Epic Games explains in-depth an issue causing specific players to lag in Fortnite

Published

on

Epic Games has posted a technical blog post detailing a network issue which may be causing lag and packet loss for players using a specific internet service.

The post was written by Ryan Gerleve, Lead Networking Programmer at Epic Games. In the post, Ryan goes into great depths explaining what is causing the issue and how Epic plans to remedy it.

Interestingly, the issue lies within Unreal Engine 4, the engine which powers Fortnite and many other popular games such as Player Unknown’s Battlegrounds. Check it out below…

We recently tracked down, with the help of an internet service provider (ISP) and one of our hosting providers, a networking issue that could be contributing to some of the lag and packet loss that players with certain ISPs are experiencing. This post is to provide some technical details about the problem and how we’re planning to fix it.

The issue relates to how UDP network packets can be delivered to their destination in a different order than they were sent. This is a protocol that all programs using UDP for networking have to deal with, and Fortnite, by way of Unreal Engine 4, does handle it, but not as efficiently as it could.

To help understand the issue, here’s a simplified version of the high-level sequence of events that occur in a single frame in-game.

  1. Try to read a packet from the network, if one is available, go to #2. Otherwise, skip to #4.
  2. If the packet read was sent before a packet we’ve already processed, discard it. Otherwise, process it normally.
  3. Go back to #1.
  4. Advance the game simulation and wait for the next frame.

We can do the test in #2 because the sender writes a sequence number into each packet they send, and the receiver records this number for the last packet it successfully processed. Discarding packets with lower sequence numbers is important for keeping the game simulation consistent, as well as for security reasons – we can’t just process every single packet regardless of when it’s received.

Now, consider a case where the packets the game receives are out-of-order. For example, if the received sequence is 1, 3, 2, 4, following the steps above, we would process packet 1, then 3, discard 2, then process 4.

Discarding packets here is generally OK, because we have mechanisms to retransmit packets if needed – but this retransmission takes time, so in effect it causes increased latency for whatever actions would have been triggered by processing that packet.

However, the game did receive every packet the sender sent, and it technically could have processed packet #2, so dropping it might seem wasteful – and it is!

If the out-of-order packets are all received on the same game frame, we should be able to sort them into the correct order before fully processing them. Consider this revised processing loop:

  1. Read all packets available from the network. If any are available, go to #2. Otherwise, skip to #4.
  2. Sort all packets received by their sequence numbers.
  3. Process all the packets in their now-sorted order.
  4. Advance the game simulation and wait for the next frame.

Now, we can process all the packets received in the example above without discarding any and paying for the re-transmission time of whatever data packet #2 contained!

We hope to have the revised processing method implemented in the v8.10 update but will update you on the timing for the fix closer to the release of that patch.

How to get the Dish Destroyer pickaxe in Fortnite Season 3

Another exclusive pickaxe arrives to Fortnite in Season 3 and it sure looks quite different. Here’s how you can get it.

Dish Destroyer Pickaxe in Fortnite

The Dish Destroyer pickaxe is another free cosmetic you can get in Chapter 3 Season 3 if you haven’t already. Here’s how to get the pickaxe right into your locker.

Fortnite players sure love freebies that the developers give them away each season. From a free Refer-A-Friend skin to a slurpy back bling that you can get upon completing quests, players have faithfully completed every task that Epic has asked them to claim the free reward.

However, over the course of several seasons now, getting these freebies is starting to feel too much work to some players. Epic continues to add away free content, but players are asked to put in the work in order to claim these rewards.

This time around, there’s a new item on the block, The Dish Destroyer Pickaxe, which you can get in Fortnite now by doing a few simple steps. Here’s how you can get it in Season 3.

Get the Dish Destroyer Pickaxe in Fortnite now

Nvidia’s cloud gaming platform GeForce Now was launched earlier this year when players were able to stream Fortnite on any device if they were a member of the service. This also allowed iOS users to stream the game on their phones despite the Apple vs. Epic lawsuit.

In a recent tweet, Nvidia announced that Fortnite players will be able to redeem a free Dish Destroyer Pickaxe if they stream Fortnite on their GeForce Now enabled devices until August 4, 2022. Players who are members of the exclusive service will only be able to redeem this for free in-game.

However, in another announcement, Epic told its player base that the pickaxe is not exclusive to GeForce Now but will also be available in the Item Shop at a later date. This means that those who aren’t able to redeem the free pickaxe using their GeForce Now memberships will have a chance to buy it using V-Bucks in the Item Shop.

The cost of the pickaxe has not been revealed as of yet as players believe that it will be released once the limited window of August 4 for GeForce Now members have expired. As soon as we get any news on its Item Shop release, we’ll be sure to update this article.


