If Roblox is struggling to run cleanly, other games appear to be perfectly fine, and your web browser isn’t buggy when you surf the net, it’s safe to assume your Roblox settings are the issue. [2] X Research source

Hop back into the game to see if your lag is gone. The game won’t look nearly as good as it used to, but that will free up computing space to make the game run more smoothly. If the game is still buggy but you try every other solution out there, try reinstalling the game. It’s possible a game file was corrupted or something along those lines.

If offline games are also laggy, changing your PC settings should dramatically improve your performance. Just FYI, if your computer is showing that you’re near 100% CPU, memory, or disk, your computer is either damaged or incapable of handling the game you’re playing. If you find yourself needing to do this every time you boot up your computer, disable unnecessary startup programs.

If you have a graphics update that you haven’t installed, it may cause Roblox to run poorly or lag occasionally. Updating the graphics may solve your problem.

Plug your laptop in if you’re going to use the high-performance setting while playing. This is going to drain your battery pretty quickly if you aren’t plugged in.

Most modern PCs will defrag the hard drives automatically, but you may not have this setting turned on. Over time, the data on a hard drive can get split up into all kinds of subfiles and temp folders. Defragmenting the drive cleans up all of those messes so that your computer runs faster.

Your internet is likely the problem if you notice that other online games are buggy and slow.

Also, turn off any smartphones, tablets, video game consoles or video streaming devices that are connected to your network.

A bad Wi-Fi connection is probably the most common reason online gaming lags randomly. This is almost certainly the issue if your ping and lag spikes appear out of nowhere and then go away minute or two later.

You may need to ask your parents about the internet speed your family is paying for before running the test.
