Call of Duty Setup

In-Game Graphics Settings (Required)

Call of Duty must run at minimum graphics settings with FidelityFX CAS upscaling. NVIDIA DLSS and Reflex DLL hooks conflict with Reaper — do not use them.

Set all graphics to minimum

1. Launch Call of Duty → Settings → Graphics.
2. Set Display Mode to Fullscreen Exclusive (or Borderless if exclusive causes issues).
3. Set every quality option to Low or Minimum:
   • Texture Resolution → Low
   • Texture Filter Anisotropic → Low
   • Particle Quality → Low
   • Shader Quality → Low
   • Shadow Map Resolution → Low
   • Spot Cache / Spot Shadow → Low
   • Volumetric Quality → Low
   • Reflection Quality → Low
   • Anti-Aliasing → Off or lowest available
   • Ambient Occlusion → Off
   • Depth of Field → Off
   • World Motion Blur → Off
   • Weapon Motion Blur → Off

Upscaling — FidelityFX CAS, NOT NVIDIA DLSS

Critical: Do not use NVIDIA DLSS, DLSS Frame Generation, NVIDIA Reflex, or any NVIDIA upscaling DLL.

1. Find Upscaling / Sharpening in Graphics settings.
2. Set upscaling to FidelityFX CAS (AMD FidelityFX Contrast Adaptive Sharpening).
3. If FidelityFX CAS is not available, set upscaling to Off and keep all settings at minimum.

Launch Procedure

Important: Run the loader from the in-game main menu while you are on the screen showing your operator/character. Do not run it from the desktop, before launching the game, or while in a match.

1. Complete the system setup guide.
2. Launch Call of Duty and wait until you reach the main menu.
3. Navigate to the screen where your operator/character is visible.
4. Run the Reaper loader as Administrator (do not leave the main menu).
5. Enter your license key when prompted and wait for confirmation.

Troubleshooting

• Loader closes immediately — Defender still active. Re-run Sordum Defender Control.
• Loader does nothing — Make sure you are on the main menu with your operator/character visible, not on the desktop or in a match.
• Game crashes on launch — Verify minimum graphics and FidelityFX CAS (not DLSS).
• Black screen — Switch Fullscreen Exclusive ↔ Borderless.
• Anti-cheat errors — Secure Boot ON, Memory Integrity OFF.