GeForce Now players have had the perks of free rewards ever since the service allowed players to experience the thrill of Fortnite anywhere on their devices. Falling in line is XCloud’s gaming service which has become extremely popular amongst Xbox players.

Fortnite players call on Epic Games to fix Loot Chests bug in Season 3

As the latest Fortnite Season 3 update brought players a No Sweat Summer, it left a weird bug in the game where players are getting empty loot chests. Here’s the latest on that.

Loot Chests in Fortnite

Fortnite players have finally given up on the game due to its never-ending glitches and bugs that affect their overall gameplay experience. The latest glitch in the game is teleporting chest loot to a different location, and it’s getting pretty annoying for players.

Player feedback is one of the many things Epic takes very seriously that it aims to fix in every major weekly update or minor hotfixes from time to time. Often there are times when these bugs can get pretty annoying as they affect the overall gameplay experience for the player.

Fortnite players have seen bugs ranging from being stuck under the map or taking fall damage after jumping off a launch pad. From pros to content creators, each one of them took to social media to call on the developers to “fix the game”.

However, a recent update, v21.30, left a bug that has tested the patience of every Fortnite player active this season – potentially the most annoying Fortnite bug of all time. Here’s everything we know about it so far.

Fortnite bug teleports chests loots to other locations

A strange Fortnite bug that is going viral right now on social media is the Loot Chests bug. It all began when Epic added the update v21.30 and introduced players to this year’s summer event, No Sweat Summer.

The update also saw the addition of Prime Shotgun which is considered to be the best shotgun in Chapter 3. While all the additions are fascinating and exciting to the players, the bug the update left in the game is still haunting players who are failing to win a game like they used to.

The bug, as shown in the clip above, teleports the chest loot to a nearby location outside if a player opens a chest box inside a building. This is pretty annoying as it doesn’t let the player farm loot fast as they usually would while landing on a hot drop.

Players have already started uploading their clips of the loot chest bug and are calling out the game to come out and fix this issue. This bug also creates double the work for those players who like to play a fast-paced Battle Royale match.

Joining in the conversation are a few FNCS players who feel that this bug might cost them several games where they would end up losing on a major competitive level. The entire community has joined hands together to ask the developers to fix the game at the earliest.

While Fortnite has not addressed this issue on their social media handles or on the Trello board could also mean that players in higher ping regions might be the only ones experiencing the bug. However, the player base is still keeping their hopes high to get these issues fixed as soon as possible.


As bugs and glitches continue to add to several issues Fortnite is filled with, events like No Sweat Summer keep the community excited for more in-game content and freebies that they can get. The challenges for No Sweat Summer are live in-game now and players can redeem their share of rewards upon completing them.

Fortnite introduces the new Prime Shotgun in update v21.30

Prime Shotgun is the latest game breaking weapon that has been added to Fortnite in v21.30. Here’s all about the new shotgun.

Prime Shotgun in Fortnite

Prime Shotgun is another addition to Fortnite this season in terms of weaponry that has been added to the game. Here is all about the latest shotgun that was introduced in v21.30 and what players think of it.

Fortnite Chapter 3 Season 3 has been a joyride for both OG and new players alike. The new mechanics, the reality bloom spreading everywhere, and the addition of new weapons to the game have kept the community satisfied so far.

However, during the beginning of Chapter 3, the shotgun meta was deemed to be the worst shotguns the game had added to the game. The Striker Pump, Ranger, and Auto Shotguns were weapons that players had deemed incompetent to other shotguns in Fortnite.

Much so, even the newly released Two Shot Shotgun couldn’t impress the players with its faster fire rate and damage. So, Epic decided to throw a new shotgun into the mix to seek player reactions and improve the messed-up shotguns in-game.

Prime Shotgun is the new community favorite shotgun in Fortnite

Prime Shotgun was added in the latest update v21.30 to the unvaulted weapons arsenal in Fortnite. The shotguns were the second one introduced to the player base apart from the Two-Shot shotgun.

It holds 4 bullets in a clip and promises heavy damage on the first shot fired from a fully loaded clip. The 3 shots that follow inflict lower damage than that of the first one.

When a player reloads the shotgun, 3 blue dots appear on the gun with the red dot being the first shot being loaded. This brings back the memories of the infamous “One Shot Meta” from the OG days when the community used to perform using a Pump Shotgun.

Pros like NickEh30 sang high praise of the Prime Shotgun as the weapon contains elements of the OG pump in terms of range, accuracy, and firepower. Other pros like SypherPK & Ninja also commented their thoughts on the gun which were highly positive.
