One of the greatest franchises of all times is Diablo, and while Diablo 3 is one of the best MMO RPG games out there, it has plenty of problems, from latency issues to poor gpu performance, lets list all these issues and fix them one by one.

 

Diablo III Lag Latency & Ping Problems

 

Diablo III High Latency Issues


There are many things that can cause high latency, from local hardware problems to cluttered networks.
There seems to be a regular problem with Diablo III players getting high latency because of their DNS.

So lets break down how to fix this for MAC and for Microsoft Windows.


Remember to always use a wired connection, they are much faster than any wifi router you can get and much more stable.
IP Release, Renew and DNS Flush on Mac.

In order to fix DNS problems that may be the cause for your Diablo III high latency on MAC you will need to follow these steps:
 

  1. Open the Network Status menu: Apple menu > System Preferences >Network.
     
  2. Select the active connection from the Network Status menu and clickAdvanced.
     
  3. Click Renew DHCP Lease. This process may take a few minutes.
     
  4. Close the Network window.
     
  5. To flush the DNS cache, open the Terminal. (Go > Utilities > Terminal).

 

For OS X 10.10.4 Yosemite and later, type in the following:

sudo killall -HUP mDNSResponder

For OS X 10.10 Yosemite–OS X 10.10.3 Yosemite, type in the following:

sudo discoveryutil mdnsflushcache

For OS X 10.9 Mavericks and OS X 10.8 Mountain Lion, type in the following:

sudo killall -HUP mDNSResponder

Reattempt the connection.

 

Diablo III Rubber banding


Rubber banding is the term used for your character jumping back to where it was a couple of seconds ago, it is an extremely annoying kind of lag specially if you know you did the right move but rubber banding got you killed.
There are many players suffering from it in Diablo III and it seems to be a problem with NAT Acceleration routers.

Some of routers come with the NAT Acceleration feature as a default (or maybe you enabled it), either way this seems to cause problems with Diablo III and cause constant Rubber banding.
It is recommended that you check your routers info to see if it has NAT Acceleration enabled and if so disabling it should fix Rubber banding in Diablo III.

 

Diablo III Stutter and Poor Performance


There are multiple reasons you could be facing stutter in game.

First thing first, make sure your gpu drivers are up to date as this could greatly improve your gpu performance.
If you update your drivers and still face stutter, then there are a couple of things you can do.

The first one is to get an external hard drive, that is faster than your pc’s hard drive and transfer Diablo III to it and launch it from there.
The reason this might work is that Diablo III has to load plenty of resources and slower (older) hard drives might have a huge amount of free space, but they might just be too slow to keep up with Diablo III’s constant information requests.
Only do this if you have an old hard drive or you will spend money on a new one and see little to no difference.

Audio can also be causing your stuttering, and if this is the case then all you need to do is go into Diablo III’s settings and changing to 16 sound and 2 audio channel (which is the least resource consuming option).

And finally if all else fails (or you just want to get it over with) you can go and change some values on one of Diablo III’s files that is sure to fix stuttering.

 

Head to this location:
C:\Documents and Settings\username\Documents\Diablo III

- Open up D3Prefs.txt in a text editor and modify the following values:
- DisableTrilinearFiltering “1” (set to 1)
- HardwareClass “1” (set to 1)
- ChannelsToUse “16” (set to 16)

After you change this setting launch Diablo III and go into you video setting.

From the video setting you will want to:
Disable V Sync

And disable any unnecessary frills, like shadows and reducing spell effects quality if necessary
.

 

Diablo III Stutter On Consoles


There are also problems with stutter from Xbox One and PS4 users, unfortunately there is little to nothing these platforms allow players to do.
If you deal with stutter in any of these two the only thing you can actually do is to uninstall the game, clear some of your hard drives space and re install Diablo III.
If re-installing doesn’t fix the issue there is a high chance that your internet is the problems and not your hardware.

The best way you can fix this is by getting an Ethernet cable connected directly into your PS4 or your Xbox One (or your PC as well…), if this also fails you may want to improve your internet bandwidth speed to at least 2mbps.

If none of this fixes your stutter in Diablo III then most likely it is a problem that can’t be fixed from your side, and unfortunately all you can do is wait till Blizzard fixes it or download Latency Optimizer
