    Visit your motherboard manufacturer's website and download the latest chipset drivers for your specific model. These are crucial for system stability and communication.

  • Update Monitor Firmware Low impact

    Check your monitor manufacturer's website for any available firmware updates. These can sometimes improve display latency or compatibility.

5.Configure Monitor and Display Settings

Properly set up your display to ensure you're getting the lowest possible latency from your high refresh rate monitor.

  • Set Highest Refresh Rate High impact

    In Windows Display Settings, ensure your monitor is set to its highest available refresh rate (e.g., 144Hz, 240Hz, 360Hz).

  • Disable G-Sync (for competitive play) Medium impact

    While G-Sync prevents screen tearing, it can introduce a slight amount of input lag. For absolute lowest latency, disable it in NVIDIA Control Panel for CS2.

  • Check Monitor Overdrive/Response Time Medium impact

    Access your monitor's OSD (On-Screen Display) menu and set 'Overdrive' or 'Response Time' to its 'Fast' or 'Extreme' setting, but avoid settings that cause inverse ghosting.

6.Advanced BIOS/UEFI Tweaks

For advanced users, specific BIOS settings can further reduce system latency by optimizing CPU and memory interactions.

  • Disable HPET (High Precision Event Timer) Medium impact

    Access your BIOS/UEFI and look for 'HPET' settings. Disabling it (both in BIOS and Windows via `bcdedit /deletevalue useplatformclock`) can sometimes reduce input latency, though results vary.

  • Enable XMP/DOCP for RAM Medium impact

    Ensure your RAM is running at its advertised speeds by enabling the 'XMP' (Intel) or 'DOCP' (AMD) profile in your BIOS. Faster RAM can reduce CPU bottlenecks.

  • Disable C-States Low impact

    In BIOS, disable CPU 'C-States' (CPU Power Management). This prevents the CPU from entering low-power states, ensuring it's always ready for peak performance, albeit with slightly higher power consumption.
