What is Roblox?

Roblox, initially referred to as DynaBlocks in 2003, is an online platform that allows people to build and program their games and join games created by other users. Players can interact with one another in these video games on this platform through conversation, just like any other online group game. Roblox Corporation is the registered company behind the brand, owning and managing the website, launcher, and gaming engine used by all users to make games. According to Roblox Corp., as of June 2021, there are more than 10 million unique games on Roblox, which are played by over 43 million daily users, with 198 million active monthly users. According to the platform’s statistics, by May 2021, creators on Roblox had collectively earned over $329 million.

What is Lag in Roblox?

Roblox lag refers to delays in screen updating, chat delays, difficulty of movement due to slow screen updating, slow text updating, and the other network problems in Roblox.

Roblox lagging is how Roblox users might describe the feeling of slowed screen updating and blurred screen images when they are playing a game inside Roblox. Once an action is taken by a user inside Roblox, a request must be sent to the Roblox server. This request triggers a response and eventually leads to a new action inside Roblox. The issue of lag arises when there are delays at of any part of these processes.

To troubleshoot lagging or high latency of Roblox, one can use the in-built tool that is known as Stats. It displays the time taken to perform a variety of actions inside Roblox. If high latency is shown there, the issue is related to network connectivity such as the individual’s internet speed, security features of the router, tight bandwidth control, QoS protocols, and other similar factors inside the individual’s network.

What Causes Lag in Roblox?

Lag in Roblox games is primarily caused by a slow internet connection, underpowered hardware, poor performance of game code, or straining game server hardware. The behavior accompanying these issues is what differentiates them. Lag from network issues affects how others see you while lag from underpowered hardware affects only the player’s own point of view.

The three common types of lagging issues experienced in Roblox gaming are the following:

  1. Standard lag or slowdown: When the game is trying to retrieve information that isn’t immediately available.
  2. The infamous “Lag spikes”: Periods where the game receives an influx of information it is unable to manage.
  3. The more annoying input lag: Which occurs when the device is slow to respond to user inputs.

The actual mechanics of gameplay can create lag. For example, if code creates a situation where thousands of bricks are repeatedly being created and destroyed or other intensely resource-intensive tasks are required to progress, then lag will be experienced. If you experience lag for anything other than your local computer or network, the issue is with the code or with some aspect of the Roblox server. This is often the case with Roblox lag spikes.

How to Identify if You’re Lagging in Roblox?

You can identify if you are lagging in Roblox by entering a game and playing. If you are abruptly stopping and then suddenly moving several feet in a different direction, that is lag. Another sign is that users in chat on various Roblox forums may be discussing the game having excessive lag.

If you suspect lag, you can test your internet speed using the FCC’s Speedtest tool to get a sense of your speed relative to what your provider promises you. Semi-transparent green or red/yellow colored LOC indicators that show every player’s spatial position and database link latency under 150 show that you are not lagging in-game.

How to Fix Lag in Roblox?

  1. If the lag in Roblox is the game’s fault, waiting will eventually fix it.
  2. Reduce in-game graphics settings to lower Frame Per Second (FPS) requirements.
  3. Upgrade to a faster Wired Local Area Network (LAN).
  4. Quit cloud gaming and access Roblox on a personal device with faster single-player internet.
  5. Buy a priority gaming network that boosts bandwidth and reduces lag on multiple devices using the home network.
  6. Set in-game Display Frame Limiter to around 60 FPS to improve network performance and graphic latency if the incompatibility of the internet game provider is due to GPU usage.
  7. Firmware Update Router.
  8. Fix LAN cable.
  9. Shut off other devices that use the Internet.
  10. Adjust PC for best performance setting.

To stop Roblox lagging on your computer, use the following methods:

  1. Purge temporary files.
  2. Remove all background programs.
  3. Update video/sound driver consistently.
  4. Defragment game data drives.
  5. Implement a maintenance schedule.
  6. Hardware Upgrade.

How to fix lag in Roblox? A quote from Cody Altman, Publisher and Editorial Director of 3 Gears, a gaming website, upon being asked how to fix game lag, succinctly lays out a plan for reducing internet lag inside specifically Roblox. He recommends, upgrading our hardware, stop cloud gaming, use a priority gaming network, adjust PC performance settings, frequently update drivers, and remove any unnecessary background programs.

