Introduction

Counter-Strike 2 (CS2) is a fast-paced first-person shooter where every millisecond counts. For competitive players, optimizing both latency and performance can provide a significant advantage. This comprehensive guide covers everything from in-game settings to advanced Windows and hardware configurations to help you achieve the lowest latency and best performance possible.

Prerequisites

  • A high-refresh-rate monitor (144Hz or above recommended)
  • Wired internet connection
  • Latest GPU drivers (NVIDIA or AMD)
  • Administrative access to Windows and BIOS

Step 1: In-Game Settings

  1. Resolution: Set to your monitor's native resolution for clarity or lower it to gain higher FPS.
