How To Fix Packet Burst BO7

“Packet Burst” (those three annoying orange squares on the left of your screen) is a widespread issue in Call of Duty: Black Ops 6 (BO6). This error usually means your CPU or VRAM is choking on data, rather than your internet being “slow.”

Here is the step-by-step guide to fixing it, ranked from the most effective “Golden Fix” to standard network troubleshooting.

1. The “Golden Fix” (Texture Streaming)

The #1 cause of packet burst in BO6 is the “On-Demand Texture Streaming” setting. It forces your game to constantly download high-quality textures while you play, clogging your connection and CPU.

• Go to Settings > Graphics > Quality.

• Scroll to “On-Demand Texture Streaming”.

• Do NOT just turn it off (sometimes it forces itself back on). Instead:

  1. Set it to “Minimal”.

  2. Expand the “Show More” menu.

  3. Set “Texture Cache Size” to Small (or Limited).

  4. Enable “Download Limit” and set it to something very low (like 1.0 GB) to stop it from hogging bandwidth.

2. The VRAM Target Fix (PC Only)

If your VRAM is maxed out, the game stutters and throws a packet burst error because it can’t process data fast enough.

• Go to Settings > Graphics > Quality.

• Find “VRAM Scale Target”.

• Lower this from the default (usually 80-90) down to 60% or 70%.

  • Why? This leaves “breathing room” for background apps (like Discord or Windows tasks) so they don’t fight the game for memory.

3. The Config File Edit (Advanced PC Fix)

If the in-game settings don’t stick, you can force the render worker count to match your CPU cores.

1. Close the game.

2. Go to Documents \ Call of Duty \ players.

3. Look for a file named options.4.cod24.cst (the number 24 might vary, look for the most recently modified “options” file).

4. Open it with Notepad.

5. Press Ctrl + F and search for RendererWorkerCount.

6. Change the number inside the value to match your CPU’s physical cores (not threads).

   • Example: If you have an Intel i7-12700K (12 cores), try setting it to 11 or 12. If you are unsure, setting it to 4 or 6 is often a safe “stability” number for most gaming CPUs.

7. Save the file and restart the game.

4. Network & Router Settings

If the above are hardware-related fixes, these are the connection-related ones:

• Disable Crossplay (Console Only): On PS5 or Xbox, go to Account & Network settings and turn off Crossplay. This forces the game to find local servers, which can sometimes reduce packet issues (though it increases matchmaking time).

• Port Forwarding: Packet burst often happens when your router’s “NAT Type” is Strict or Moderate. Forwarding port 3074 (UDP/TCP) for your specific platform is the standard fix.

• Ethernet is King: If you are on Wi-Fi, you will almost always get packet burst in COD titles due to signal interference.Use a cable if possible.

Summary Checklist

• Set Texture Streaming to Minimal.

• Lower VRAM Scale Target to 70%.

• Turn off “Eco Mode” in graphics settings (set to Efficiency or Low Power often causes lag).

• (PC) Update DLSS/FSR settings to “Performance” to reduce GPU strain.
