    Add `-novid -high -threads X +fps_max 0` (replace X with your CPU's physical core count) to your CS2 launch options in Steam.

  • Disable Console Pop-up Low impact

    Add `-console` if you want the console to open automatically, otherwise omit it to prevent potential stuttering on startup.

  • Refresh Rate Command Medium impact

    Add `-freq X` or `-refresh X` (replace X with your monitor's refresh rate, e.g., 144) to ensure the game runs at the correct refresh rate.

6.Maintain System Health

Regular system maintenance ensures your PC runs smoothly and prevents performance degradation over time.

  • Close Background Applications Medium impact

    Before launching CS2, close all unnecessary applications, web browsers, and overlays (Discord, Spotify, etc.) to free up RAM and CPU cycles.

  • Monitor Temperatures Medium impact

    Use software like MSI Afterburner to monitor your CPU and GPU temperatures. Overheating can lead to throttling and performance drops.

  • Disk Cleanup Low impact

    Periodically run Windows Disk Cleanup and consider defragmenting your drive if it's an HDD (SSDs do not need defragmentation).
