How to fix Roblox lag on different devices

Roblox is an online community platform that lets you code and create your own games, and play games made by other users. Some players are plagued by Roblox lag spikes caused by a slow internet connection or a device that's running too many programs. However, ISP throttling is the most common cause and involves your internet provider slowing down your internet speeds.

The most effective way to reduce lag on Roblox is to use a VPN. Connect to Roblox with a VPN, and you’ll anonymize your connection – this prevents your ISP from slowing down your connection. If you’re looking for a guide or can’t seem to fix your Roblox lag spikes, take a look at the instructions below.

Why is Roblox so slow and laggy?

There are three different types of Roblox lag: network, graphic, and system lag. Each of these can cause effects on your gameplay, such as slowed-down frame rates, rubberbanding, and low-quality screen resolution.

• Network lag: This is caused by a slow connection, which can include poor-quality internet services or ISP throttling.
• Graphic lag: If your device doesn't have a powerful enough graphics card to run Roblox on your chosen graphical settings, you’ll likely see the effects of lag.
• System lag: This can occur when your computer is running too many applications at once or has become bloated with useless files, and Roblox uses up all your remaining CPU/RAM.

7 key steps to stop Roblox lag

You can typically get past Roblox lag and enjoy the game again by figuring out the cause of your lag and resolving it. Following hours of in-house tests, I recommend trying the following 8 steps to stop Roblox lag spikes:

1. Check your internet connection. Since lag can be caused by a slow internet connection, start by checking your internet speed on speedtest.net. Roblox recommends between 4-8 Mbps minimum to play without lag.
2. Close all high-power applications. If you’re running other applications that hog system resources, close them before trying Roblox again. Ideally, try running Roblox as the only application you have open.
3. Lower your graphics settings. As gamers, we all want to use the best graphics possible; however, if your device can’t handle Roblox on “Maximum,” try stepping down to “Very High” or “High” to see if there’s a noticeable difference in your lag.
4. Check Roblox is up to date. While Roblox updates automatically, it can stop doing so in some cases. Go to your account and log in on the Roblox website, then click the settings icon and look for an “Update” option to make sure your game isn’t outdated.
5. Check your device is up to date. Similarly, running old operating system software can cause apps to be more sluggish. Check whether your device is up to date in your device’s settings menu and install any updates available. This has the double benefit of ensuring that your device is secure against malware vulnerabilities.
6. Make sure low-power mode is disabled. Low-power mode prioritizes system resources in a different way to usual, which can cause apps to run more slowly. Check that Windows Battery Saver and Mac Low-Power Mode settings aren't switched on by clicking on your battery icon.
7. Reboot your device. Restarting your device can help to clear out background processes and free up system memory, particularly if you’ve recently uninstalled old applications.

If none of these steps seems to have solved your problem, there’s a catch-all solution you should try. The best way to fix Roblox lag is to use a reliable VPN. If you connect to a VPN and re-run your speed test, you’ll also be able to tell if your ISP is throttling you, as your speed will increase. A VPN anonymizes your connection so that you can’t be throttled. During my in-house tests, NordVPN proved best at ensuring a stable, lag-free connection to play Roblox on any device.

Why is Roblox so laggy on my computer?

Playing Roblox on a computer opens you up to more potential pitfalls that can cause Roblox lag spikes. The most common cause for all devices is ISP throttling, which can be solved with a VPN. However, you could also be lagging due to outdated hardware or software, a bloated cache, or other applications running in the background. Figuring out the problem can be simpler if you consider what factors may be affecting you.

For example, if you have a high-end gaming computer, then the problem is less likely to be a result of your graphics settings being too high or your graphics card struggling to keep up. Similarly, if you run a speed test on your internet connection and receive strong results, it’s unlikely to be the quality of your connection. That said, getting a premium Roblox VPN like NordVPN can resolve many of the issues that cause lag on Windows. Below, you’ll find steps to make Roblox less laggy on Windows and Mac.

How to make Roblox less laggy on Windows and Mac

Based on in-house testing, I was able to resolve my Roblox lag spikes by going through a number of steps for both Windows and Mac devices:

1. Get a VPN to mask your internet usage. I successfully reduced lag with NordVPN – now 76% OFF.
2. Connect to the internet by ethernet cable. Wi-Fi is generally slower than a wired connection. I always experience lag spikes when using remote play if my console’s connected to Wi-Fi. Make sure you plug in an ethernet cable.
3. Clear your Roblox cache. If you’re playing a lot of Roblox games, your cache can become cluttered. Clear it on Windows by going to AppData\Local\Roblox. On Mac, it can be done by pressing Command + Space Bar to open spotlight, then entering the following command:
4. Enable High Performance mode on Windows. This can be done in the Windows Control Panel under System and Performance Options settings.

Why is Roblox so laggy on my gaming console?

The causes of Roblox lag on gaming consoles are similar to those experienced on a computer. However, there are also factors specific to your console that can cause lag:

• Remote play: I often use remote play to stream games from my PS5 to my Mac. However, I’ve noticed frequent lag spikes by doing so. Avoid remote play if you’re experiencing lag on Roblox.
• Low system resources. Unlike PC gamers, console owners have no control over your console’s CPU power and RAM, but you can try adjusting your game’s graphical settings to see if it helps.
• Background apps. PS5s can’t run two games at once, but if you’re streaming a game on Twitch or Screen Share, make sure they’re turned off.
• Poor network connection. As with desktop gamers, your Roblox lag spikes could be the result of a slow network connection.
• ISP throttling. If your connection is throttled, it’ll affect every device using the network, not just desktop computers.
• Server issues. Sometimes, games servers can experience issues. While you can’t resolve this, you can check if it’s the case using Downdetector.

