For faster close-range fights, reduce the time between your click and the first visible frame: select the monitor’s highest refresh rate, keep FPS high and stable during combat, enable NVIDIA Reflex when the game supports it, and use moderate monitor overdrive without inverse ghosting. Lower graphics quality only as far as needed to prevent GPU-bound frame-time spikes. These changes improve the complete input-to-display path; a high average FPS number by itself does not prove low latency.
What reaction time means in an FPS
Your physical reaction is only one part of a gunfight. After you move the mouse or press a button, the input must be sampled, processed by the game and CPU, rendered by the GPU, scanned to the display, and shown by pixels that are still transitioning. The total is end-to-end, or click-to-photon, latency.
Longer latency delays every correction. NVIDIA explains that the feedback loop becomes longer at higher latency, reducing precision; it also warns that an additional 30–40 milliseconds can be enough to miss a game-winning frag. In a close fight, that delay can appear as an opponent seeing your shot, your crosshair arriving late, or a quick counter-strafe feeling unresponsive.

Recommended baseline settings
| Control | Starting point | Why it matters |
|---|---|---|
| Display refresh rate | Highest supported Hz, selected in both the operating system and the game | Higher refresh gives the display more opportunities to show a newly rendered frame and lowers display latency. |
| Frame rate | High, stable FPS that the system can sustain in fights | More rendered frames create more chances for an input to appear; consistency prevents uneven aim feedback. |
| NVIDIA Reflex | Low-Latency mode enabled in supported games | Coordinates CPU and GPU work for just-in-time rendering. |
| Graphics quality | Reduce GPU-heavy options when they cause GPU saturation or spikes | Raw render time still contributes to click-to-photon latency, even with Reflex. |
| Motion blur | Off, if the game exposes the setting | Removes a visibility obstruction; this is a clarity preference, not a universal measured reaction-time guarantee. |
| Monitor overdrive | Normal or first overdrive level | Improves pixel transitions without immediately introducing inverse ghosting. |
| Synchronization | Use variable-refresh or other tearing control only when its latency is acceptable | Tearing-free output can be worthwhile, but synchronization behavior differs by frame rate and display. |
Set the highest refresh rate correctly
Choose the rate in the operating system
- Open Settings > System > Display.
- Select Advanced display.
- Choose the gaming monitor and set Choose a refresh rate to its highest supported value.
- Confirm the selected value after applying it; reconnecting a display, changing cables, or installing a driver can return it to a lower default.
Match the game to the display
In the game’s video or display menu, select the same refresh rate. Exclusive fullscreen, borderless fullscreen, and windowed modes can expose different refresh-rate behavior, so verify the actual mode the game is using. If the game shows an in-game Hz readout, check it while running; do not assume that buying a 240Hz panel means the game is outputting 240Hz.
Refresh rate and latency are related but not identical. A 60Hz panel refreshes every 16.7 milliseconds, 144Hz about every 6.9 milliseconds, and 240Hz about every 4.2 milliseconds. Those intervals describe display opportunities, not the entire system delay. A slow render queue, a saturated GPU, or excessive synchronization can still dominate the result.
Keep FPS high and frame times stable
Higher FPS reduces the time between rendered frames. It also gives a new mouse input more chances to be included in an upcoming frame. The useful target is the rate your PC can hold during the busiest close-range moments, not the number shown while looking at an empty wall.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsPrioritize sustained performance
- Watch FPS and frame-time data while fighting, throwing effects, or entering a crowded area.
- Use a cap only when it makes frame times more consistent or prevents the GPU from remaining fully saturated. A stable cap is preferable to an uncapped rate that oscillates sharply.
- Lower the settings that materially increase GPU render time first, such as resolution scale, shadows, volumetric effects, reflections, and high-cost post-processing when those controls exist.
- Retest after each major change. A setting that raises the practice-range average may still hurt real matches if it creates spikes.
NVIDIA Research reported perception benefits across its tested range up to 500 frames per second in a 2026 frame-rate study, with the largest improvement occurring from very low rates and continued gains through the tested range. That result does not promise a specific advantage at every FPS or game, but it supports avoiding unnecessarily low frame rates when your hardware can sustain more.

Enable NVIDIA Reflex when available
NVIDIA Reflex Low-Latency mode is implemented by the game. It synchronizes CPU and GPU work so frames are rendered closer to the moment they are needed instead of building a long queue. This is designed to reduce click-to-photon latency and keep the input-to-frame relationship more predictable.
- Open the game’s graphics, video, or latency settings.
- Find the NVIDIA Reflex or Low-Latency option and enable it.
- If the game offers more than one Reflex mode, start with the standard enabled mode and use the game’s own description for any additional option.
- Play a repeatable close-range scenario and watch frame-time or latency telemetry if the game provides it.
Reflex cannot remove the time required to render a complex frame. If the GPU is overloaded, reduce GPU-heavy settings as well. Reflex is a scheduling aid, not a substitute for sufficient GPU headroom.
Adjust graphics for latency, not just image quality
Find out whether the GPU or CPU is limiting you
A GPU-bound system spends most of each frame waiting for rendering to finish. Lowering resolution or shader-heavy effects should then reduce frame time. A CPU-bound system may show little improvement from lower resolution; reducing crowd, simulation, or view-distance settings may help instead, if the game exposes them.
Use the game’s performance overlay, a driver overlay, or a frame-time graph to identify the limit. Average FPS can hide the short spikes that make a weapon swap or flick feel late. Compare the worst moments of a match rather than selecting settings from a quiet benchmark scene.

