CS2 Interp Settings Guide: Optimize Your Hit Registration and Reduce Lag
Interpolation in CS2 helps smooth out player movements by filling gaps between server updates. However, default settings can cause delays and affect gameplay. Here's how to optimize your settings for better performance.
Key Interp Commands:
cl_updaterate 128
- Sets how often your client receives server updates
- Higher values reduce teleporting effects
- Optimal for 128-tick servers
cl_interp_ratio 1
- Controls interpolation delay multiplier
- Keep at 1 for minimal lag
- Works with cl_interp for optimal performance
cl_interp 0.015625 or 0.03125
- Controls server-client delay
- Use 0.015625 (15ms) for stable connections
- Use 0.03125 (31ms) for less stable connections
Setting Up Autoexec:
- Navigate to: C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\game\csgo\cfg
- Create/edit autoexec.cfg
- Add these lines:
cl_updaterate 128 cl_interp_ratio 1 cl_interp 0.015625
- Add "+exec autoexec.cfg" to Steam launch options
Important Considerations:
- These settings won't fix poor internet connections
- Experiment with cl_interp values for optimal performance
- Default cl_interp is 0.1 (100ms)
- Consider adjusting only if experiencing delays or poor hit registration
Optimal Usage:
- Stable internet: Use lower interpolation values
- Unstable connection: Use higher values
- Monitor performance and adjust as needed
- Keep settings consistent for muscle memory
