Hello all, I've heard a lot of people have had lag issues during Thaddius and I'm having the same problem. First off, if there is already a thread on these forums about this please direct me. I had a look through the last few pages of posts but couldn't find anything.

I play on Tarren Mill, which is a relatively new realm with decent hardware. The guild I am in don't have any lag issues during raids, which we did before migrating from our old realm. I get through phase 1 of thaddius fine, jump across to his platform and then it starts. As soon as he charges his polarity ability I get massive lag and end up disconnecting. It happens every time, and has made me pretty much useless for this fight. I'm having to stand in a corner each time we try him because if I don't I'll kill our raid.

To try and sort this out, I have cleaned out my PC to prevent any overheating, removed all mods, lowered all graphic settings and even installed the game again. None of these things are working.

And it's not like my PC isn't capable of handling this, I have an AMD 64 3gb processor, a 6800gt card, 2gb of ram and plenty of free hard-drive space.

If anyone could give me any tips on how to sort this out, or if you could tell me that it's a widely known issue and I need to wait for Blizzard to fix it, I would appreciate it. My main concern is that I am the only person in my guild who has this problem and feel like a liability during our thaddius wiping.

Are you using an nforce4 motherboard and using the onboard lan?

I had a few problems with WoW when you are burst a lot of information rapidly, check: http://www.blizzard.com/support/wow/?id=aww01679p under the network cards section, it may not be the answer to your problems, but, it doesnt hurt to try.

I'm using an ABIT AB-8 motherboard. It is using onboard LAN.

Smells like a network issue...

Tried disabling/uninstalling antivirus and firewall?
Do u have a decent connection?
Tried disabling other programs that use bandwidth like vt/msn/dc++/bittorrent/whatever?
Windows firewall on?
If your firewall somehow chokes the wow packets, perhaps you should remove and add wow.exe's access again, giving it full permissions.
Can also turn off your router for 10 mins and then on again.

Also sacrificing some goats often help, not to mention feeding "the small people" that live in the dusty spaces between your keyboard keys. (Any liquid containing sugar helps.)

I've followed that link Maniq and edited the network settings like it described.

I'm using McAfee VirusScan and Firewall with this acting as my firewall. My windows firewall is off. I've closed all other applications while trying the fight and I'm still getting the same problem.

The link you provided Maniq suggests turning off my virus protection to see if it's that. I'll stick on my windows firewall and disable McAfee and maybe that might help. Anyone got any other ideas?

I recommend turning off ALL firewall/antivirus software on your next try. Just to make sure if thats where the problem lies.

Unless you happen to surf tentacle-porn at the time and/or are the worlds unluckyest man and get haxxed in the 10 mins you are without protection, you should be fine.

This boss is just stupid. We´ve known for over a month exactly how to kill him, but the server keeps preventing us from doing so. It's very very frustrating, I wonder when Blizzard will at least comment on it. They can at least say if it's impossible to fix.

I can assure you it's not graphics, and it is most definitely connection. I personally can go on my crappy PC running at near minimum specs but with a direct connection to my router and do Thaddius just fine, yet I will d/c every time he polarity shifts when I go on my newer PC (on wireless internet) that can handle pretty much anything graphically yet can't stay online for Thaddius.

Ok, my problem has got a little better. I did everything I have been told here and I've disabled all virus programs and firewalls. I'm not getting crashes anymore when Thaddius does his polarity shift, but I am still getting massive lag spikes that put my raid in danger of wiping.

Any more suggestions would be greatly appreciated.

Scrap that, I just got disconnected again when he does his main ability. I'm totally lost now as to what I can do to fix this. I am totally bewildered by how I am only getting this problem during this one fight.

Well I just spent another 4 hours tonight dying in a corner.

Someone in guild suggested I disable my graphics card to see if this is the problem. Before I do this however, and because there is a reset tonight and I have another day or two to wait before trying this I would love it if you could suggest anything else I can try to fix this issue.

Thanks in advance.

Surely it can't be if its happening repeatedly at the same point continously and nowhere else? Unless my ISP is spying on me when I'm playing WoW, i find it hard to believe that it is a network issue.

Explain to me how frame rate lag would ever cause a server disconnect?

how many UI mods are you using that parse the combat log?

try disabling everything except the most essential stuff. People running both SWstats and Damagemeters at the same time were a prime culprit when it came to thaddius polarity disconnects

frame rate lag can occur when a lot of sending/receiving information from mods like damagemeters and SWstats is going on, and this same circumstance can trigger Blizzard's flood control mechanisms, disconnecting you from the server. the polarity shifts dump a ton of information in the combat logs for your UI mods to sift through

I have tried the fight with all my mods uninstalled completely and it is still happening. I've also tried lowering graphic settings and a complete fresh install of WoW.

That's not the frame rate lag that's causing the disconnect, that's the cause of the frame rate lag causing the disconnect. The two are very different animals, and I still maintain that trying to search for problems with his graphics settings is not going to help anything ;)

Our guild's resident UI Expert (Tivoli) said that most people who get disconnected or lag out is due to one of two things. First he mentioned that the Thaddius encounter floods UI memory usage and there is a cap on how much memory is allocated before you get disconnected. So if you're UI/Mods take up a ton of memory (in a raid I am always less than 20MB) the encounter might put your usage over the edge. The other thing he gave us was a script to turn off events in the combat log. I forget this script off hand and am not in game now. We have only had 1 person disconnect on the fight so far and that is because his computer is beyond shitty along with his connection.

I know you guys are only trying to help, but if you actually read my comments before posting, you will have noticed I have said I already tried a fresh install and have deleted all mods. This means that my UI memory is obviously not the issue, and either is my WDB and WTB folders as these were deleted when I installed again. If you have a copy of that script you mention Bhaltair I would appreciate trying it, but to anyone else who wants to pass on their wisdom, please take a look at all the replies before posting.

Have you tried the suggestion mentioned above? Buy a different network card?

Before you dismiss the idea as impossible, consider that Thaddius might result in a massive spike of network traffic during the polarity shift, and it's possible that your net card/router/hub/ whatever simply can't cope.
This problem sounds very similar to the problem we've had in the past with a couple of folk who consistently disconnect during the Razorgore encounter - and that was definitely connected to network card/traffic problems.

Buying a good net card might just solve the problem - and it sounds like a pretty cheap thing to try. If it doesn't work, you have a decent net card anyway - or you could simply take it back to the store and say you don't want it anymore O.o

Any new suggestions on this? Our server finaly got hardware upgrades but I still experience the same freezes+DC. When the polarize comes My fps stays around 40fps but I can see how the polarizies are applied slowly to players and the pace picks up alittle to the end. When the second polarize comes I usually get DC after I see a couple polarizes being applied.

My comp:

3500+
7800gt
2gb mem
10/10mbit internet connection

I have tried the following:

- Tuned down all gfx settings
- Removed all mods + wtf+ wdb
- Removed my firewall
- Changed to a 3com NIC
- Ran repair.exe

Would you be able to post this script since some people in our guild disconnect when the polarity shift happens. Would like to see if it helps on the encounter.

Saw this posted in the R&D a while back and took note of it.
No idea if it works dude1:

/script ChatFrame2:UnregisterAllEvents();
/script ChatFrame2:Hide();
