Understanding Pure Servers

The error “Disconnected: Pure server: file does not match server’s file” occurs when a player’s local game files differ from the assets hosted on the server. Counter-Strike 2 defaults to strict file matching to prevent client-side exploits like transparent textures or modified models.

​
Identifying the Cause

If you have installed custom player skins, weapon models, or unique map textures, the client’s game engine will detect a mismatch with the official Valve signatures. Under default settings (sv_pure 1), this results in an immediate kick from the lobby.

​
The Solution: Adjusting sv_pure

For community servers hosting modded content, you must disable strict file checking:
  1. Access your FREAKHOSTING Control Panel.
  2. Navigate to the Startup tab.
  3. Locate the Additional Arguments or sv_pure field.
  4. Set the value to +sv_pure 0.
  5. Restart the server to apply the changes.
Setting sv_pure 0 disables all client-side file verification.
  • Casual/Surf/Bhop: This is standard and required for custom content.
  • Competitive/Leagues: This is considered a security risk as it allows players to use wallhack textures (e.g., making crates or walls transparent).
