Lag



Lag is the delay of data transmission between two digital devices. While considered a glitch by many, lag is not exactly the same. Lag may be caused by a glitch or person. It typically has to do with the server space and a player's own computer. The amount of lag depends on several factors, such as server load, internet connection, and computer specifications.

Lag always exists, from undetectable to complete connection loss which is unreliable. Lag is not fixable by Jagex. Lag is a very common cause of death, so one should NOT partake in dangerous activities while suffering from lag, like playing Barrows, player killing, boss hunting or fighting any powerful monsters.



Computer lag


Computer lag is the most common type of lag, often caused by insufficient RAM (Random Access Memory), CPU (Central Processing Unit) power or GPU (Graphics Processing Unit) power. You know you have this type of lag when the game redraws at a very slow rate, causing the animation to be bumpy. Computer lag is more common when a lot of people are standing in an area, forcing the computer to spend more time redrawing.

Windows users may determine what aspect of your hardware is causing the problem (be it CPU, RAM or GPU) by opening the task manager on Windows and switching to the Performance tab. If you are running a single-core CPU, or if your CPU usage is frequently approaching 100%, your CPU may be at fault; if your Physical Memory usage is often above 80%, you should consider upgrading your RAM (the operating system uses this memory sparingly if it is insufficient, and therefore it is rare that more than 90% will be used at a time); if neither of these hardware aspects appear to be problematic, it is likely that your graphics card is at fault.

Windows Vista is often blamed for being the cause of lag on PCs, while in reality, if properly maintained by the user, it is a respectable operating system. In such a case where you might mistake your problem for Vista's inadequacy, it is most likely that the computer's hardware is actually insufficient. If you are unable to upgrade your hardware, or still feel that Vista is weighing you down, it may be beneficial to reformat your computer. All Windows computers (whether Vista or not) experience "Win rot", whereby the computer will gradually feel slower and slower over time (and this is the primary reason for reformatting one's computer), however this theoretically should not affect RuneScape at all and will only make your computer faster on the whole.

Windows 7, Microsoft's follow-up to Vista, is a faster operating system in general and has received much praise as a result. That being said, it uses essentially the same system to render its interface and thus is equivalent to Windows Vista in how it runs RuneScape.

If using a Macintosh (Intel only) above v10.3, try to be sure that the Dashboard isn't running, Activity Monitor is running in the dock and the desktop is relatively clean. This will free up CPU. Also close out unnecessary windows and don't use Spaces or Exposé.

Another common cause of lag is an outdated system of Java. RuneScape is a java-based game, so you should always have the latest version installed on your computer.

Internet lag


Internet lag is another very common type of lag. It is caused by your internet connection, your Internet Service Provider or bandwidth limitations in the connection to the Runescape server in question. Information is sent from RuneScape to your computer in packages; if these packages become "lost" or corrupted on the way, it may take the RuneScape server a while to realise this and then attempt to correct the error. This form of lag is neither your fault nor Jagex's fault and is typically unavoidable.

If an exception is thrown when attempting client-server communication, the "Connection lost. Please wait - attempting to reestablish..." message appears in the top-left corner. Then the client attempts to reconnect to the server, which may fail. This may happen if the connection suddenly ends, such as by unplugging the Ethernet cable.

Otherwise, no network error is detected and the client continues to attempt communication with the server until time-out. Everything on the screen will freeze, while it is still possible to manipulate already-existing data such as rotating the camera, scrolling through the chat box, or right-clicking items or objects. If connection is not achieved by a certain time limit (five to twenty seconds), the game will automatically log out. In extreme cases, if the amount of data allowed between client and server is very limited, data from the server to client is sent first. This includes movement of NPCs and other players, damage, etc. In this case, the player experiencing lag will be unable to move, talk, eat, or provide any input to the server. If the player is in combat at this time, he or she will not be able to retaliate, even if Auto-retaliate is on. The time-out is irrelevant in this instance, and the player will automatically log out in five minutes (more if in combat). It is not uncommon to watch your character slowly getting killed while unable to retaliate, eat food, run, teleport, or log out.

If your character has just died and has lost items (therefore getting a gravestone), the countdown timer to the gravestone collapsing still runs during lag (for example, if the timer is at 3 minutes, and your character cannot move due to lag, after 10 seconds when you recover you may find that the timer has now reached 2:50). The game treats it as if there is no lag and you are just standing still. This also applies when a server update is due. The countdown will continue regardless of your lag.

There is a way to test for lag. Simply type "Lag" into the chatbox. It will appear when you stop lagging (if at all). If it appears immediately, you may be trying to walk past an obstacle that cannot be walked through or around automatically. This is often mistaken for lag.

Server lag


Lag at the server is common. This happens when the server itself cannot handle the simultaneous requests of all its clients and processes. This is the only lag that is caused by Jagex. It cannot be easily reproduced, and attempting to create this type of lag is reportable under Bug abuse.

Game crashes
When the game crashes because of lag, this is displayed:

What to do when lagging
If you are experiencing lag, you should... Lag
 * Turn anti-aliasing to none in the Graphics options screen. Anti-aliasing is one of the most memory-hungry graphics settings.
 * Download the Windows Client from the Downloads and Wallpapers section.
 * Close any memory and/or CPU intensive programs you have running (including web browsers showing animations like Flash).
 * Pause or stop any downloads you have in progress.
 * Be patient and wait.
 * When logged out, reload the page or wait.
 * Try switching to a world with a lower ping value and/or less people.
 * Choose lower detail options to reduce the memory used by the game.
 * Restart your internet connection.
 * If using a Windows operating system, set the priority of the Java application, and the web browser you are using higher via the Task Manager. Don't exaggerate, though, as this can destabilize your system, thus adding more lag to the game. Likewise, if using Mac, never set the button in the Java Preferences pane to "Run in it's own processes" as this will create unnecessary lag, and use Force Quit from the Apple menu. Only quit processes from Activity Monitor if it's a serious crash.
 * Perform virus/spyware/malware scans to rid your computer of viruses that can hinder your computers performance. This is best done when not playing the game since virus scanning uses a significant amount of memory. Likewise, make sure your antivirus doesn't perform too many background tasks while Runescape is running.
 * Restart your computer. Often if a computer is left on for an extended period of time (e.g. over night), it could be significantly slower.
 * If publishing a video on any video editing software (e.g. Windows Movie Maker), you should publish after playing.
 * Try to play on a world that has LootShare disabled by default.
 * Set CPU usage to "Maximum" under the Graphics options.
 * Cool down your computer - A computer that is overheated can often slow down performance of video cards and other internal components.
 * If you are connected to another computer via cable or wireless (transmitter), pull out the cable or wireless transmitter, and let it cool down. Then insert it back.
