Halo Infinite Lowest Input Lag Settings for Snappy Aim
Published
On this page
Halo Infinite’s aim rewards a fast, consistent connection between your input and the screen — and unlike many competitive shooters, it supports NVIDIA Reflex, which is the single biggest latency lever you have. This guide covers Reflex plus every other setting that meaningfully reduces input lag in Halo Infinite.
Reflex does the heavy lifting on NVIDIA hardware, but a tight FPS cap, Fullscreen, and timer resolution all stack on top to remove the rest of the controllable delay.
The short version
- NVIDIA Reflex → On + Boost (NVIDIA GPUs) — the biggest single win.
- Exclusive Fullscreen — not Borderless.
- Max Frame Rate cap at refresh minus 3, V-Sync Off.
- Lower GPU-heavy settings to keep frame times low.
- Timer resolution applied via Tier1Timer.
Everything below is the detail.
In-game latency settings
Halo Infinite exposes its latency options directly in Settings → Video.
NVIDIA Reflex Low Latency
Set Minimum Frame Rate off and NVIDIA Reflex Low Latency → Ultra (also shown as On + Boost) if you have an NVIDIA GTX 900-series or newer GPU.
Reflex works inside the game and the driver together to keep the render queue empty, so frames are rendered just in time for display. It typically beats driver-only Ultra-Low Latency Mode because the game feeds the GPU precise pacing information. This is the most important setting on this page.
On AMD, Reflex isn’t available — use Anti-Lag in Adrenalin instead (see driver section).
Frame rate cap
Set Max Frame Rate to your refresh minus 3 — 141 on 144Hz, 237 on 240Hz.
- Uncapped lets the GPU render ahead and queue frames, adding latency spikes.
- V-Sync On buffers a full frame — never use it competitively.
- A tight cap plus Reflex is the lowest-latency combination available in Halo.
Window mode
Set Window Mode → Fullscreen (exclusive). Borderless routes through the Windows compositor and adds ~a frame of latency.
In-game graphics settings for latency
Lower GPU load means lower frame times and a shorter render queue. Reflex helps most when the GPU isn’t pinned at 100%, so keep these modest:
| Setting | Value |
|---|---|
| Quality Preset | Low / Medium |
| Texture Quality | High (cheap on VRAM, not frame time) |
| Shadow Quality | Low |
| Ambient Occlusion | Off / Low |
| Effects Quality | Low |
| Volumetric Fog | Low |
| Anti-Aliasing | Low or TAA |
| Motion Blur | Off |
| Sharpening | To taste |
Shadow Quality and Volumetric Fog are the heaviest GPU consumers here. Lowering them keeps GPU usage below 100%, which is the condition where Reflex delivers its full latency reduction.
GPU driver settings
NVIDIA — NVIDIA Control Panel
- Manage 3D settings → Program Settings → Add Halo Infinite.
- Low Latency Mode → On (Reflex overrides this in-game, but On is a safe default for menus).
- Power Management Mode → Prefer Maximum Performance.
- Vertical sync → Off.
AMD — AMD Software: Adrenalin
- Open Gaming → Halo Infinite.
- Anti-Lag → Enabled — AMD’s answer to Reflex/Ultra-Low Latency.
- Wait for Vertical Refresh → Off.
System settings
Windows power plan
Control Panel → Power Options → High Performance (or Ultimate Performance). Balanced lets the CPU downclock between operations, adding scheduler jitter. High Performance keeps input handling and frame scheduling snappy. See Best Windows Power Plan for Gaming.
Timer resolution
The Windows default system timer fires every 15.6ms. Lowering it to 0.5ms gives the scheduler 31× more precision, so input events are handled in the next tick instead of waiting for the next 15.6ms window. It stacks with Reflex — Reflex trims the render queue, timer resolution tightens the scheduler that delivers those frames.

Game Mode and overlays
- Enable Windows Game Mode (Settings → Gaming → Game Mode → On).
- Disable overlays you don’t need — Discord, Steam, Xbox Game Bar. Each adds a rendering layer that can interfere with frame delivery. See Disable Xbox Game Bar and Game DVR.
Peripherals
- Wired mouse at 1000Hz polling (or higher on supported mice) removes any radio latency.
- Controller players: a wired controller and a lower-latency wireless dongle both help; Bluetooth is the worst option for input lag.
- Monitor in Game / FPS mode, not Cinema.
- DisplayPort over HDMI for lower overhead at high refresh.

Network vs input lag
Input lag and network lag are separate problems. If aim feels off only on certain servers, it’s the network:
Quick-reference checklist

NVIDIA Reflex, a tight FPS cap, exclusive Fullscreen, and timer resolution cover the vast majority of controllable input lag in Halo Infinite. Reflex is the biggest single lever on NVIDIA hardware — stack the rest on top and your aim will feel as sharp as your monitor allows.
Frequently asked questions
How do I reduce input lag in Halo Infinite?
Enable Minimum Frame Rate / low-latency settings in-game, run exclusive Fullscreen, cap your FPS a few frames below your refresh rate with V-Sync off, and turn on NVIDIA Reflex if you have an NVIDIA GPU. Halo Infinite supports Reflex, which is the single biggest latency win. Add the High Performance power plan and timer resolution via Tier1Timer to tighten frame pacing further.
Does Halo Infinite support NVIDIA Reflex?
Yes. Halo Infinite has NVIDIA Reflex Low Latency support. Set it to On or On + Boost in the video settings if you have an NVIDIA GTX 900-series or newer GPU. Reflex reduces the render queue at the driver and game level together, which typically cuts system latency by a larger margin than driver-only Ultra-Low Latency Mode.
What FPS cap should I use in Halo Infinite for the lowest input lag?
Cap at your refresh rate minus about 3 (for example 141 on 144Hz, 237 on 240Hz) using the in-game Max Frame Rate setting. A tight cap keeps the GPU from queuing frames and pairs well with Reflex. Uncapped lets frames queue and adds latency; V-Sync adds a full frame of delay and should stay off for competitive play.
Should I use Fullscreen or Borderless in Halo Infinite for input lag?
Use exclusive Fullscreen. It gives the game direct access to the display and bypasses the Windows desktop compositor that Borderless routes through, which adds roughly a frame of latency. In ranked Arena where the first shot in a duel matters, that frame counts.
Does timer resolution help input lag in Halo Infinite?
Yes. Windows schedules frame delivery and input on a system timer that defaults to 15.6ms. Lowering it to 0.5ms gives the scheduler much finer precision, reducing the latency jitter between your input and the next rendered frame. It stacks with NVIDIA Reflex rather than replacing it — Reflex trims the render queue, timer resolution tightens the scheduler.
