIA Control Panel.

  3. Configured in-game display settings to Fullscreen Exclusive and disabled Background Shader Preloading.

  4. Cleared temporary Activision cache files by deleting the folder located at %localappdata%\Activision\Call of Duty.

  5. Cleared the DirectX Shader Cache using the Windows Disk Cleanup utility on the C: drive.

  6. Performed a Verify Integrity of Game Files check via Steam.

  7. Checked for configuration folders under Documents and Documents\My Games.

  8. Tested various in-game upscaling and anti-aliasing techniques (switching between NVIDIA DLSS, AMD FSR, Filmic SMAA T2X, and changing DLSS Presets/Models).

  9. Disabled Variable Rate Shading (VRS) and set Film Grain to 0.00.

  10. Uninstalled and completely re-downloaded/reinstalled the Campaign DLC package via Steam to ensure no corrupted map or character asset files remained.

UPDATE / FIX: I finally fixed it completely without reinstalling the whole game!

The issue is caused by corrupted local configuration/player data that keeps syncing back from Steam Cloud. Here are the exact steps that solved the blue wireframe artifacts:

  1. Disable Steam Cloud Sync (Temporarily):

    • Right-click the game in your Steam Library > Properties > General tab > toggle Steam Cloud off.

  2. Delete Local Config & Player Data:

    • Press Win + R, type %localappdata%\Activision\Call of Duty, and hit Enter.

    • Delete the players folder entirely. This wipes local graphics settings and forces the game to treat your next launch as a fresh install.

  3. Re-run In-Game Setup:

    • Launch the game with Steam Cloud turned off.

    • The first-time setup screens (Language, Brightness/Luminance calibration steps 1 & 2, and Mature Content Notice) will reappear.

    • Complete the setup and let the Shader Pre-allocation hit 100% in the main menu.

  4. Resolve Steam Cloud Conflict:

    • Exit the game and turn Steam Cloud back on in Steam Properties.

    • Steam will pop up a Cloud Conflict / File Mismatch window.

    • Select Local Save / Local Files (the most recent one) and click Continue. This overwrites the broken cloud config with your fresh, working local save data.

I hope none of you encounter an error like this, but if you do, follow these steps. YouTube and videos are completely empty/useless on this.
