CS2 update, September 28, 2026: Rush and Castle fixes

• Fixed pixel-gaps in various Rush rooms.
• Clipping adjustments in T/CT Castle rooms.

Valve released a technical patch addressing geometric issues on Rush mode maps. Pixel-gaps are microscopic texture and model cracks that can cause visual artifacts and potential physics errors. Clipping adjustments in the castle affect invisible barriers that define where players can or cannot be. For regular players, this means cleaner visuals and more predictable environmental interactions.

Community server administrators running Rush mode or maps with castle locations should ensure their servers are updated. If servers run custom configs or plugins tied to these areas' geometry, verification and adjustment may be needed. The update requires no map reinstallation or core server configuration changes.

The changes target specific geometric elements in Rush and castle zones, so testing these map sections and checking for unexpected movement or obstacle interaction changes is recommended.
