Among the known culprits include an outdated Windows build in use, firewall/antivirus software, internet connection problems, and memory-related issues. In some cases, buffering in Roblox may also be directly attributed to a server issue like when the game server is currently having some outages or maintenance. In worst case scenarios, buffering and lagging in PC games can be due to faulty hardware like an outdated or corrupted GPU or graphics card driver in use.

Troubleshooting Roblox buffering issue in Windows 10

Performing these solutions can help fix network lag, graphics lag, system lag in Roblox PC.

Before you proceed, make sure that your system is running the latest build or software version. If you haven’t set your computer to automatically download and install new updates, then care to check and install any new software patch.

Also don’t forget to give your system a quick restart. Note that a simple reboot can help eliminate minor software errors that caused hiccups to some apps and programs including Roblox. If the lagging issue in Roblox continues after a system restart, try the following methods to rule out other factors and underlying causes.

First solution: Optimize/refresh your Internet connection.

Roblox buffering can also be due to network lag on the system. To rule out network lag from the underlying cause, optimize or refresh the internet connection on  your computer using any of the following methods.

  • Disconnect then reconnect Wi-Fi. This is the simplest way to refresh your computer’s Wi-Fi connections. It’s like giving a quick breather to the Wi-Fi network and internet-based programs. Just click on the Wi-Fi icon at the bottom right corner of the status bar and click on your Wi-Fi network. Then, click the Disconnect button for your Wi-Fi network. After a few seconds, click Connect and wait for the internet connection to stabilize.
  • Forget/re-add Wi-Fi network. Forgetting or deleting the Wi-Fi network is also a potential solution to network lags that are attributed to a corrupted network. Deleting and re-adding the network will allow you to set up Wi-Fi and connect to it like the first time. Just click on the Wi-Fi icon on the status bar then right-click on your Wi-Fi network. Select Forget from the menu options. After forgetting the network, add and set up the Wi-Fi network as new.
  • Power-cycle modem/router. This can be the ultimate solution to various types of internet problems affecting a wireless network. Like other electronic devices, modems and routers also encounter firmware glitches. When this happens, internet problems such as slow internet, unstable connection or no internet occur. To fix the problem, power off the modem/router by pressing the Power button until it powers down. While it’s powered off completely, unplug its adapter from the power source then plug it back in after 1 minute. Wait for the modem light indicators to become stable and allow the computer to reconnect to Wi-Fi. Once the internet connection is stable, relaunch your Roblox game and see if the problem is gone.

If you’ve managed to set up multiple Wi-Fi networks on your computer, try to switch to another network to see if the problem is fixed. Sometimes, a corrupted Wi-Fi network in use is the root cause of the problem.

Second solution: Clear Temporary Internet files and cookies.

  • On the next screen, click on the pfirewall.log file and check for any blocked ports using the command prompt. 
  • To open the command prompt, type cmd in the Start search bar.
  • On the search result, right-click on the Command Prompt then select the option to Run as Administrator.
