Disable Texture Streaming & Fix Hit Reg (IP Block List + Script)
Hey everyone,
If you've been dealing with terrible hit registration, rubber-banding, or packet bursts in Black Op or Warzone, a lot of it comes down to the game's background texture streaming and connecting to sub-optimal data centers.
By completely blocking the Call of Duty CDN and specific problematic server subnets, you can force the game to run smoother, lower your ping, and make the hit reg feel like "old CoD."
Here are the two best ways to do this:
Method 1: The Windows Hosts File (Quickest for Texture Streaming)
If your main goal is simply to stop the game from downloading high-res textures in the background (which hogs bandwidth and causes micro-stutters), you can block the CDN domain directly.
Method 2: Block Server Subnets via PowerShell (Advanced)
If you want to go a step further and block the specific IP ranges associated with bad server routing and hit reg nerfs, you can add them to your Windows Defender Firewall.
Instead of blocking individual IPs (which can change dynamically), this script uses the /24 subnets to block the entire range so it continues to work even if the server machines swap.
How to apply:
How to Reverse the Firewall Changes
If you ever want to revert these changes (for example, if you are having trouble finding a match or connecting to friends), run this script in an Administrator PowerShell window to delete the rules:
Let me know if you guys notice an FPS boost or better ping after trying this!

If your main goal is simply to stop the game from downloading high-res textures in the background (which hogs bandwidth and causes micro-stutters), you can block the CDN domain directly.
- Navigate to C:\Windows\System32\drivers\etc
- Open the hosts file using Notepad (Make sure to open Notepad as Administrator first).
- Add the following line to the very bottom of the file: 127.0.0.1 cod-assets.cdn.callofduty.com
- Save the file and restart your PC.
Method 2: Block Server Subnets via PowerShell (Advanced)
If you want to go a step further and block the specific IP ranges associated with bad server routing and hit reg nerfs, you can add them to your Windows Defender Firewall.
Instead of blocking individual IPs (which can change dynamically), this script uses the /24 subnets to block the entire range so it continues to work even if the server machines swap.
How to apply:
- Open Windows PowerShell as Administrator.
- Paste the following code and hit Enter:

# Create inbound and outbound rules for each IP range

New-NetFirewallRule -DisplayName "COD Block Outbound $IP" -Direction Outbound -Action Block -RemoteAddress $IP -Profile Any -Enabled True
}
Write-Host "All specified CoD server IPs have been blocked successfully."How to Reverse the Firewall Changes
If you ever want to revert these changes (for example, if you are having trouble finding a match or connecting to friends), run this script in an Administrator PowerShell window to delete the rules:
$RulePrefix = "COD Block"
Get-NetFirewallRule | Where-Object { $_.DisplayName -like "$RulePrefix*" } | Remove-NetFirewallRule -ErrorAction SilentlyContinue
Write-Host "All specified CoD block rules have been removed."Let me know if you guys notice an FPS boost or better ping after trying this!
