Delay in Games: What Causes it and How to Fix

Delay in games is one of the most frustrating things a player can experience.

You press a button expecting something to happen immediately, but instead, there's a noticeable pause, your character moves too late, your shot misses, or your ability goes off after the enemy is long gone.

Whether you're into competitive shooters, MOBAs, MMOs, or even casual games, delay can ruin your experience and even cost you the match.

But what actually causes this delay? And more importantly, what can you do to fix it? In this article, we'll break down the different types of delay in games, what causes each one, and how you can reduce or eliminate them.

What Types of Delay in Games You May Have?

Not all delay is the same, and understanding what kind you're dealing with is the first step toward fixing it. In general, delays in games fall into two categories: input delay and network delay.

Input Delay

This is when there's a noticeable lag between pressing a button or moving the mouse and seeing that action happen on-screen. Input delay usually has to do with your local setup, like your monitor, peripherals, and computer settings.

Network Delay (a.k.a. Latency or Lag)

This happens when the data from your device takes too long to travel to the game server and back. You might press a key to use a skill or shoot, and the game reacts too slowly or not at all.

This type of delay is usually related to your internet connection, the game's servers, or even the route your data takes to get to its destination.

What Causes Delay in Games?

Causes of Input Delay

Let’s start with what’s happening on your side:

• Low refresh rate monitors: If your monitor is running at 60Hz, you're only seeing 60 frames per second. That means there's always some delay in what you're seeing versus what's happening.
• High frame times / low FPS: If your computer struggles to maintain stable frames per second, your inputs won’t feel responsive.
• V-Sync enabled: While it prevents screen tearing, V-Sync can introduce noticeable input lag.
• Wireless peripherals: Bluetooth keyboards, mice, or controllers can introduce minor delays compared to wired ones.
• Display processing: Some TVs or monitors apply image processing (like motion smoothing), which adds latency before displaying the signal.
• Outdated or bad drivers: GPU, mouse, and keyboard drivers may all affect responsiveness.
• Background processes: High CPU or RAM usage from other programs can cause delayed input processing.

Causes of Network Delay

This is where things get more technical. Network delay happens at various points between your PC or console and the game server:

• Packet size and prioritization: When you click to use a skill, that action is sent as a data packet. It travels the same route as your movement input but tends to be larger. Some routers prioritize smaller packets and push your skill command to the back of the line.
• ISP-level QoS: Your Internet Service Provider may classify game traffic separately from regular data traffic, causing shifts in priority. Gaming packets might get deprioritized in favor of streaming or voice calls.
• Overloaded routers: If your home or ISP router is under heavy use, say from video calls or streaming, your gaming packets can get stuck behind others.
• Packet loss: If a packet is lost along the route, it has to be resent. That resend introduces delay. Worse, if it happens frequently, gameplay becomes choppy or even unplayable.
• Bufferbloat: This happens when your router queues too many packets before sending them out. Your gaming packet might be stuck behind a hundred Netflix chunks.
• Dynamic routing: Sometimes, the path your packet takes to reach the server changes mid-game. If the new route is longer or more congested, delay increases.
• DDoS filters: During a DDoS mitigation event, filters that inspect extra packet headers may slow down legitimate game traffic.
• Corporate firewalls: Some networks insert small pauses (micro-lags) when reviewing large UDP packets, which games often use.
• Weak wireless signal: A bad Wi-Fi connection leads to packet retransmissions. The device keeps sending the same packet until it gets a confirmation, introducing delay.
• DNS issues: A poor DNS configuration can cause your connection to take a longer-than-necessary path to the game server.
• Overloaded game servers: Sometimes it’s not your fault. If the server is overwhelmed, it builds a queue to handle incoming actions, which delays response time.
• Packet dependencies: If a single skill requires multiple packets and one gets delayed or lost, the whole action waits for it.
• BGP route changes: Border Gateway Protocol can reroute your traffic from a fast path to a slower one without warning.
• Out-of-sync animation/audio: When network delay exceeds the skill’s animation time, it creates desync between what you see and what actually happened. It feels like the command was skipped or eaten.

