: Ensure you have an NVIDIA GeForce GTX 900 series or newer GPU.

: Look for the "NVIDIA Reflex Low Latency" setting in the video options of games like Fortnite , Valorant , or Call of Duty .

If you aren't using an NVIDIA card, you might be looking for the built into G-SYNC monitors, or software like ISLC (Intelligent Standby List Cleaner) , which clears background memory to prevent micro-stutters.

: This mode keeps the GPU clock speeds high to further minimize latency, especially in CPU-bound scenarios. Alternative: Monitor-Specific Tools

In fast-paced games, input lag—the delay between clicking your mouse and seeing the action on screen—can be the difference between winning and losing. These tools work by optimizing the communication between your CPU and GPU to keep them in sync, effectively "cutting out the middleman" of the render queue. How to Use NVIDIA Reflex

The tool often cited in this specific context is (or its open-source alternative, AMD Anti-Lag+ ), which is designed to reduce system latency in competitive gaming. Why You "Need" This Tool
