Calculate total input-to-display latency in games by adding network ping, frame time, input lag, and display response. See where delay comes from and how to reduce it.
The total delay from pressing a button to seeing the result on screen combines multiple latency sources: network ping, CPU/GPU frame time, input device lag, and display response time. In competitive gaming, every millisecond matters — and understanding where delay comes from is the first step to reducing it.
This calculator breaks down total input-to-display latency by summing its four components. Most gamers blame "lag" on their internet, but frame time and display response often contribute more total delay than network ping. A 60 FPS game inherently adds 16.7ms of frame time — twice the ping of a good internet connection.
Optimizing total latency requires addressing all four components. A 10ms ping means nothing if your display adds 20ms and your frame time adds 16ms. This calculator reveals your total delay budget and identifies the weakest link to prioritize for improvement.
Gamers, streamers, and content creators benefit from precise gaming latency impact data when optimizing their setup, planning purchases, or maximizing performance and value. Bookmark this tool and return whenever your hardware, games, or streaming requirements change.
Gamers spend hundreds on low-latency routers while ignoring 20ms of display lag. Total latency is a chain — every link matters. This calculator identifies which component contributes the most delay so you can invest in the upgrade that actually reduces total lag. Instant results let you compare different configurations and scenarios quickly, helping you get the best performance and value from your gaming budget.
total_latency = ping + frame_time + input_lag + display_response frame_time = 1000 / fps Where: ping = network round-trip time frame_time = time to render one frame (1000/FPS) input_lag = mouse/keyboard polling + processing delay display_response = monitor pixel response + processing time
Result: 38.9ms total latency
With 25ms ping, 6.9ms frame time (144 FPS), 2ms input lag (1000Hz mouse), and 5ms display response (fast IPS monitor), total latency is 38.9ms. Network ping is the largest contributor at 64% of total. Upgrading to fiber (10ms ping) would reduce total latency to 23.9ms.
Latency in gaming is a chain of sequential delays: your input device sends a signal (1-8ms), the game engine processes it and renders a frame (4-17ms), the frame travels over the network (5-50ms), and the monitor displays the result (1-25ms). Each link adds up.
Frame time is often the largest controllable latency source. At 60 FPS, each frame takes 16.7ms. At 144 FPS, 6.9ms. At 240 FPS, 4.2ms. Pushing higher frame rates — even beyond your monitor's refresh rate — reduces input lag because newer frames are always available for display.
Network: Use wired Ethernet, enable QoS, choose a close game server. Frame time: Lower graphics settings, use DLSS/FSR, cap at monitor refresh rate. Input: Use a 1000Hz+ mouse, enable NVIDIA Reflex. Display: Enable game mode, use a low-response monitor, choose 144Hz+ refresh rate.
Under 40ms is excellent for competitive gaming. 40-70ms is good for most online games. 70-100ms is playable but noticeable. Over 100ms feels sluggish in fast-paced games. Casual and single-player games are comfortable up to 100-150ms total.
It depends on your setup. For most gamers, frame time (FPS-dependent) and network ping are the two largest contributors. On a 60 FPS setup with decent internet, frame time dominates at 16.7ms. On a 240 FPS setup, network ping usually dominates.
Yes. A fast 1ms response time monitor saves 4-20ms compared to a slow 5-25ms panel. More importantly, a high refresh rate monitor (144Hz+) reduces frame time. A 144Hz monitor refreshes every 6.9ms vs 16.7ms for 60Hz — a 10ms improvement.
NVIDIA Reflex is a technology that reduces internal rendering pipeline latency by synchronizing the CPU and GPU work queue. It typically reduces system latency by 10-30ms in supported games. It's free and available on GTX 900 series and newer GPUs.
A 1000Hz mouse polls every 1ms vs 8ms for 125Hz. That's a 7ms difference — meaningful in competitive gaming. For keyboard, higher polling rates (e.g., 8000Hz on some gaming keyboards) offer diminishing returns beyond 1000Hz for most players.
Calculate which adds more latency. If you're on 60Hz (16.7ms frame time) with 10ms ping, upgrading to 144Hz saves ~10ms. If you're on 144Hz with 50ms ping, better internet saves more. Use this calculator to identify your bottleneck.