Check Your Internet Connection

Lag in Roblox may be caused by poor internet connection. There are many things you can do to determine the cause of internet connection issues resulting in lag on Roblox. Begin by checking on the status of your internet connection using a provider What you can do with the minimum and maximum bandwidth plan Thousandnet.

If you have bandwidth and performance issues on Roblox, make sure to check the Roblox minimum requirements for bandwidth at their website, and compare it to your connection speeds. You can upgrade your plan or contact your provider to ensure speeds are consistently fast. These measurements only matter if you are already experiencing lag, as good Roblox servers should work well even for lower bandwidth speeds.

Lower Graphics Settings

If the above recommendations have not resolved the problem, users can lower their graphics settings in Roblox. PC users can do this by pressing Esc while playing to bring up the game menu. Users can then click on the Settings gear and, on the first tab that reads Control, change the graphic quality from the drop-down menu at the top. Beyond 4 gig of graphics memory can be selected for more powerful computers but users can then choose 4, 3, 2, 1, or 0 which is the minimum and equals 1 gig, if their lag is due to a lower-spec PC that struggles with the higher levels.

Mobile users also have the same option of lowering the graphics quality in the same way as the desktop version, by tapping the 3 dots in the upper right and pressing the settings gear. The only difference is that there are fewer quality options to choose from according to the device.

Close Unnecessary Programs

Close unnecessary programs on your computer to prevent them from consuming resources while you are running Roblox. Other applications use CPU, GPU, Memory, and Disk which Roblox requires for optimal performance. Windows Task Manager is an easy and quick way to see what programs are working simultaneously with Roblox. Press CTRL + ALT + DEL and choose the Task Manager. End as many of the extra tasks as you can without affecting Roblox. If Roblox lags after you closed multiple tasks, it implies your computer running Roblox does not have sufficient hardware for Roblox or the specific game within Roblox you are playing.

Use Ethernet Cable Instead of Wi-Fi

Lag in Roblox is frequently caused by a delayed or lost network connection, which can happen with a Wi-Fi network. Unlike wired network equipment, Wi-Fi is subject to interference from other devices, making the connection weaker and sometimes unreliable. While Wi-Fi offers easy connection without wires, during times of network congestion or other network adverse circumstances, an Ethernet connection may provide more speed and reliability in ensuring stable network connectivity.

A common issue with reducing Wi-Fi lag during gameplay is how well you can receive your Wi-Fi signal. Be sure to try several internet speed tests through wired and wireless methods in order to determine the speed discrepancy between them.

There are some aspects of Network Lag that an Ethernet cable does not fix, such as if a game’s server is too far from a player and unable to provide and receive data fast enough. In such an instance then all the other causes of lag listed above must be examined before the need for better or an additional ISP is considered.

In the following YouTube video, a networking expert, Taran Van Hemert, compares his wired and wireless internet connections to show the disadvantages using Wi-Fi where greater network speed and stability is needed.

Hemert found that while his home’s Wi-Fi was able to provide a good degree of 12ms-to-18ms RTT lag, the wired internet was able to provide 8ms-to-12ms RTT latency for the same applications.

Roblox Studio Average FPS

  • Wired: 348.23 FPS
  • Wireless: 156.41 FPS

Roblox Gameplay FPS

  • Wired: 77.3 FPS
  • Wireless: 55.45 FPS

Although Roblox Studio showed a preference towards wired internet, in Roblox gameplay Hemert saw only a modest boost. Wired is useful for users asking how to stop lag on Roblox to use to eliminate the latency of connecting through a wireless signal and can reveal the true cause of their lag issues.

Measuring stop lag on Roblox in the mean time is essential while improving internet settings, network, or other parts of the equation to determine the effectiveness of these adjustments.

According to Torrentz2eu, the benefits of wired connections are that they usually provide better ping and are recommended for playing online games. Wired connections offer lower ping because of their reliability, as opposed to Wi-Fi which is influenced by electromagnetic signals. Wired networks are less likely to face server laggings like timeouts or high latency because they have better throughput, ensuring faster data packets. They have better upload and download, as well as consistent streaming. They are more reliable than Wi-Fi which can have intrusions and security issues.

According to WhoAPI, for most gamers latency is the essential aspect they need to focus on. Users with high-latency would get a better, lag-free gaming experience when using wired internet. So if you were faced with the problem of high latency while gaming in your home or the office, then to eliminate latency, wired internet is the key.

