Many players have posted on Reddit and elsewhere asking for ways to fix Roblox lag. For example, this is what one such player said, “Roblox on PC has been so laggy lately… I’ve been getting constant frame drops, lag spikes, you name it.” Roblox lag causes stuttering and slowdowns, amounting to very awkward or almost unplayable gameplay. Such lag can be network, graphics, or system-related. This is how players can fix Roblox lag on Windows PCs.
Reduce Graphical Settings
Reducing graphical settings is one of the best ways to fix graphics Roblox lag, which is a potential resolution the game’s support service recommends. Roblox includes an in-game setting with which you can reduce graphical quality. You can reduce the Graphics Quality setting for a Roblox game like this:
- First, start a Roblox game.
- Press the Esc key.
- Change the Graphics Mode option to Manual.
The Graphics Quality option
- Reduce the Graphics Quality setting to the lowest bar.
Clear the Temp Folder
Some players confirm that clearing the Temp folder can fix Roblox lag. Roblox will regenerate fresh assets after you clear the Temp folder. This is how you can clear temporary file data:
- Click Start with your mouse’s right button to select Run.
- Input %temp% into Run and click on OK.
- Press Ctrl + A to select all files in the Temp folder.
- Click on the Delete option in File Explorer.
The Temp folder
- If a File in Use prompt appears, select the Do this for all current items checkbox.
- I also recommend clearing the Recycle Bin when applying this potential fix. To do so, right-click the Recycle Bin on the desktop and select Empty.
Disable Cameras
Some players say they’ve fixed Roblox lag by disabling cameras. Most laptop users will at least have built-in cameras on their PCs. Note that you’ll need to re-enable the camera if you want to utilize it again. This is how you can turn off cameras in Windows 11:
- Click the Search box within the taskbar.
- Input a manage cameras into the search box.
- Click the matching Manage cameras search result.
- Next, click the connected camera on your PC.
- Select the Disable option.
Camera settings in Windows
- Repeat the previous two steps to deactivate all your PC’s cameras.
Close Background Apps
Too many background apps running can cause system-related Roblox lag. To remedy this potential cause, try closing unneeded third-party background apps before playing Roblox. You can close background apps like this:
- Press Task Manager’s Ctrl + Shift + Esc key combination.
- Right-click third-party background apps and processes on the Processes tab and select End task.
- To disable apps from automatically starting with Windows, click the Task Manager Startup tab. Then right-click startup items to select Disable.
The Startup app tab
- In addition, right-click the icons for apps in the system tray of the taskbar to select options that close them.
Select the High Performance Power Option
The Balanced and Power saver options can potentially cause some degree of Roblox lag when selected. If one of those options is set on your PC, try selecting the High performance option instead. These are the steps for selecting that option.
- Open your Run dialog.
- Enter powercfg.cpl in Run and select OK.
- Click the High Performance radio button.
The High Performance option
Select the High Performance Graphics Option
If your PC has dual graphics cards, select the High performance option for Roblox. High performance is a Windows option that sets a game to utilize a dedicated AMD or NVIDIA graphics card rather than an integrated alternative. This AMD page tells you how users can select the High Performance setting in Windows for specific games. You will need to select that option for the RobloxPlayer.exe file in the C:\Users\%UserName%\AppData\Local\Roblox\Versions\[Latest_Version_Folder] folder location.

Other Possible Ways to Fix Roblox Lag
If Roblox still lags too much after applying the possible remedies above, there are more potential resolutions you can try. Try applying these additional potential fixes for Roblox lag:
- Update your PC’s network drivers with Driver Booster 13.
- Set a Google DNS with the 8.8.8.8 preferred and 8.8.4.4 alternative addresses.
- Select the Disable full-screen optimizations option for the RobloxPlayer.exe file.
- Disable all superfluous Windows visual effects via the Performance Options window.
I hope some of the troubleshooting methods above fix the Roblox lag on your PC. There might not be a surefire way to fix Roblox lagging, but the potential remedies above have worked for some players. So, applying them might at least reduce the lag in your Roblox game.
