Marvel Rivals Lowest Input Lag Settings: Cut Delay and React Faster
Published
On this page
Marvel Rivals is a fast, ability-heavy hero shooter where reacting first decides duels — and as a demanding Unreal Engine 5 game it gives input lag plenty of places to creep in. The fix is the same competitive recipe, applied to a GPU-heavy title. Here is the exact setup for the lowest input lag in Marvel Rivals.
Reflex on, V-Sync off, exclusive fullscreen, frame gen off, and an FPS cap that keeps this UE5 game’s GPU off the ceiling.
Enable NVIDIA Reflex
Marvel Rivals natively supports NVIDIA Reflex. In Settings → Graphics, set NVIDIA Reflex Low Latency to On + Boost. Reflex stops the CPU from running ahead of the GPU and removes render-queue delay — especially valuable here because the engine is heavy and frames dip during ultimate-heavy team fights. On AMD cards, enable Radeon Anti-Lag (or Anti-Lag 2 where supported) in Adrenalin instead.
Use exclusive Fullscreen
Set Display Mode to Fullscreen, not Borderless Windowed. Exclusive fullscreen skips the desktop compositor and removes a frame of presentation delay, and it lets G-Sync/FreeSync operate correctly.
Cap FPS below your refresh rate
Because Marvel Rivals is demanding, the GPU pins at 100% easily and builds a render queue, raising latency. Cap a few frames below your refresh so the GPU keeps headroom:
| Monitor refresh | Suggested cap |
|---|---|
| 144 Hz | 138 |
| 165 Hz | 158 |
| 240 Hz | 234 |
If your hardware can’t sustain that, lower graphics settings rather than chasing an impossible cap. Capping method: How to Cap Your FPS Correctly.
Turn off V-Sync and frame generation for competitive play
- V-Sync: Off. Use G-Sync/FreeSync plus your cap for tear-free, low-latency frames.
- Frame Generation (DLSS/FSR FG): Off for competitive play — it raises the displayed frame number but adds latency rather than removing it. See Frame Generation Input Lag Explained for the why.
- Upscaling (DLSS/FSR): use Quality or Balanced to ease GPU load and keep frames high — that helps latency, unlike frame gen.
Keep the GPU below 99%
A GPU at 99–100% queues frames and adds delay — the core reason Reflex plus a cap matter on a heavy game like this. Lower post-processing, shadows, and effects as needed to keep usage in the safe range, and verify with an in-game or overlay GPU meter during a real match.
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
The panel is the final 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 Marvel Rivals comes from Reflex On + Boost, exclusive Fullscreen, V-Sync and frame gen off, and an FPS cap that keeps this UE5 game’s GPU off the ceiling. Keep the pipeline short and your shots land before the enemy’s.
Frequently asked questions
How do I reduce input lag in Marvel Rivals?
Enable NVIDIA Reflex in the graphics 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. Because Marvel Rivals is a demanding Unreal Engine 5 game, also turn frame generation off for competitive play, since it raises the frame counter but adds latency.
Does NVIDIA Reflex lower input lag in Marvel Rivals?
Yes. Marvel Rivals 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, shortening the render pipeline. Enable it with the Boost option when available, especially since the game is GPU-heavy and frames can dip in busy team fights.
Should I cap my FPS in Marvel Rivals?
Yes. Marvel Rivals is demanding, so the GPU can easily hit 100% and build a render queue. Cap a few frames below your refresh rate to keep the GPU below full load, which keeps Reflex effective and frame times steady. If your hardware can't reach your refresh, lower graphics settings rather than chasing an impossible cap.
What causes input delay in Marvel Rivals?
The usual chain plus engine load: mouse polling, CPU frame prep, render queue, GPU render time, and the monitor. As a GPU-heavy Unreal Engine 5 title, a pinned GPU, V-Sync, borderless mode, and frame generation all add delay. Reflex, exclusive fullscreen, V-Sync off, and an FPS cap trim the controllable stages.
Does timer resolution reduce input lag in Marvel Rivals?
It can improve input-sampling consistency and frame pacing system-wide. The default Windows timer ticks slowly, and raising the resolution with Tier1Timer samples inputs more often. It is a Windows-level tweak rather than a Marvel Rivals setting, so use it to support Reflex and your FPS cap.
