Guild Wars 2

I’ve been lagging out really badly, and no, I’m not blaming the servers. It seems to happen to this extent only with GW2 though. Speedtest.net shows me as over 26 Mbps (bit, not byte) D/L. I’ve got the best cable ISP offered in the Denver area (supposedly).

It’s to the point where I’ll attack 3 or 4 times, then everyone will be just standing there or running on their previous trajectory for 5-15 seconds before letting me get another few shots in. Or I’ll stand there for a bit, then be downed, rally, and be downed again in a matter of a second or two. It’s not just in populated areas, either.

I know that some ISPs throttle your connection when they detect certain things from P2P software, and I read once that occasionally an ISP can confuse a game with P2P software. What can I do, if anything, to optimally configure my TCP/IP settings for GW2?

Intel i5-2500k (3.3 GHz x4)
8GB DDR3 Corsair RAM
NVidia 550 Ti 1GB DDR5

I’m not posting RE: Teq Patch. This has been going on longer than that, and I’m looking only for info about optimizing computer/firewall/router settings.

Someone in-game said something about opening up a port, but I didn’t really understand it. Could someone clarify this, or was that garbage info?

Did the lag start on Wednesday same thing happened to me that night I think its Apples fault everyone is downloading iOS7 overloading the internet. Was on a few hours ago no lag.

No, it’s been somewhat regular for a long time, esp during peak hours. I wonder if my ISP is just somehow getting overloaded or something? IDK how it all works, networking has always been my weak point. What does Apple have to do with it?

Please post a pathping there. Directions inside.

same here, lag since TEQ rising update. sencond update that did it to me. The other one was some months ago, but arenanet fixed it.

No, please don’t turn this into a “the last patch screwed me over!” thread. This is recurring, has nothing to do with Teq, and I am merely looking for a way to optimize my computer’s settings for GW2.

You can try using the TcpAckFrequency=1 reg tweak,it “might” help.But if you have a topnotch connection it won’t make a huge diff.But it can still stabilize your connection.And i do know from when i played Aion it got my ping from around 200 to 50+ ms.

1. Open regedit
2. Navigate here
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\Tcpip\Parameters\Interfaces]
3. You will probably find several “subfolders”. Click through each folder until you find the one with the most entries in the right pane. The right interface will have many entries, e.g. DGCPDefaultGateway, DHCPDomain, DHCPIPAddress, Lease, NameServer, T1, etc.

4. Create a new “DWORD” registry key and name it TcpAckFrequency

5. Double-click on the new registry key and change the value from 0 to 1 .

What we just done is to disable the delayed ACK. ACK (short for ACKNOWLEDGE) is a confirmation that you have received a network package. While you are playing anything online, you are constantly sending and receiving network packets and each of those packets has to be confirmed from your local machine. To prevent a network flood okitten messages (sending out a confirmation for EVERY package) Windows has a smart trick! Windows waits some time (up to 200ms) before it sends out the next ACK, so that it can send out multiple ACK’s in one go.

The solution?
TcpAckFrequency = 1 will disable delayed ACK. Default is 2, so it will wait for 2 packages until sending out ACK.

This doesn’t work on Windows 7 and 8. I have extensively tested this. It does work on Windows XP (not sure about Vista).

If people want to try it out, there’s an easier way than editing the registry. Download Leatrix Latency Fix, available here (yes, it’s safe – I used to use it on XP):

As for the network settings, I changed a few which helps with audio sync issues. The settings below [boxed in RED] are all disabled. Everything else is default; QoS packet scheduler is ON:
