Facing lag while playing your favorite game is the worst feeling ever. Some games lag due to their high system requirements, but few of these games are fixable by reviewing and optimizing the settings.


In recent times, many players reported facing lags in Roblox.

Even with good system specifications, the game was not running smoothly. So why is Roblox so laggy? & How to fix it? In this article, we will peek into some solutions that are out there for fixing Roblox lag.

What does it mean to lag?

Lag means the difference between the time you give input in the game and the time it takes for the output to produce.

For instance, you press the forward key to move straight. But, in-game, you move 3-4 seconds after pressing the key. This delay is known as lag. It’s the most frustrating thing that a gamer goes through.

Now, let’s take a look at:

Lag in Roblox can occur due to various reasons:

Due to Network 

The lag due to the network is due to an unstable internet connection.

Even if your internet speed is high, the instability, also known as latency, should be as low as possible.

In-game, high latency or ping will make players glitch around the map. 

Due to Graphics

The graphics lag is due to the high requirements of the game, and you will experience choppy frames.


It is mainly due to your system’s low capability. With an old system, refrain from playing high graphics games.

Due to System

Another issue that causes in-game lag is heavy programs running in the background when playing Roblox.

Open Task Manager before playing Roblox & close all unnecessary applications to avoid lag.

These programs cause unwanted load on the system memory. Rightclick on the application > End Task.