How Can You Fix Delay in Games?

Fixes for Input Delay

Improving input delay is often about upgrading or optimizing your local setup:

• Use a high refresh rate monitor (at least 120Hz): This gives you smoother and faster feedback on-screen.
• Turn off V-Sync or use G-Sync/FreeSync properly: They reduce tearing without adding as much latency.
• Update your drivers regularly: Make sure your GPU and peripheral drivers are up to date.
• Use wired peripherals: They’re more responsive and reliable than wireless alternatives.
• Enable Game Mode on monitors/TVs: This disables image processing that adds delay.
• Close background apps: Free up system resources so your game gets priority.
• Lower in-game graphics settings: This helps maintain a higher FPS, which improves response time.

Fixes for Network Delay

Now let’s deal with the trickier part: your connection to the game server:

• Use a wired Ethernet connection: Always better than Wi-Fi, which is vulnerable to interference and weak signals.
• Limit bandwidth usage at home: Pause downloads, streaming, and other high-traffic apps while gaming.
• Configure Quality of Service (QoS): On some routers, you can prioritize gaming traffic manually.
• Change your DNS to a faster provider: Use Google DNS (8.8.8.8), Cloudflare (1.1.1.1), or another known provider.
• Restart your modem/router regularly: Keeps your home network running smoothly and clears up minor issues.
• Avoid peak gaming hours if possible: Servers and ISPs can get overloaded at night or on weekends.
• Check server status: Sometimes the problem isn’t on your side. If servers are lagging, there’s little you can do but wait.
• Talk to your ISP: Some ISPs may be able to improve your routing or move you to a gaming-friendly plan.
• Test different servers if the game allows: Choose the one with the lowest ping, even if it’s not geographically closest.
• Use NoPing: NoPing reroutes your connection using optimized pathways, reducing ping, packet loss, and jitter. It avoids congested paths and helps your traffic reach the game server faster, with fewer delays.

Here’s how to use NoPing to fix delay in online games:

• Sign-up through the website and download NoPing (you can test it for free).
• Open NoPing and search for your game inside the software

• Once you find it, click on it and, on the next screen, select “Choose automatic” or “Choose manual” and click “Continue”. We recommend choosing automatic, as NoPing’s technology analyzes all routes on a global scale and automatically selects the best option for you.

• On the next screen, click on “Optimize Game”.

• And that’s it, you can start playing with optimized ping!

You can test different servers within NoPing to see which gives you the lowest latency.

What’s the difference between lag and delay?

They’re often used interchangeably, but “lag” usually refers to network delay—when data takes too long to travel between your device and the game server. “Delay,” on the other hand, is a broader term.

It can refer to input delay (when your actions take time to register due to hardware or software issues) or network delay (when the connection itself is the bottleneck).

So, if your mouse feels sluggish or your character reacts slowly even offline, that’s input delay. If your shots register late or enemies teleport around online, that’s lag (a type of delay caused by the network).

FAQ

Why do I only have delay in certain games?
Different games use different servers, engines, and netcode. Some are better optimized than others.

Does using a VPN help reduce delay?
It can in some cases, but not all VPNs are built for gaming. NoPing, for example, is specialized in reducing gaming latency.

Can a gaming router reduce delay?
Some routers are optimized for gaming traffic and offer features like QoS and better hardware, which can help.

Is 30ms ping good for gaming?
Yes, anything under 50ms is generally considered excellent. Between 50–100ms is decent. Over 100ms and you may start to feel delay.

Can playing on Wi-Fi cause delay?
Absolutely. Wi-Fi is more prone to interference, signal drops, and packet loss than a wired connection.

Is delay worse on console or PC?
Not necessarily. It depends more on your hardware, network, and game optimization than the platform itself.
