Top 5 Tips to fix Overwatch Lag

Overwatch is easily one of the best competitive games released in recent years, but when lag hits, the disadvantage you have against other players makes the game a whole lot less enjoyable. To help you, here is a guide that will cover the best ways to fix Overwatch lag using the tools at your disposal.

Overwatch Lag Fix Guide

1. Server status

In some cases lag can be caused by the servers themselves. In which case there is nothing you can do about this except stay informed to see when the issue has been resolved. The best place to keep an eye on is the official Blizzard Twitter.

2. System Requirements

If your console’s hard drive is full it can run sluggishly. If you’re playing on a PC then it needs to be of a good enough specification in order to handle the game.

What you need to do:


A. Delete some of the games/applications on your hard drive to free up space.

B. Replacing the built in hard drives with SSDs (a much faster storage device than traditional hard drives) can rapidly speed up loading times. A Google search will throw up several options. Though this can be expensive and is not for everyone.


A. Check the minimum PC specifications match your rig.

B. If you only just meet the requirements and you’re still experiencing stuttering/lag then you may need to reduce the games graphical settings in order to aim for 60FPS or 30FPS at a minimum. Stop any intensive background programs as these could be causing stuttering and FPS drops.

3. Wired > Wireless

Playing on WiFi is NEVER good for gaming. It can be unstable and cause lag spikes, packet loss, jitter etc – basically it can cause a whole heap of headaches. If you are serious about reducing your Overwatch lag then playing on a wired connection is an essential step.

What you need to do:

Currently playing wirelessly

A. Switch to wired connection. Connect an ethernet cable from your console / PC to your router. If the two are far apart you can buy long ethernet cables (some are as long as 100 metres) to link the two.

If you can’t run a cable between them then look into Powerline adapters, which is a very clever gadget that allows you to use your house’s electrical wiring to transport an ethernet connection around your home. Just plug one end into a plug socket near your router and the other in a socket near your console and you’re good to go. Magic. Check them out:

B. If you HAVE to play wirelessly then there are a few things you can do to improve it’s reliability:

– Connect to your router’s 2.4GHz frequency instead of 5GHz as it is more stable. All wireless routers have a 2.4GHZ frequency. If you are not sure which frequency you are connected to then check your router’s WiFi settings.

– Use a WiFi analyser to find the least congested channel in your area and then change to that in your router’s WiFi settings.

Already wired

A. If you’re already playing wired then you may want to switch out your ethernet cables as they can degrade and become faulty over time.

4. Open NAT

You can have connection issues if the ports required for the game are not open, meaning you don’t have an ‘Open NAT’. A strict or moderate NAT can cause you to be unable to connect to other players online.

What you need to do:

A. Check your NAT status. Do this by going to the network settings on your console. Unfortunately for PC players the game doesn’t tell you this and there is no easy way to check – move on to the next step to ensure you’re able to connect to other players.

B. If you do not have an open NAT then you should enable ‘UPnP’ on your router. This will automatically open the necessary ports for you. If you still don’t have an open NAT after trying this then then you can manually port forward yourself. Just make sure to do one or the other. Activating both can result in conflicts.

5. Bandwidth & Local Congestion

I’m sure you have heard someone say this before at least once:

“I’ve just upgraded my Internet speed to X billion megabits per second so I’m now going to be unstoppable online”?

Yeah? Thought so. This is one of the biggest myths in gaming. High bandwidth speeds do not mean you will have a faster gaming connection.

The truth is games only need a little bandwidth, usually less than 0.5mbps and Overwatch is no exception. When it comes to bandwidth speeds what actually matters is congestion on your line, which is caused by other people in your home hogging the bandwidth e.g. when they stream a HD film or download a torrent. This creates gridlock on your Internet connection and will cause your game to lag significantly.

What you need to do:

A. Most routers have a feature called ‘QoS’, which is designed to prioritise the traffic on your network, e.g. gaming over other applications, and / or eliminate congestion. But most routers do a very poor job of this as they rely on technology that is outdated and ineffective.

At Netduma we invented a unique algorithm that will totally eliminate all congestion, meaning you can game whilst everyone else uses the Internet as much as they need to. Check out a demo of this in action:
