When I installed League of legends on Windows 7, the ping was OK, but there were these little spikes of lag. Occasionally I would even see "Connection Interrupted" pop up while playing, and there would be a momentary freeze in the gameplay while the game synced with the server. I discovered that this latency/lag was due, at least in part, to certain TCP/IP setting in Windows 7. Below are detailed the steps I took that helped me reduce these latency/lag issues in CoD4 on Windows 7. Note that Step 1 may be all that most people need, but the other steps should help to decrease latency as well.
Step 1
Open a command prompt with admin rights. To do so, go to the following location:
Start Menu -> All Programs -> Accessories
And then right-click on Command Prompt and select "Run as Administrator". If you have disabled the UAC, then you can just open it normally.
Either type, or copy and paste, the following into the command prompt, and then press 'Enter' on your keyboard:
netsh int tcp set global congestionprovider=ctcp
This turns on Compound TCP, which increases the TCP window much quicker than the traditional TCP algorithms allow for. This means that when a sudden burst of larger packets comes in, or goes out, Windows adjusts its settings faster than normal to compensate for it, allow for faster data transfer on broadband connections and lower latency while gaming.
Step 2
Click the 'Start' button, type regedit in the search field, and press 'Enter' on your keyboard. If you don't know how to edit the registry, then you may want to take a look at this article.
Navigate to the following registry key:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces
When you click to expand 'Interfaces', you will see one or more subkeys with long names that looks like the following screenshot:
You will need to know what IP address your computer has on your local network (not on the Internet), and then find the subkey under 'Interfaces' that has the correct IP address. If you don't know how to find out the IP address on your local network, then check out this tutorial. In most cases only one of the subkeys will have all of the information, so it should be easy to find even if you get confused. Look at the following screenshot to see what all of the information looks like:
Once you find it, you need to add two registry values to it. They are both 32-bit DWORD values. They are as follows:
- TcpAckFrequency
- TCPNoDelay
After adding both of those, double-click on each one, and give them both a hexadecimal value of 1, just like in the following screenshot:
After doing that, they should look like they do in the following screenshot:
Step 3
Click on 'Start', click on "Control Panel", click on 'Programs' in the lower-left, and then click on "Turn Windows features on or off" under the "Programs and Features" section. You will want to expand "Microsoft Messaging Queue (MSMQ) Server" by clicking the little plus to it's left, and then expand "Microsoft Messaging Queue (MSMQ) Server Core" as well. After doing that, click all of the checkboxes under the "Microsoft Messaging Queue (MSMQ) Server" section, just like in the screenshot below:
Step 4
If you closed regedit earlier, you will need to open it back up for this step.
Navigate to the following key in regedit:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters
All we need to do here is add TCPNoDelay to the 'Parameters' key, with a 32-bit DWORD value of 1. This will work pretty much the same way that it did before. It will look like the following screenshot when done:
you completed those steps properly, then you should be able to play lol, or whatever other online games you enjoy, with much less lag.
Note that I don't actually understand why installing and configuring Microsoft Messaging Queue helps reduce the latency. I just know that it helped on my computer, and has helped on other peoples' computers.
