Try these fixes:

You might not have to try them all; simply work your way down the list until you find the one that works.

But before diving into troubleshooting, it’s recommended that you restart your PC and access the game again. Some lags on Roblox are easily resolved by simply restarting the game.

Fix 1: Close unnecessary programs

The game lagging is generally a sign of a slow game. This can be caused by having too many high-power programs using your system resources. For the most optimal experience, it is recommended that when you run Roblox, you close those other programs. To do this, take these steps:

1. On your keyboard, press the Windows key and X at the same time to select Task Manager.
   
   
2. Select each resource-hogging application and click End Task to close them one by one.
   

Try to launch Roblox again to see if it stops lagging now. If the problem remains, please move on.

Fix 2: Delete temporary files

Temporary files created by Windows or programs you use could take up some hard drive space, which slows down your computer. So to make your computer and the programs run smoother, you should delete those temp files. Here’s how you can do this:

1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.
2. Type %temp% and then press Enter on your keyboard.
   
3. Delete all the files in the temp folder. (Press Ctrl and A at the same time to select all the files. Then right-click and select Delete.)
   
4. If a window pops up saying that The action can’t be completed, simply check the box Do this for all current items and click Skip.
   
5. Now go to your Recycling Bin from your desktop. Right-click on it and select Empty Recycle Bin.
   
6. Click Yes.
   

After deleting the temp files, launch Roblox to check if the lag is reduced. If the problem persists, proceed to the next fix.

Fix 3: Update your network driver

When your Roblox is lagging, it’s generally a sign of a slow connection. Your outdated network driver can be the culprit and make your game super laggy. To fix it, you need to update your network driver, especially if you can’t remember when you last updated it.

How to update the network driver

You can manually update your network driver by going to the manufacturer’s official website to download and install the correct network driver for your system.

OR

You can do it automatically with Driver Easy. It’s a useful tool that will automatically recognize your system and find the correct driver for it. With Driver Easy, updating drivers is just a matter of a few clicks.

See if you can launch Roblox now. If the problem persists, please move on.

Fix 4: Use a wired connection

For gaming purposes, a wired connection is preferable over a wireless connection. Wireless connections are most susceptible to interference and aren’t as consistent as wired connections. More importantly, they increase latency. Therefore, if possible, use a wired connection when you play a game online.

However, if you don’t have access to the wired connection, don’t worry, you can check out other fixes below.

Fix 5: Change your DNS settings

Sometimes your ISP-supplied DNS server might be slow or not properly configured for caching, which can slow your connection a little bit. And that might be the reason that your Roblox is so laggy. To save you time troubleshooting, you’re supposed to change your DNS settings. Here we recommend the DNS addresses from Google:

1. On your taskbar, right-click the network icon, then click Open Network & Internet settings.
   
2. Click Change adapter options.
   
3. Right-click the network you’re using, then click Properties.
   
4. Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
   
5. Select Use the following DNS server addresses, fill in the Google DNS server addresses as below, then click OK.
   
   Preferred DNS server: 8.8.8.8
   Alternate DNS server: 8.8.4.4
   
   
6. Launch Roblox again to see if it still lags. If so, please move on.

Fix 6: Reduce the graphics quality

Intense in-game graphics settings could also make Roblox lag, especially if your graphics card and processor are not very advanced. In this case, to reduce the lagging problem, you can reduce the graphics quality as follows:

1. Launch any Roblox game.
2. Select a Roblox game and click on the Play button.
   
   If you haven’t installed the Roblox Player, a window will be popping up on the screen. Just click Download and Install Roblox and then double-click on the installation file to install it.
   
3. Press ESC on your keyboard and on the upper left corner of the screen, you’ll see the three-line tab. Just click it.
   
4. Click the settings tab. In the Graphics Mode section, click the next > arrow to change it to Manual. Doing so will enable you to adjust the graphics quality by yourself.
   
5. In the Graphics Quality section, click the button with the minus sign (-) to lower the graphics quality.
   
   After that, click Resume Game to return to your game.
   

Fix 7: Delete the textures folder

To speed up Roblox on your computer, you should delete the textures folder. Without textures, the game should run a little bit smoother.

To do so:

1. Press the Windows logo key and type Roblox player, then Open file location.
   
2. Right-click the execution file for Roblox Player and select Open file location again.
   
3. Click PlatformContent.
   
4. Click the PC folder.
   
5. Click the textures folder.
   
6. Delete all the other folders except for these: grass, sky, water, and the dds files.
   

After taking all the steps, play a Roblox game. You’re supposed to be able to have your game performance improved.

Fix 8: Disable fullscreen optimizations

Windows sometimes causes performance issues by trying to optimize games running in fullscreen. This feature can lead to stuttering or slow performance in some cases. Turning it off may help improve smoothness and reduce lag in Roblox.

To disable it, follow the steps below:

1. While Roblox is running, open the Task Manager by pressing the Windows logo + R keys simultaneously, then type taskmgr.
   
2. Right-click on the Roblox process and select Properties.
   
3. Select the Compatibility tab. Check the box next to Disable fullscreen optimization. Then click Apply > OK.
   

After applying the changes, test your gameplay.

Fix 9: Repair system files

Over time, important system files can become corrupted or go missing, which can lead to performance problems. Using the System File Checker tool in Windows can scan for any missing or corrupted files and automatically restore them. To do this, To do this, open Command Prompt as an administrator, type sfc /scannow, and hit Enter. Let this scan run, and it will check your system files against a cached copy and replace any that are damaged.

Once done, restart your machine and check if it fixes your issue.

Hopefully, this post could help you reduce Roblox lag and you can have a better gaming experience! If, unfortunately, all else fails, you should consider reinstalling Roblox.
