Fix WOW - Battle Of Azeroth Login, Lag, FPS & Latency Problems (UPDATED)

UPDATED 21.07.2019   10:00


A new chapter of the epic Warcraft saga is Battle of Azeroth that offers new features, game play, story and much more. As the player base of WOW is a bit rising after a 3 years down, so do the probelms with lag, fps, ping, latency and other performance issues. To be clear on that, the issues are mostley caused by ISP (Internet Service Providers) and user side and not by Blizzards game servers.

We all know that game servers do have down times or performance issues from time to time but they are solved in few hours. The issues caused by player side are mostly permanent. Thats why we came up with a all-in-one solution in this article.


WOW Lag - Battel of Azeroth Troubelshooting Tips

New expansions old, but working methods to fix lag, latency, fps, ping and other performance problems.

Here is a list of links for tips & tricks to get a smoother game play:








World of Warcraft Video Options

The options in WoW are very simplified and well described. Here is the list of each options and how it affects the game. We will start off basic graphics options before we move onto the advanced video settings.

Display Mode: Player gets to pick between two displayed modes, that being Windowed and Fullscreen (Windowed)
"The important takeaway is that Windowed Fullscreen now has the slider options from Fullscreen to try to minimize the impact to your play experience." - Blizzard Dev

Window Size: Lets you select the size only when in Windowed Mode

Resolution Scale: 3D quality of the world surrounding the player

Monitor: This options lets you select which monitor want to use.

Anti-aliasing: CMAA is incredibly lightweight and gives excellent results for a post-process solution. I'd recommend keeping that enabled no matter what, then pushing some extra MSAA or SSAA if your GPU can handle it without impacting performance (you can combine anti-aliasing modes in the advanced options). SSAA will give better results than MSAA, but it's also much more demanding.

Avoid FXAA. FXAA tends to overly blur the image while being less effective than and about as costly as CMAA. FXAA is only really useful if you're stuck in DirectX 9 mode (at which point you desperately need to upgrade regardless).

Vertical Sync: Turning off VSYNC will cause for the system to work harder, but that doesn't necessarily mean that the system won't be able to handle it, so if you feel that the game runs better with it off then you are more than welcome to run it that way. That's why there is an option to disable it. Our recommendation is to leave it on, but that's just because we feel it doesn't make much of a difference.

Rest of the Options are pretty much described in-game when you hover over a mouse. Each setting lets you know what in-game will change.

You can check it in our Video Guide here:


Advanced Settings

Triple Buffering: Triple buffering simply buffers one extra frame to the cpu instead of two. This extra frame gives enough time to correct more issues such as frame tearing and Vsync. It also has drawbacks. A extra frame being buffered by the GPU means it must use more on-board GPU memory to store and buffer that frame.

MSAA (Multisampling Anti-Aliasing): The AA options are MSAA,

Multisample Alpha-Test (only applies when MSAA is on), Post-Process AA and Render Scale. The presets apply specific mixes of these, but MSAA and FXAA are never combined with any other options (thus attempting to combine them will always be "Custom").

Post Process AA: Post Processing AA usually does not affect fps at all, but it is nowhere as sharp as the non-Post AA, but if your game looks good with MSAA, you don't have to use it.

Resample Quality: When downscaling (Render Scale over 100%) there's very little appreciable visible difference between the two. Bilinear will run ever so slightly better, but that's about it. You can, of course, find examples where one produces preferable downscaling results over the other, but that's only really noticeable when zoomed in on stills - in-game, where things will be moving, and at a 1:1 viewing ratio you're extremely unlikely to see it.

When up scaling (Render Scale below 100%), however, the two start to become appreciably different. Bicubic is generally considered preferable as it retains some semblance of sharpness, where-as Bilinear is quite literally just blurring the results.

Graphics API: An Application Programming Interface (API) defines the way that applications interact with components of a computer system. In the case of a graphics API, this interface is typically implemented by driver software that is written by graphics hardware vendors.

Physics Interactions: It's the dangly parts of weapons and belts etc.

Graphics Card: Lets you select which one you want to use if you have multiple. Auto options will select the better one automatically




Optimize Network for Speed: It disables packet piggybacking acts to remove any information delay caused by this delay of information. To understand what this means I will use a metaphor. Imagine two people playing catch with a baseball with a guy in middle announcing throw count every 2-3 throws.

The information is obtained, but not in realtime. It's more efficient as it uses less words, but in terms of real time information, inferior. Now imagine instead that announcer is announcing after every single toss. So you get more real time information on throw count, but at the cost of additional words used. Now just substitute baseballs with packets, and words with network bandwidth.

This what optimize network for speed does, it makes wow use SUBSTANTIALLY more bandwidth. This feature is only used in INSTANCES. It has no bearing on behavior outside of battlegrounds/arenas/dungeons. Regular world servers use old network protocols and not this new option.

In order to have more control over bandwidth together with many more optimization options, you can use Latency Optimizer 4 software and disable the in-game options.

Enable IPv6 when available: In short, there are a couple of answers based on what your IPv6 address is, but it's generally better (in terms of game performance) to disable IPv6 for the time being.

IPv6, as you may know, is the next generation of IP. It's significantly different from the current version, IP version 4 (version 5 was skipped). An entire volume could be written about the differences between IPv4 and v6, and if you're interested, I definitely recommend doing some research on it.

There are generally two ways to get an IPv6 address:

Native. This means that your ISP is actually assigning your router an IPv6 address in a similar fashion to how they assign the IPv4 address.

Tunneled. This is a transitional technique by which your router or your computer are automatically configuring a tunnel by which IPv6 traffic passes over your existing IPv4 connection. There are several ways to do this.

For example, Apple AirPort/TimeCapsule routers can run a tunnel so that your machines behind it receive IPv6 addresses almost as if they were on a native network. Another method is where each machine will try to tunnel all by itself, without the help of the router.

Advanced Combat Logging: Lets you track characters movements and stuff during fights


World of Warcraft Latency Fix

Reset your User Interface to make sure some of the add-ons aren't causing problems. Type /reloadui in chat
Restart your router (Unplug from socket, wait a few minutes, plug it back in)
Disable or allow WoW in your anti-virus Firewall.
Make sure you wireless connection is not overloaded by mobile devices. Most of mobile devices have auto-update feature on their applications.
Update your GFX drivers and make sure OS version is not outdated.

We hope this helped. Have fun!
