Why is Slither io So Laggy?

In Slither.io, players can experience two types of lag issue:

  • Ping Lag
  • FPS Lag

The difference is that Ping lag depends on your internet connection speed. If you have this problem, the only solution is to move closer to your router or upgrade your internet plan. To check your internet speed, visit the Speed Test by Ookla.

By contrast, players can fix FPS lag through the methods outlined below.

Select the Install button, and the page should close by itself. Now, open slither.io and refresh its page.

You will first notice that Slither’s menu has completely changed, adding many new features (and cheats, if that’s your style).

Now you’ve installed the script, select the Graphics tab. Here, change Graphics Quality to Optimized. In addition, change the Background to None (Black).

Change Graphics Quality to Low

If you are not looking to install Slither.io mods, your next best option is to change your graphics quality from high to low. This has demonstrated to make Slither io not lag on Chrome.

Although I’m sure many of you have already done this, I still thought it would be a good idea to add to this list. Who knows, maybe you didn’t know about this option.

All you have to do to change your graphics quality is open the Slither.io home screen. Here, you will find a graphics option in the top-right corner, labeled Graphics:. Tap on it to change from high to low.

Reload Servers With The F5 Key

This is something you might not have known; you can use the F5 key to make Slither io not lag. Doing this will reload the website, thus reload whichever server you’re connected to.

Using this method is about as straightforward as it gets. First, open the slither.io home page. Next, tap F5 on the keyboard. It should be located above the numbers 5, 6, and 7.

Use Incognito Mode

A big issue for many browsers or IO games is cookies. More specifically, how they impact the game’s performance. Cookies store data and, in some cases, A LOT of it. Naturally, holding this much information slows your game’s FPS and makes it lag. 

A workaround for this is to use Incognito Mode when playing Slither. If you’re unfamiliar, Incognito Mode is a built-in Google Chrome feature that allows users to browse the web Anonomysley. This comes with the added benefit of removing all stored cookies. As such, it’s one solution to fix your Slitherio lag problem.

To open Incognito Mode, select the three dots in the top-right corner of Google Chrome. If you need more information, refer to the image below p👇. Next, click on the New incognito window button.

Use Game Booster

If that didn’t do the trick, the following method REALLY boosts your game’s performance. 

To begin with, open the Slither.io app. Swipe up on the screen’s bottom or side to reveal the back, home, and overview buttons.

If you’re unsure of what I am referring to, check out the image below:

Next to the three buttons, click the small gaming icon. Doing this will open the Game Booster menu. Here, you want to do two things:

First, enable Priority Mode. This will make the phone allocate more resources during gameplay. Thus, you will get more FPS and less lag.

Second, click the small puzzle piece button with a download symbol (refer to the image below).

Increase FPS

A new window should appear. At the top, tap Game Booster Plus (not the ON/OFF button, but the name). Here, scroll down to Slither.io and select it. Swipe up one Personalized option at the bottom of your screen.

Change the Graphics Quality to 0% and the Maximum FPS to about halfway. This will lower overall Slither.io lag.

Next, tap the Maximum FPS button at the bottom of the screen (not the slider you just changed). Once selected, tap Apply at the bottom.

How Do I Fix Slitherio Lag? For iOS or iPhone

Because of Apple’s nature to restrict the amount of customizability their users have, it’s difficult to change too many options that make Slither io not lag. Unlike Android, which allows users to change many different performance-boosting settings, apple users are stuck with two choices to increase performance:

Disable Battery Saving Mode

If you haven’t already, you must disable Battery Saving Mode. This feature improves the length of your battery life significantly. This comes at the cost of slowing your phone’s performance down.

To begin with, open Settings. From the menu, scroll down to Battery. Here, change Low Power Mode’s green ON slider to OFF.

Play Against Bots

If you haven’t noticed, below the menu’s play online! Button, there is a second option; Play Against A.I.Within this game mode, your internet speed is not an issue because you don’t have to connect to a server. If your game runs smoothly in this mode, it indicates that your problem is not internet-based. Instead, you are dealing with a performance-based issue.

That’s it! We’ve outlined ALL the tips to make Slither io not lag for Chrome, Android, and iPhone. If that didn’t do that trick, I don’t know what will!
