Iah and latency issues for na players.

maxnrosy

So thqice has closed their beta and well we have to wait.  well Iah server is on open beta and we can all join , however you may notice some bad latency issues , especially with chars that need to do combos in the air, you just miss your attack due to latency.

well i did stuble on this on the iah dragonica fourms

If you havent already, you can disable Nagle Algorithm from your registry.

Since you'll be messing with your registry, it's up to you whether or not you want to.

Before I tell you how to disable Nagle, let me tell you what it is.

Nagle Algorithm is a system which restricts the number of packets being sent to and from a network. Ping is then determined by the amount of time the packets are sent over a network. Disabling Nagle Algorithm equates to more packets being sent over a network, which equates to lower ping.

Alright now. Even if you didn't understand any of that, here are the steps:

======For Vista Users=======

1. Go to the Start Menu.

2. Type "regedit.exe" or just "regedit" (No quotations).

3. Browse to HKEY_LOCAL_MACHINE SYSTEMCurrentControlSetServicesTcpipParameter sInterfaces

4. Look for a folder that contains your LOCAL IP ADDRESS under the Data column. The folder that it's in should be named similar, but not restricted to {1C3DE298-6536-4E3B-8BE6-457838544F56}. If there are more than 1 folders that contain your local IP, follow steps 5~8 in those folders.

5. Go to [Edit]-[New]-[DWORD (32-bit) Value]

6. Name the new file TcpAckFrequency. This is CaSe SeNsItIvE.

7. Right Click on TcpAckFrequency and select [Modify]

8. Set the Value Data to 1 and check off Hexadecimal.

9. Restart your computer.

=========================

========For XP Users========

1. Go to Start Menu.

2. Click the "Run" button.

3. Type in "regedit.exe" and hit enter. (No quotations)

4. Browse to HKEY_LOCAL_MACHINE SYSTEMCurrentControlSetServicesTcpipParameter sInterfaces

5. Look for a folder that contains your LOCAL IP ADDRESS under the Data column. The folder that it's in should be named similar, but not restricted to {1C3DE298-6536-4E3B-8BE6-457838544F56}. If there are more than 1 folders that contain your local IP, follow steps 6~9 in those folders.

6. Go to [Edit]-[New]-[DWORD (32-bit) Value]

7. Name the new file TcpAckFrequency. This is CaSe SeNsItIvE.

8. Right Click on TcpAckFrequency and select [Modify]

9. Set the Value Data to 1 and check off Hexadecimal.

10. Restart your computer.

=========================

You may or may not notice a difference in performance, but the restriction is gone, and as long as you don't change computers, other online games should run with Nagle disabled.

 

This did help somewhat now i can actually pull my air combos off much better than before and actually not get hit when i avoid a boss attack. Now the latency is kinda high still  its not as fluid as the thq servers, but then those servers are down.

This does seem to apply to other games to boot so i guess players from games like darkfall (hurls) can take advantage of this.

as always use at your own risk.
