Overwatch Lowest Input Lag Settings (Reflex, Buffering, Cap)
By Tier1Settings Updated Published
On this page
For the lowest input lag in Overwatch, set NVIDIA Reflex to Enabled + Boost, turn Reduce Buffering on, use Fullscreen with V-Sync off, and cap your FPS a few frames below your refresh rate. All five are in Options → Video. Blizzard dropped the “2” from the name on 10 February 2026, and these settings are the same whether your launcher says Overwatch or Overwatch 2. The rest of the delay comes from your mouse and Windows setup, covered below.
Reflex on, Reduce Buffering on, Fullscreen, V-Sync off, and a frame cap below your refresh — that’s the low-latency core.
Enable NVIDIA Reflex
Overwatch natively supports NVIDIA Reflex. In Options → Video, set NVIDIA Reflex to Enabled + Boost (the choices are Disabled, Enabled and Enabled + Boost). Reflex stops the CPU from running ahead of the GPU and removes render-queue latency, which is most valuable in chaotic teamfights where frames drop. Boost also raises GPU clocks when the game is CPU-limited; if your FPS drops noticeably with it, use plain Enabled. On AMD cards, enable Radeon Anti-Lag in Adrenalin instead.
Turn on Reduce Buffering
In the same Video menu, set Reduce Buffering to On. This shrinks the render-ahead queue so the game holds fewer frames before presenting them. With Reflex on there is little queue left to trim, but Reduce Buffering costs nothing on a capped frame rate, so leave it on. It matters most on AMD and older GPUs without Reflex.
Use Fullscreen
Set Display Mode to Fullscreen, not Borderless. Fullscreen gives the game direct control of presentation, so the desktop compositor can’t add a frame of delay, and G-Sync/FreeSync behave predictably.
Cap FPS below your refresh
Use the in-game Frame Rate limiter (set Limit FPS to Custom) and cap a few frames below your refresh rate:
| Monitor refresh | Suggested cap |
|---|---|
| 144 Hz | 138 |
| 165 Hz | 158 |
| 240 Hz | 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.
Turn off V-Sync and latency-adding settings
- V-Sync: Off. Use G-Sync/FreeSync plus your cap for tear-free, low-latency frames.
- Triple Buffering: Off. It adds buffered frames and delay.
- Dynamic Render Scale: Off. Set Render Scale to a fixed value so resolution doesn’t fluctuate mid-fight.
- Lower Texture Quality and Effects Detail on weaker GPUs to keep usage below full load.
Keep the GPU below 99%
If the GPU sits at 99–100%, frames queue up and latency climbs. The combination of Reflex plus a frame 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 practice 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.
- Optionally raise your Windows timer resolution with Tier1Suite for steadier frame pacing under a cap. It doesn’t change how often your mouse is read (that’s the polling rate), and Auto Mode applies it on launch and reverts on exit. See the ultimate guide to timer resolution.

The lowest input lag in Overwatch comes from Reflex Enabled + Boost, Reduce Buffering on, Fullscreen, V-Sync off with a frame cap below your refresh, and a clean Windows setup.

Frequently asked questions
How do I reduce input lag in Overwatch?
Enable NVIDIA Reflex, turn Reduce Buffering on, run the game in Fullscreen, disable V-Sync, and cap your frame rate a few frames below your refresh rate. These keep the GPU off 100% and shorten the render pipeline. Together they remove most of the controllable delay in Overwatch.
Does NVIDIA Reflex lower input lag in Overwatch 2?
Yes. Overwatch 2 natively supports NVIDIA Reflex on supported GPUs, and it is one of the biggest latency wins. It stops the CPU from queuing frames ahead of the GPU and trims render-queue delay, which matters most in busy teamfights when frames dip.
What does Reduce Buffering do in Overwatch 2?
Reduce Buffering shrinks the render-ahead queue so the game holds fewer frames before displaying them. With it on, your inputs reach the screen sooner at the cost of a slightly less smooth frame delivery. For competitive play the lower latency is almost always worth it.
Should I cap my FPS in Overwatch 2?
Yes. Use the in-game Frame Rate limiter and set a cap a few frames below your monitor's refresh rate. Capping keeps the GPU below 100% so it never builds a render queue, which keeps latency low and frame times consistent during chaotic fights.
Should I use Enabled or Enabled + Boost for Reflex in Overwatch?
Start with Enabled + Boost. Boost raises GPU clocks when the game is CPU-limited so frames are submitted sooner. Some players see lower FPS with Boost on, so if your frame rate drops noticeably, switch to plain Enabled, which keeps most of the latency reduction.
Does timer resolution reduce input lag in Overwatch?
Not directly. Timer resolution changes how precisely Windows wakes threads and paces frames, which can make frame-rate caps and frame times more consistent. It does not change how often your mouse is read, which is set by its polling rate. Treat it as a frame-pacing tweak that supports Reflex and your FPS cap, not a latency setting.