For people nowadays, wired connections may seem old-fashioned in a fast-paced modern society but making the switch still holds many advantages. Your online gaming experience may just become better growing with a wired connection. So for online gamers out there, wired connections would be the optimal way to reduce lag and improve their gaming skills.

As aptly summed up by network analyst Lawrence Systems in the following YouTube video, not all Wi-Fi is bad but it should not be considered as reliable as a wired connection – especially for getting back lost internet speed and latency that affects Roblox games.

A Roblox player, Atarii, recommends an ethernet connection to eliminate lag, citing common issues with data signal latency from WIFI like bandwidth sharing, interference, and obstacles.

To get an ethernet connection, you’ll need a modem, an internet provider, and an ethernet cable. After connecting an ethernet cable from your modem to the gaming console or computer, all the lights on your device should turn on. From here, you can manually change your devices or network to wired for minimal latency.

Additionally, in the process of learning how to stop lag on Roblox, be sure to consider the QM Cost associated with setting up a Wired internet connection. Wired requires drilling or otherwise creating holes in the walls for computer networking, as opposed to the far less labor-intensive method of laying out ca or running a cable under flooring.

Additionally, is it a good idea to get a VLAN-capable switch? VLANs help isolate network traffic, reduce latency, and improve overall network performance.

Wired internet setup Pros:

  • Decreased latency/ping
  • Increased stability/speed
  • Security
  • Operational requirements of devices without wireless capabilities
  • Freeing up WiFi spectrum

Wired internet setup Cons:

  • Expensive cabling
  • Reduced mobility
  • Potential for tripping
  • Physical damage to cabling
  • Not enough available sockets to support computers
  • Overhead costs with labor and other equipment

Wired vs Wireless (Testing Roblox Studio and Gameplay on Wired vs Wireless Connection):

  • Wired

Final Thoughts on Using Ethernet over Wi-Fi: Wired setups for home or the office where network speed and stability have to be as minimal as possible is essential for Roblox lag reductions. It is ideal to have a wireless setup and switch to wired when there are lag issues. Identifying the troubleshooting steps needed to fix any Roblox game without Wi-Fi issues and knowing when to call your ISP or IT expert, in person or online, may prevent speed reductions and eliminate lag.

The general recommendation for gamers is to use an Ethernet LAN to minimize network lag in multi-player games like Roblox. There are also 5G networks available for those who wish to stick with Wi-Fi, though this is only suited to particular buildings near service providers unless a building has an Inside 5G pack.

Connection to an external antenna means that the 5G speed is superior to that of mobile. Those in countries where 5G is just coming into use such as the UK may find speeds far below average, in which case even 4G works well for gaming and providing basic connections. However, 4G is not as good for more demanding usage, for which Wi-Fi or an external antenna is the best.

For those working in dense urban settings, a tethered cell phone would work well, provided there is an unlimited data plan which prevents unexpected high payments at the end of the month.

For those who travel, finding an international data plan specific for their region is highly recommended to stay connected and avoid roaming charges. The bottom line for how to prevent lag on Roblox is to find a connection that matches the need and surroundings of the user, such as Wi-Fi, Ethernet, or using devices to increase signals.

For example Wi-Fi extenders. An article from provides ways of reducing lag in gaming with Wi-Fi.

Did these steps solve or significantly reduce the lagging you’re experiencing in Roblox? Let me know on Twitter @quarianreal.

It is not too demanding to get cabled internet. Most internet installations are made with at least one ethernet port in every room. This means that the internet cables can be installed inside the walls or under floors. Nowadays, many homes and apartments come wired with ethernet cables leading to rooms, which is very practical for people who wish to have cabled internet. If not, then walls can be cut at some points to place the ethernet cables and then following safety measures like closing them properly.

Installation of ethernet ports for computers away from the router can be an expensive solution as it would need a professional to come and do the work. Additionally, some routers only have two ethernet ports, and additional ones could use up all the available inputs. Similarly, some devices may not have Wi-Fi connectivity, or are not compatible with Wi-Fi. A good recommendation is to look into buying a VLAN-capable switch as all devices that are connected to the internet- including telephones, thermostats, cameras, computers, smart devices, tv’s and more- are connected without any lags. Some products include the Netgear GS108T, Cisco SG100-16, and HP Procurve 1810G. Some of these switches are easy to set up, allowing QoS settings, and can even cause lag reduction for gaming when other users try to briefly reduce bandwidth when they stream or join the network.