How to make Roblox less laggy on PS4 and Xbox?

Reducing Roblox lag spikes on a PS4/PS5 or Xbox is a little simpler than with a desktop computer, as there are fewer considerations. For example, you have no control over graphical settings, and you can’t typically run multiple applications at the same time as your console will close previous games when you boot up Roblox.

Here’s a quick guide to clearing your PS5’s cache, as the process isn’t particularly obvious:

1. Turn off your PS5 completely. Avoid using rest mode – make sure that the system switches off and the light goes out.
2. Hold down the PS5 power button. Wait until you hear two beeps.
3. Connect your PS5 controlled via USB and press the PS5 button. This will bring your console into Safe Mode.
4. Select Clear Cache and Rebuild Database.
5. Now, you can reboot your PS5. Consoles can still get clogged up with background processes, so going through these steps could help resolve Roblox lag issues.

Note that gaming consoles don’t natively support VPN software. However, you can easily enjoy the benefits of a VPN on your Xbox or PS4/PS5 by installing a VPN directly on your router. This has the added benefit of protecting all the other devices in your household that are connected to that network.

Why is Roblox so laggy on mobile?

Roblox lag on mobile devices doesn’t tend to have the same array of causes that you’ll face on a PC or Mac. This is because you have no choice over your device’s hardware and processing power. Roblox lag on mobile can be caused by low battery power and out of date mobile software. Low-power battery modes reduce the available processing power for games because they’re designed to conserve energy. Outdated software can cause conflicts with newly-released versions of an application, leading to worse performance.

Your choice of network can also play a part. While your desktop device is typically connected to a speedy home network in most cases, Roblox mobile lets you play games on the go. So, if you’re trying to play on a 3G connection or sluggish public Wi-Fi connection, you’re more likely to face problems with lag on Roblox.

How to make Roblox less laggy on mobile (Android and iOS)

If you tend to play Roblox on an Android or iOS smartphone, the best solutions to try vary slightly from desktop users. Here are the most immediate solutions you should try:

1. Check your battery levels. When your battery is low, your device can enter a low-power mode that reduces available system resources, so keep it topped up.
2. Update your phone’s software. Running an outdated mobile OS can result in performance issues, so check that your device is up to date.
3. Play on a fast network. Free Wi-Fi networks tend to be slow and unsupportive of demanding games. If you use Wi-Fi, make sure it’s a fast, stable network.
4. Use a VPN on Wi-Fi. If you’re using your home Wi-Fi network, you can still be throttled by your ISP. Even if you’re on a public Wi-Fi network, it’s best to use a VPN so that you’re not exposed to the cyber threats of unsecured networks.

VPN doesn't solve Roblox ping issues: common reasons and solutions

Your choice of VPN server could be hampering your connection speed and causing lag – choose a server that’s in close proximity to your Roblox server to reduce the network routing distance and lower your ping. You'll find your Roblox server by looking at the Servers section of the experience page on their website and looking at the server connected to the game you’re playing.

However, if this still doesn’t solve the problem for you, there are additional steps you can try:

1. Try a dedicated gaming server. NordVPN and other premium VPNs offer dedicated gaming servers that are optimized for fast, responsive connections that reduce ping.
2. Connect to an alternative server. If choosing a server close to your Roblox server hasn’t helped, choose one that’s in close geographical proximity to you instead.
3. Upgrade your VPN subscription. Many users try a free VPN first, but they hamstring your speed and have sub-par connections compared to paid VPNs. Most premium VPNs offer free trials and money-back guarantees to test if it works for you – free.
4. Choose a different VPN provider. In my in-house tests, NordVPN, Surfshark, and TotalVPN could all reduce and prevent Roblox lag spikes. Consider switching providers if you’re trying an ineffective VPN.

Final thoughts on effective ways to fix lag on Roblox

Roblox can lag for a variety of reasons, including outdated hardware and software, a poor internet connection or ISP throttling, a Wi-Fi connection over an ethernet connection, and a bloated device with numerous applications running. Some quick fixes you can try include clearing your device’s cache to free up system resources; connecting your device to the router via an ethernet cable; updating your OS and Roblox software; and ensuring your device is plugged into power. Failing that, be sure to use a VPN if you want to avoid the most common cause of Roblox lag – ISP throttling. This also ensures the most efficient data routing path between your device and the Roblox servers, particularly when you choose a VPN server located in close geographical proximity. I recommend choosing NordVPN as it showed the fastest lag-free connections during my in-house tests.

Does VPN reduce lag in Roblox?

Yes, a VPN can reduce lag in Roblox if your ISP is throttling your connection. It can also help by reducing the routing path for network data between your console and the gaming servers. In my in-house tests, NordVPN was able to resolve low Roblox frame rates and led to a smoother experience. Test it yourself with NordVPN’s 30-day money-back guarantee.
