Fix Your Lag or Just Improve Latency!, From nexon forum

[Steamb]

This is not a joke. I have been suffering from major lag for a long time, and I have FOUND the problem.

The issue is something known as the "Nagle Algorithm". Anyways I'll keep it simple, this algorithm was created years ago as a way of allowing a steady stream of data to use low bandwidth. It was designed for older dial up modems to prevent online games and other things sending large numbers of small packets from filling up your entire bandwidth sending "ACK Packets". What this does is automatically delay your computer from responding to a single packet by 200ms which allows your computer to respond to multiple packets at once using less bandwidth. What this essentially does, is add up to 200ms to your lag. If you want to know more, do some googling; I don't want to bore you.

Anyways, if you are on a modern broadband connection, you can DRASTICALLY improve your Mabinogi lag by disabling this algorithm. I am unsure of how to do this in Windows Vista, but in Windows XP it is a simple registry edit.

1. Run Regedit
2. Browse to HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
3. It gets tricky here, there be a bunch of Folders with letters and numbers under this Key, you need to find the one that is your network adapter. Browse them one at a time and look for the ones with similar settings to your network, such as if you have an IP address or a Gateway manually set. If you are unsure, you could always just try adding the line to all of them.
4. Add a DWORD named TcpAckFrequency This is Case Sensitive. If it is already there, skip to step 5.
5. Set the Value of the DWORD to 1
6. Reboot your PC

After this, the Nagle Algorithm will be disabled.

If you wish to test your lag, the best way to do it is by casting the Healing spell. Try casting all 5 charges of your healing spell before this fix, then after. I guarantee you'll cast them twice as fast after this fix if you have had lag issues or are living on the east coast.

I was ready to quit this game due to lag issues until I found this. Now all of my problems have completely gone away. If this improves your game performance, please share!

also it doesnt fix server side lag...
stuipd weekends...

This was probably the best upgrade/mod/fix whatever you want to call it I've ever done. Literally I was able to loose arrows almost twice as fast as pre-change. I did notice that when I do get lag hiccups they tend to last alil longer on non-laggy days. Also, like Phill said, if the server is lagging....

try to train my skills during lag
(such as steal.)

[Zephyrus]

yea, this improved my gameplay a lot, thanks steambot

[Charming]

thankies, helped a bunch

[Reina]

ahh this trick is wonderful, i loved it. I didn't have lag at all but it still

that thought of this :D

[Kari]

if anyone knows how to do this in vista, let me know

[Henrietta]

I never personally used Vista, so I wouldn't know. I'll check out google and see if I can come up with something though.

EDIT -


This is what I came up with....

Disclaimer - I've never used Vista, I've never seen this website before, I give no guarantee that this wont blow up your computer and open a gateway to hell. Good luck and god speed