To install a VLAN-capable switch, wireless and wired internet, you’ll need a modem, ISP contract, and VLAN-capable switch. While operating the VLAN-capable switch, make sure to pay attention when making the switch to at least some of the more important settings, such as QoS, so as to help reduce lag if your home has multiple connected devices. Make sure to note that merely switching internet connection technology is not being done. An ISP still needs to be gotten (such as from Spectrum for those in the US) with an existing internet line. The modem should be connected to the WAN port of a home router and if the home is pre-wired with Ethernet cables that lead to the rooms, then devices can be directly connected with the switch. The router is better connected to the switch. The modem should be rebooted and if the pro is active, the internet should start without any lag.

QP Cost is not a worry. The only one-time cost would be the installation of the wall ports and the purchase of the switch. The article will also note an additional one-time cost of purchasing an additional switch if the home base switch has run out of ports. There will be an additional cost of ensuring that the match-up between the device and the compatible switch is stable and that no additional fees are incurred. The only overhead cost of this setup would be installing the wall Ethernet port. Wired internet setup is the best for latency reduction, better overall performance, and stability when operating online applications requiring a strong uninterrupted connection. The pros heavily outweigh the cons when comparing latencies with various devices and testing out gaming or watching an online stream. A VLAN-capable switch is very important to complement the device’s Wi-Fi setup or when the need to resolve network speeds and certain heavy internet users who degrade the central network system arises.

Clear Cache and Cookies

A cache is a store of copies of files that are normally stored in hold or slow storage or that are only available during certain times. Cookies are data files that are stored on a user’s device during visits to websites. Both of these can slow down the responsiveness of your device and increase lag during Roblox.

Clearing your browser cache and cookies can boost the efficiency of your computer. The cache is temporary data stored by your browser, which helps it load pages faster in the future. However, it can build up over time and take up too much space, leading to slower browsing.

Clear your browser’s cache and cookies every once in a while, or simply close down your browser (make sure you have any important tabs bookmarked if you don’t want to lose them) and use it later. This is one of the possible solutions to help fix any lag problems you may be experiencing during Roblox. The steps below show how to clear the cache and cookies on three different browsers:

  • Clear Chrome Cache
  • Tap the three vertical dots in the upper-right corner of the window.
  • Select More tools > Clear browsing data
  • Select Basic or Advanced
  • Select a time span to erase.
  • Click the Clear data button.
  • Clear Firefox Cache
  • Press the Alt key to show the menu bar if you don’t see it.
  • Select History
  • Select Clear Recent History
  • Select the arrow next to Details to get rid of everything except the cache.
  • After you’ve chosen an acceptable time range, select a cleaning option.
  • Press Clear Now
  • Clear Internet Explorer Cache
  • Select Tools > Internet Options
  • Select Delete… under Browsing history.
  • Select Temporary Internet Files
  • Select Delete. Then select cookies and Cache and delete them

How to Prevent Lag in Roblox?

You can help prevent lag in Roblox by having a strong and stable internet connection as poor connections lead to latency and lower quality of connection. To prevent dropping packets while you play on a wireless network you can switch to a wired network. You can also close all unnecessary programs, apps, and file-download clients while playing Roblox, as they may use internet speed that Roblox needs to run smoothly. You can also use a service like Game Booster that changes your desktop configuration for better performance. The following settings can also be changed in Roblox to prevent lag further.

Roblox LagFix Settings

  1. Uncheck Smooth Terrain.
  2. Uncheck Advanced Graphics.
  3. Uncheck Auto-detect Graphics.
  4. Set Graphics Mode to Manual Adv.
  5. Set the Graphics to the fastest setting possible.
  6. Set Shadow Quality to 0.
  7. Set Image Quality to 4.
  8. Uncheck := Dark Outlines.
  9. Uncheck := Vignette Effect.
  10. Uncheck := Blooms.
  11. Set Resolution to 1.

Upgrade Your Internet Connection

You might be able to not lag in Roblox by upgrading your internet connection. If your internet connection is slow or not very stable, your ping may be high in games leading to lag, and decreased network stability will increase the probability of being disconnected from the game.

