Low latency for gaming—the delay between pressing a button and seeing the result—can be reduced by updating the right settings, using a wired connection, and picking the correct game mode.
Every millisecond counts when you’re in a split-second firefight. The delay between your input, the game server, and your screen reacting is the difference between a clutch win and a respawn screen. You don’t need a new PC or a magic registry hack to make it better. The real fixes are already built into your hardware and software—most players just have them turned off.
The biggest levers are in your graphics driver, display settings, and how your PC connects to the internet. Here’s exactly what to change, starting with the tools that reduce the most lag.
Turn On NVIDIA Reflex or Ultra Low Latency Mode
The single most impactful setting for latency reduction is NVIDIA Reflex, when your game supports it. Reflex syncs the CPU and GPU work queue to just-in-time delivery, trimming the delay between click and screen update.
In a game that supports Reflex—titles like Valorant, Fortnite, and Apex Legends—open the video or graphics settings menu and enable NVIDIA Reflex Low Latency. If your game doesn’t list Reflex, open the NVIDIA Control Panel, go to Manage 3D Settings, and set Low Latency Mode to Ultra. This driver-level option reduces queuing but only kicks in when Reflex itself isn’t available.
For Intel GPU users, the best first step is to disable V-Sync in the game’s settings and, when possible, turn on Adaptive Sync if your monitor supports it. Intel’s official guidance recommends capping frame rate just under the display’s refresh rate, though it also notes that a much higher frame rate can help in some cases.
Set the Display to Its Highest Refresh Rate and Use Exclusive Fullscreen
A higher refresh rate display updates the image more often per second, which directly reduces the time between a frame being ready and you seeing it.
In the NVIDIA Control Panel, navigate to Change resolution and select the highest refresh rate your monitor supports (for example, 144Hz or 240Hz). Then, in any game’s video settings, switch the display mode to Exclusive Fullscreen rather than borderless windowed or windowed. Exclusive Fullscreen bypasses the Windows compositor, cutting a measurable slice of input lag. This applies only when the game offers the option—some modern titles use borderless fullscreen exclusively.
If you own a G-SYNC monitor, enable G-SYNC Esports mode in the monitor’s on-screen display or NVIDIA Control Panel. This mode disables variable backlight processing, further trimming display-side latency.
Turn Off V-SYNC and Enable Windows Game Mode
V-SYNC is a latency killer. It forces the GPU to wait for the monitor’s refresh cycle, effectively adding one frame of delay at minimum—often more under load. To eliminate this, open your game’s video settings and disable V-SYNC.
On the Windows side, enable Game Mode by going to Settings > Gaming > Game Mode and toggling it on. This gives game processes higher CPU and GPU priority, which can reduce latency. NVIDIA specifically references Game Mode in its optimization guide as a setting that helps when active.
If you find the image tearing bothersome (the cost of turning off V-SYNC), try capping your frame rate to just under your monitor’s refresh rate in the game’s settings or in the NVIDIA Control Panel—this reduces tearing while keeping latency lower than V-SYNC would.
Fix the Connection: Wired Over Wireless, and the Right Server
Input latency isn’t just about your PC—network quality matters just as much. The single most reliable improvement is switching from Wi‑Fi to a wired Ethernet connection. Intel’s guidance explicitly recommends wired connections over wireless ones when possible, and that advice holds across any competitive title.
If your gaming PC can’t reach the router directly, consider a dedicated gaming access point that creates a stable wired path.
Beyond the hardware, always pick the closest game server or region in your game’s settings. Close background apps that stream or download, and pause any ongoing updates—bandwidth contention adds jitter and average ping. Changing your DNS to a faster resolver like Cloudflare or Google may improve initial connection speed, but it does not directly reduce in-game ping during play.
FAQs
Does a better graphics card reduce gaming latency?
Yes—a faster GPU reduces render latency, which is the time it takes to generate a frame. However, driver and software settings like NVIDIA Reflex can have a bigger impact per dollar than upgrading hardware alone.
Is it better to cap or uncap frame rate for low latency?
Intel recommends capping frame rate just under the display’s refresh rate as a starting point, but notes that running uncapped can sometimes lower latency further. The best approach depends on your specific GPU and game; test both ways.
Can a high refresh rate monitor reduce input lag?
It reduces display latency, not network or input lag. A 240Hz monitor shows each frame sooner than a 60Hz one, which makes your clicks and screen updates feel more immediate. Set it to its highest refresh rate in the driver panel.
