Counter Strike 2 Keyboard and Mouse Not Working Issue: Counter-Strike 2 (CS2) is a precision-based competitive shooter where keyboard and mouse responsiveness is essential. Every movement, weapon switch, recoil adjustment, and headshot depends on accurate input. When the keyboard or mouse suddenly stops working, becomes unresponsive, experiences input lag, or fails to register actions correctly, the game becomes virtually unplayable.

Many players have reported issues such as the keyboard not responding after launching the game, the mouse cursor being stuck, movement keys not working, random input delays, inability to look around, or controls freezing during matches. Sometimes the problem appears after a game update, a Windows update, a graphics driver installation, or a change in game settings.

Fortunately, most keyboard and mouse issues in Counter-Strike 2 are caused by software conflicts, corrupted game files, incorrect settings, USB problems, outdated drivers, or overlay applications. In this comprehensive guide, we’ll cover every proven solution to restore proper keyboard and mouse functionality in CS2.