Having an internet connection with high Upload and Download bandwidth to the server lets your computer (and the servers running the game) send and receive a lot of data to and from each other. You should aim for download speeds of at least 16 megabits per second (2 megabytes per second) and upload speeds of at least 1 mbps (0.125 MBps) in order to not lag in the game. Anything less than this, particularly the upload speed, will typically lead to network lag. If you need help finding out what internet speed you have and which internet plans are available, you can make us of various internet speed test sites.

Use a Gaming Computer

Using a gaming computer is a sure way to not lag while playing Roblox. Regular or business computers are not designed to run resource-intensive games and have slower CPUs, less RAM, less powerful GPUs, and slower SSDs than gaming computers. These computers quickly get overburdened by the demands of running Roblox, especially if the game is processing multiple complex maps or input commands from other players simultaneously.

Gaming computers on the other hand are specially designed with the best CPU, RAM, performance GPU, and SSD money can buy which are part of minimizing lag the quick fix. Despite the disadvantage of higher prices, the better specifications allow gaming computers to process Roblox commands with ease while providing a better user experience thanks to their in-built cooling capacity and ergonomic design. To top it off, gaming computers are more resilient to cyber-attacks and are more future-proof, allowing you to use them for a long time without changing configurations just to avoid lag.

Optimize Your Computer’s Performance

Optimize your computer’s performance to not lag in Roblox. Computers that run slowly with a lot of processes running may not have the necessary resources to effectively run Roblox. Lower the load on your computer by disabling or reducing the number of apps running through the Windows advanced system settings or by using a piece of third-party software such as Advanced System Care. Also, decrease the computer’s power settings, and in the Add or Remove Programs settings uninstall programs that you do not need. Some of these settings do not directly correlate with Roblox and will need to be turned back on when not playing the game, so be sure to keep a list of the changes made so they are easily reversible when necessary.

Use a Wired Connection

If other Roblox lag-fixes do not work, consider using a wired connection for a smoother connection rather than relying on WiFi. WiFi connections tend to get lost over distances, making one’s game experience in Roblox a challenge. An easy way to improve one’s internet connection for Roblox is to simply move physically closer to the WiFi spot in the building, especially if obstacles such as brick walls are present in the building.

WiFi signals are reduced if there is a brick wall, door, or mirrors and objects with a polished surface that are located in the WiFi signal’s path. This is because these objects have a magnet effect that stops the signal. Moving your computer away from these objects will help to restore the signal loss. One can also obtain a new, higher quality, built-in WiFi system if none of these other solutions are working. Getting a ethernet adapter can also allow those with weak WiFi or stagnant speeds to experience faster gameplay. Links to the best device choices by GameRevolution are provided below to help improve one’s connection.

Keep Your Game Updated

If the reason for lag in Roblox are leaks in the code that are fixed with updates, keeping your game updated is highly important. Updating your device and clearing game storage often can also help with ensuring others’ code updates with workarounds for the game’s inefficient programming are close to the central game server and easy to work with.

Turning device background updates on is the best way to ensure your game remains updated. New updates are compatible with older game versions and regularly update in the backend. Device background data must be turned on in order for this to work even when idle. You can go into the Background App Refresh settings of your device and turn all of the apps on.


What to Do if the Lag Persists?

If the lag persists, check if you are running any other programs that require an internet connection. Other programs such as streaming applications or downloading programs that use bandwidth should be shut down since they can disrupt/permanently limit your connection. If your connection is consistently slow, the issue may be with your internet service provider (ISP) rather than the Roblox software. You can determine your current download and upload speeds using a website like “” If the speed is lower than what you are expecting (having in mind that actual download, and upload speeds tend to underperform advertised ones), check to see if you are currently close to your wi-fi router. Signal strength and stability decrease the farther you are from your router. To determine if your wi-fi connection is the issue, you can use an application such as “Wi-Fi Analyzer” which can help you identify which parts of your home or neighborhood have strong or weak wi-fi signals.


Lagging in Roblox can be reduced by getting better hardware and connectivity, playing less computationally-intensive games, and by adjusting within-game settings. Off-roading and Mad City were found to be the least lag-inducing games, while there was no lag regarding username, environment, and user level. Tools like Roblox Stats can track the Service Status of Roblox and tell users about any perceived lag within the Roblox system according to their geographical location.