Keep visibility settings separate from latency settings
Disable motion blur when possible if it smears targets during a fast turn. Treat this as a visual-clarity choice: the cited NVIDIA latency studies do not establish one universal reaction-time improvement from disabling blur. Other effects, such as film grain, chromatic aberration, and heavy depth of field, can also obscure edges; remove them when the game allows and when you can do so without losing useful visual information.
Use monitor overdrive without creating inverse ghosting
Overdrive increases the voltage used to move pixels between shades. The goal is to reduce ordinary ghosting behind a moving target. Too much overdrive can overshoot the target color, producing bright or dark trails commonly called inverse ghosting or coronas. Those artifacts can make a strafing opponent harder to read than ordinary blur.
- Open the monitor’s on-screen display and find Response Time, Overdrive, or a similar control.
- Choose Normal, Standard, or the first level above disabled.
- Test a moving-target scene at the refresh rate you actually use.
- Increase one step only if normal ghosting remains distracting and bright or dark overshoot is absent.
- Return to the lower setting if you see inverse-ghosting trails, especially in dark-to-bright transitions.
Overdrive is panel-specific. The fastest label is not automatically the clearest setting, and a mode that looks acceptable at one refresh rate can overshoot at another.
Choose synchronization with latency in mind
Variable-refresh displays can remove tearing by matching scanout to the frame rate. Synchronization can also add queuing or waiting when the frame rate reaches a display limit, so evaluate the result with a latency overlay or a consistent in-game test rather than assuming every tear-free mode feels identical.

NVIDIA notes that variable refresh can be combined with V-SYNC and Reflex to avoid tearing while keeping latency low when the frame rate is below the display’s maximum. If your frame rate regularly exceeds the panel limit, test the game’s available cap and synchronization combinations. Keep the option that gives you acceptable clarity without making aim feel delayed; competitive players who prefer the absolute lowest latency may accept some tearing.
What the evidence says about 240Hz and latency
NVIDIA Research’s 2019 esports study describes optimized competitive configurations reaching approximately 15 milliseconds of latency with a 240Hz display. That figure is an example of a complete configuration, not a guarantee for every PC, game, monitor, or peripheral.
The same research found a clear benefit from reduced latency in targeting-task completion. Once the inherent latency advantage of a high-refresh display was removed, the independent effect of refresh rate was relatively small. In practical terms, moving from an unstable 120 FPS setup to a well-tuned 240Hz system can help because both the frame cadence and display interval improve; simply changing the monitor while leaving a slow render pipeline intact will not deliver the full benefit.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A 240Hz monitor is therefore a direct hardware fit for players who can sustain high FPS and care about close-range tracking. It is less compelling if your system spends fights below the panel’s refresh range or if the monitor’s pixel response produces visible ghosting.

A practical setup sequence
- Set the operating system and game to the monitor’s maximum refresh rate.
- Start with a competitive graphics preset, then lower GPU-heavy settings until fight-time frame times are stable.
- Enable NVIDIA Reflex Low-Latency mode if the title supports it.
- Disable motion blur and distracting post-processing for a clearer view.
- Set monitor overdrive to Normal or the first level, then inspect moving targets for ordinary and inverse ghosting.
- Test synchronization with your variable-refresh display. Keep it only if the resulting latency is acceptable.
- Record the frame rate, frame-time behavior, and subjective responsiveness in the same close-range scenario before and after changes.
Troubleshooting common problems
The game still feels delayed at high FPS
- Confirm the monitor is actually running at the selected Hz rather than its factory default.
- Check for GPU saturation and frame-time spikes during fights; lower GPU-heavy options if necessary.
- Verify that Reflex is enabled in the game, not only a similarly named driver setting.
- Test synchronization modes, since a tear-free setting can feel slower on some frame-rate patterns.
Moving targets have bright or dark trails
- Reduce monitor overdrive by one level.
- Retest at the exact refresh rate used in the match.
- Check whether variable refresh changes the panel’s overdrive behavior; some displays use different response tuning at different rates.
FPS is high but aim feels uneven
- Inspect frame time rather than the average FPS counter.
- Look for spikes when effects, players, or new areas appear.
- Use a modest cap if it removes oscillation and leaves rendering headroom.
- Recheck background capture, overlays, and synchronization after every graphics-driver or game update.
Tearing appears after lowering latency
Test variable-refresh synchronization with Reflex while your frame rate is below the monitor limit, as NVIDIA describes this combination as a way to reduce tearing without giving up as much latency. If the result still feels delayed, compare it with synchronization disabled and decide whether the visual cost of tearing is acceptable for your play style.
How to judge a monitor or settings change
Compare options on six separate axes: end-to-end latency, sustained FPS during close fights, refresh rate, pixel response and ghosting, image clarity, and support for Reflex or another in-game low-latency mode. Do not use average FPS as a proxy for click-to-photon latency. A useful comparison repeats the same scenario, records frame-time behavior, confirms the actual refresh rate, and checks the screen for ghosting artifacts.
For competitive play, prioritize a stable render pipeline and timely display updates before increasing visual quality. Once those are controlled, tune clarity settings and overdrive to make targets easier to read without introducing artifacts. This order prevents a sharper-looking but slower configuration from undermining the reaction-time advantage you were trying to gain.
