Hi guys, I'll just copy paste the guide I made on the FB page for easier access to other forumers in LYN

[GUIDE - How to get good and stable ping in D3 (Unifi User)]

Hey guys and girls,
Since I have installed Unifi for almost 3 months, I have been getting very bad spikes and pings in Diablo 3. All other games are working fine i.e. Dota2.

I have been cracking my head how to solve this. At last, 5 minutes ago, I discovered something. My 450ms unstable and high pings have become ~200ms constant.

Please be reminded that this might not work on your internet, because the effects might be different. I am just sharing so that maybe you guys can fix it too! Following are the steps:

1. Close your Diablo 3 game.

2. Go to Battle.net Launcher, go to the Battlenet Logo dropdown, choose Settings. Go to Game Settings options. Under Diablo 3, tick the box "Additional command line arguments", and copy and paste the following command:
"OnlineService.Matchmaking.ServerPool=AU1" (Without the ", of course).

3. Close your Battle.net launcher.

4. Go to www.wtfast.com, click on the big blue "Free Download" button. Download the software, and install it. Once you install it, as usual like any other ping reduction softwares, register first.

5. Once you have registered, log in. You can see two options here, one is "Game" and another is "Network". Okey, I will explain for the "Game" settings first. For the "Game" option, click on Custom Games. Then, click "Add". Following are the settings you need to do:

-Name : Put any name as you like, I put Diablo 3.
-Game executable file : Click "Browse", then find your Diablo III.exe. Mine is under C:\Program Files\Diablo III\Diablo III.exe. Yours should be around the same place (Depends on where you install it).
-Click on the option "Run with Launcher". Here, find your Battle.net Launcher.exe. Mine is under C:\Program Files (x86)\Battle.net\Battle.net Launcher.exe. Yours should be around the same place (Depends on where you install it).
-Other options, just ignore it (keep as it is).
-Click OK.

Ok now you are done with the "Game" settings. On to the "Network" settings! Under here, click on the first dropdown and choose "Manually customize network route". For the second dropdown, choose "Singapore (SG7)". This dropdown actually shows you the list of server you can use to connect to your Diablo 3. From my experience, choosing "Singapore (SG7)" is the best ping results.

6. Now you have done with setting your WTFAST software settings. Your Battle.Net launcher should still be closed now. So, click the "Play" button in your WTFAST software (The Play button is located just below the Network settings in your WTFAST software). Wait for it to load, and wait for your Bnet to pop up. If it does not pops up, just open your Bnet launcher manually.

7. Click your awesome blue coloured "Play" button for Diablo 3 in your battle.net launcher, and D3 client should pop up. Here, during the "Connecting to the Battle.Net" server, your D3 client will get disconnected and ask you to log in again where you have to type in your password. Just type your password in, and click log in. Your character select screen as usual should be there.

8. Then, check your WTFAST software if it shows the notification "You are now connected & ready to game!". Then, after sometime, the WTFAST software will show you some network statistics about your gaming session with graphs.

9. If all goes well, and hopefully if it works for you, your ping should be better than before. ENJOY YOUR NEW STABLE AND LOW PING EXPERIENCE!!!
