Understanding Pure Servers

The error message “Disconnected: Pure server: file [path] does not match server’s file” is a common obstacle when hosting modded content in Counter-Strike 2 (CS2). This issue occurs when a player’s local game files differ from the authoritative assets residing on the server. By default, the Source 2 engine enforces strict file matching to prevent client-side exploits, such as transparent textures or modified player models, ensuring a fair environment for competitive play.

​
Identifying the Cause

If you have implemented custom player skins, weapon models, or unique map textures on your server, the client’s engine will detect a discrepancy between their local files and the official Valve signatures. Under the default sv_pure 1 configuration, this mismatch triggers an immediate disconnection to maintain match integrity.

​
Configuring sv_pure for Custom Content

To allow players with modded assets to connect to your community server, you must adjust the engine’s verification strictness.
1

Access the Game Panel

Log in to your FREAKHOSTING Game Panel and select your CS2 server.
2

Open Startup Settings

Navigate to the Configuration menu and select the Startup tab.
3

Modify Environment Variables

Locate the field for Additional Arguments or the specific sv_pure variable.
4

Apply the Override

Set the value to 0 or add +sv_pure 0 to your startup flags.
5

Initialize Changes

Return to the Console and click Restart. The server will now allow custom file signatures.

Security & Balance Considerations

​
Competitive Integrity Risks

Disabling strict file checking (sv_pure 0) removes the primary barrier against client-side texture exploits.
  • Casual & Skill Modes (Surf/Bhop): This is the standard and necessary setting for hosting community-driven content and custom models.
  • Competitive Leagues: This is generally considered a security risk, as malicious players could use “transparent” textures to gain an unfair tactical advantage through walls and obstacles.
