Apex Legends Lowest Input Lag Settings: Cut Delay and React Faster
Published
On this page
Apex Legends moves fast, and the player whose shots and movement register first usually wins the third-party fight. Most of the input lag in Apex is controllable through the video menu, a couple of launch options, and your Windows setup. Here is the exact configuration for the lowest input lag in Apex Legends.
Reflex on, V-Sync off, exclusive fullscreen, and an fps_max cap below your refresh — that’s the low-latency core.
Enable NVIDIA Reflex
Apex Legends natively supports NVIDIA Reflex. In Settings → Video, set NVIDIA Reflex to Enabled + Boost. Reflex stops the CPU from running ahead of the GPU and removes render-queue latency, which is most valuable in busy end-game circles where frames drop. On AMD cards, enable Radeon Anti-Lag (or Anti-Lag 2 where supported) in Adrenalin instead.
Use exclusive Fullscreen
Set Display Mode to Full Screen, not Borderless Window. Exclusive fullscreen skips the desktop compositor and removes a frame of presentation delay, and it lets G-Sync/FreeSync operate correctly.
Cap FPS with +fps_max below your refresh
Apex limits to 144 by default, but you should set your own cap. Add it to your launch options in the Origin/Steam game properties, for example +fps_max 138:
| Monitor refresh | Suggested cap |
|---|---|
| 144 Hz | +fps_max 138 |
| 165 Hz | +fps_max 158 |
| 240 Hz | +fps_max 234 |
Capping below your refresh keeps the GPU off 100% so it never builds a queue — the core reason Reflex and a cap work together. More on the method in How to Cap Your FPS Correctly.
Turn off V-Sync and latency-adding settings
- V-Sync: Disabled. Use G-Sync/FreeSync plus your cap for tear-free, low-latency frames.
- Adaptive Resolution FPS Target: 0. Leaving this on lets the game throttle resolution dynamically and can add inconsistency.
- Model/Effects/Texture Detail: lower these to keep the GPU below full load on weaker cards.
Keep the GPU below 99%
If the GPU sits at 99–100%, frames queue up and latency climbs. The combination of Reflex plus an fps_max cap below your refresh keeps usage in the safe range so inputs reach the screen quickly. Check GPU usage with an overlay during a real match, not just the firing range.
Use a high mouse polling rate
A 1000 Hz (or higher) mouse polling rate samples your aim far more often than a 125 Hz mouse, trimming the input stage. Set the highest stable rate in your mouse software.
Fix Windows-level latency
- Set Windows to a high-performance power plan.
- Enable and test Hardware-Accelerated GPU Scheduling (HAGS).
- Turn on Game Mode in Settings → Gaming.
- Raise your Windows timer resolution with Tier1Timer. The default timer ticks slowly; raising the resolution samples input more often and smooths frame pacing, with Auto Mode that applies on launch and reverts on exit.
Optimize the monitor
Your panel is the last stage of the chain. A high-refresh display with low processing delay shows each frame sooner — confirm its own settings aren’t adding lag. See How to Optimize Your Monitor for Gaming.

The lowest input lag in Apex Legends comes from Reflex Enabled + Boost, exclusive Full Screen, V-Sync off with an fps_max cap below your refresh, and a clean Windows setup. Keep the GPU off the ceiling and your fights resolve in your favor.
Frequently asked questions
How do I reduce input lag in Apex Legends?
Enable NVIDIA Reflex in the video settings, run the game in exclusive Fullscreen, turn V-Sync off, and cap your FPS a few frames below your refresh rate so the GPU stays below full load. Adding +fps_max to your launch options gives you reliable control over the cap. Together these remove most of the controllable delay in Apex.
Does NVIDIA Reflex lower input lag in Apex Legends?
Yes. Apex Legends natively supports NVIDIA Reflex, and it is one of the biggest latency wins on an NVIDIA GPU. It keeps the CPU from queuing frames ahead of the GPU and shortens the render pipeline, which matters most in chaotic late-game fights when frames dip.
Should I cap my FPS in Apex Legends?
Yes. Apex caps at 144 by default, but you should set your own cap with +fps_max in launch options, a few frames below your refresh rate. Capping keeps the GPU below 100% so it never builds a render queue, which keeps latency low and frame times consistent during high-action moments.
What causes input delay in Apex Legends?
The usual chain: mouse polling, CPU frame prep, render queue, GPU render time, and your monitor. V-Sync, borderless windowed mode, a GPU pinned at 100%, and heavy settings all add delay. Reflex, exclusive fullscreen, V-Sync off, and a sensible cap trim the controllable stages.
Does timer resolution reduce input lag in Apex Legends?
It can improve input-sampling consistency and frame pacing at the system level. The default Windows timer ticks slowly, and raising the resolution with Tier1Timer samples inputs more often. It is a Windows-wide tweak rather than an Apex setting, so use it to support Reflex and your FPS cap.
