FragPunk Lowest Input Lag Settings for Competitive Play
Published
On this page
FragPunk is a fast 5v5 hero shooter where the first accurate shot usually wins the duel, so every millisecond between your input and the game reacting matters. Because FragPunk runs on the heavier Unreal Engine 5, the biggest latency wins come from keeping the GPU off its ceiling and enabling the engine’s low-latency features — not just tweaking a couple of sliders. Here is the exact configuration for the lowest input lag in FragPunk.
Reflex on, Fullscreen, V-Sync off, and a frame cap below your refresh — that’s the low-latency core on Unreal Engine 5.
Enable NVIDIA Reflex
If your FragPunk video settings expose an NVIDIA Reflex Low Latency option, turn it On (or On + Boost). Reflex keeps the CPU and GPU in sync so frames don’t pile up in the render queue, and it is the single most effective latency setting in any game that supports it. UE5 competitive shooters commonly include it; if yours doesn’t show the toggle, the frame cap below does much of the same work.
Use Fullscreen
Set Display Mode to Fullscreen (exclusive), 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 below your refresh
FragPunk is demanding, so cap at a rate you can actually hold in a team fight, not your best-case menu number. Set the frame limit a few frames below your refresh:
| Monitor refresh | Suggested cap |
|---|---|
| 144 Hz | 141 |
| 165 Hz | 162 |
| 240 Hz | 237 |
Capping below your refresh keeps the GPU off 100% so it never builds a render queue. If you can’t hold a cap near your refresh, lower graphics settings until you can — a stable, held cap beats a higher number that dips mid-fight.
Turn off V-Sync and latency-adding settings
- V-Sync: Off. Use G-Sync/FreeSync plus your frame cap for tear-free, low-latency frames.
- Frame Generation: Off. Frame gen adds latency because it inserts interpolated frames — bad for a competitive shooter. See frame generation input lag explained.
- Anti-aliasing / post-processing: lower these first to bring the GPU under 100%; TSR/TAA at lower quality frees headroom.
- Shadows, effects, and ambient occlusion: low. They scale hard with UE5 scenes and cost frame-time stability.
Keep the GPU below 99%
If the GPU sits at 99–100%, frames queue up and latency climbs. Reflex helps, but a frame cap below your refresh is what reliably keeps usage in the safe range so inputs reach the screen quickly. Check GPU usage with an FPS overlay during a real match, not 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.
- 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. See the ultimate guide to timer resolution.

The lowest input lag in FragPunk comes from NVIDIA Reflex where available, exclusive Fullscreen, V-Sync off with a frame cap you can actually hold, and a clean Windows setup. Because UE5 pushes the GPU hard, keeping usage off the ceiling and your timer resolution raised carries the most weight for consistent, low-latency aim.
Frequently asked questions
How do I reduce input lag in FragPunk?
Enable NVIDIA Reflex if your build exposes it, run the game in exclusive Fullscreen, turn V-Sync off, cap your frame rate a few frames below your refresh rate, and keep the GPU off 100%. FragPunk runs on Unreal Engine 5, which is heavier than most competitive shooters, so keeping the GPU below full load is the single most important step. A high mouse polling rate and a clean Windows setup finish it off.
Does FragPunk support NVIDIA Reflex?
FragPunk is built on Unreal Engine 5, and UE5 competitive shooters commonly expose an NVIDIA Reflex Low Latency option. If the toggle is present in your video settings, turn it on — Reflex drains the GPU render queue and is the most effective single latency setting. If your build doesn't show it, an explicit frame cap below your refresh does much of the same job.
What FPS should I cap FragPunk at?
Cap a few frames below your monitor's refresh — for example 141 on a 144 Hz panel or 237 on a 240 Hz panel. FragPunk is UE5 and demanding, so cap at a rate you can actually hold during a chaotic team fight, not your best-case menu FPS. A stable cap below refresh keeps the GPU off 100% and prevents the render queue that adds latency.
Should I use V-Sync in FragPunk?
No. V-Sync adds a frame or more of delay. Turn it off in the video settings and use G-Sync or FreeSync paired with a frame cap below your refresh rate for tear-free frames without the input penalty.
Does timer resolution reduce input lag in FragPunk?
It can improve input-sampling consistency and frame pacing at the system level. The default Windows timer ticks slowly; raising the resolution with Tier1Timer samples input more often and steadies frame delivery. On a demanding UE5 game like FragPunk, consistent pacing helps keep aim predictable when the GPU is under load.
