DPC Latency

The DPC latency is the time it takes for the CPU to process certain tasks.The lower your latency is the quicker is the response of your system. Even when you own a blazing fast computer, some drivers can conflict or be out dated, which causes DPC drops.

Download DPC Latency Checker: http://www.thesycon.de/deu/latency_check.shtml

** Don\'t use it on Windows 8 as the results are not exact **

The graph shows you the latency and should always be in the green area like in the screenshot.

If you see your latency rising up to the yellow or red area you should take care about it.

Cleaning up the device manager is the first to do.

Device Manager

The following step will bring up all the hidden entries in your device manager.

#1

open properties of your computer

#2

click on Advanced system settings and then on Enviroment Variables

#3

Add a new user variable

variable name: devmgr_show_nonpresent_devices

value: 1

Hit ok ok ok

#4

open your device manager

under view select show hidden devices

Now go through the list and delete all the unplugged devices you don\'t need anymore.

By that I mean the grey marked entries.

Do not delete the Generic volume shadow copies as they are related to the windows restore points. Except you know what you are doing like in my case I deactivated all recovery functions.

If you are using a virtual drive like daemon tools unmount if you don\'t use it all the time.

Deactivate the onboard sound if you are using an additional card.

Under "System devices" deactivate the "High Definition Audio Controller" if you don\'t use the sound output of your graphics card.

Deactivate all the network drivers (features) except the one you really use.

Deactivate all the usb controller you don\'t use. This can be a bit tricky and you should only deactivate the controllers one by one and restart. As mentioned above, the tool Everest shows you what is plugged into the controllers.

Plug your mouse in a dedicated and free usb controller to ensure the full bandwidth.

Restart your computer and see if this helped to lower your DPC latency.

If you still see some heavy spikes you could deactivate every driver one by one to identify the troublemaker. Try to deactivate all drivers you don\'t need to run the system. Like CD-ROM, Sound, LAN, USB-Controller...

Use device manager and disable power saving for LAN, WLAN, and USB devices.

Timer Resolution

I just found this little tool called Timer Resolution.

By clicking on the ‘Maximum’ button you reduce the interval, your Windows will react to new tasks.. This should also be visible in the DPC Latency Checker.

I’ve checked the tool for a long time now on many systems and with friends of mine. The performance difference can greatly vary from system to system.

BIOS (only for advanced users)

Disable C-States

Disable Hyperthreading

Enable/Disable the HPET (High Precision Event Timer)

Some people say it performs better with HPET Enabled. Some say different.

So test this for yourself.

If you don\'t find the option for HPET in your BIOS try to use these CMD lines:

Start CMD with admin rights

To enable type: bcdedit /set useplatformclock true

To disable type: bcdedit /deletevalue useplatformclock

If you want to go even deeper into the material you should check out this tutorial.

You will find some nice tools to check your system drivers for any DPC latency issues:

http://www.sysnative.com/forums/windows-7-|-windows-vista-tutorials/5721-how-to-diagnose-and-fix-high-dpc-latency-issues-with-wpa-windows-windows-vista-7-8-a.html

I found out that one of my cpu cores produced some higher dpc latency. By disabling that core in the BIOS I could lower the latency noticeable. As I have still 5 cores left, it doesn\'t make a big fps difference in cs:go.

What ever I do, I can not drop my DPC latency under 30. But my values never go above 100. So at the end you have to live with what you get.

Happy testing :-)

Internet Connection and Network Settings

LAN/WLAN Connection

First of all I can highly recommend you to use a LAN Cable. A Wireless connection is much more susceptible to errors.

However you should always keep your router\'s firmware and of course your network drivers up to date. In many cases changing the WLAN channel in the router settings can help to get a better wireless connection. Therefor you have to google a bit for yourself. Every router is different and i cannot go more into detail.

Follow these steps to check the connection to your router:

#1 Open the "Command Prompt" (CMD)

#2 Enter: ipconfig

As you can see in the screenshot, this will bring up all Adapter-IP assignments.

#3 Find the network adapter that is connected to the router and search the "Default Gateway". You need the router- (gateway-) IP for the next command.

#4 Enter: "ping -t" and add the Default Gateway IP. So like in my case: ping -t 192.168.178.1

As you can see, every second a little package (ping -t) is send to the router (192.168.xxx.x) and back again.

While this is running, you should stop all ongoing network traffic of your Computer.

Keep an eye on the time column. In the screenshot above, you can see an example of a bad Wireless connection. the ping is jumping up and down between 1 and 10 or even more. Changing the routers\' WLAN channel or the position of your router can fix this problem. A good wireless connection should look much more stable though.

Here is a screenshot how it should look like with a wired connection:

the time is less than a millisecond with a 8m long cable.

If you experience a bad wired connection you probably wanne test a different patch cable and reset and/or update/downgrade your network adapter drivers.

If your connection to the router is fine you can go on to the next step.

Internet Connection

Check your Internet connection for ping, latenzy and packet loss. Therefor you can use for example web-tools like http://www.pingtest.net/

Make sure that nobody in your network or any programs in the background are using your Internet connection before running the ping test. If you notice any packet loss or strange peaks during the test, there is nothing you can do but calling your internet provider. They can fix most of the bandwidth related ping problems.

Network Driver Settings

Setting up the network driver for gaming is another topic of its own.

I can highly recommend this little tool called TCP Optimizer.

download here: http://www.speedguide.net/downloads.php

My settigns:

First apply the preset "optimal" and reboot.

Then change "LargeSystemCache" to disabled: 0

Enable "TcpAckFrequency" and "TCPNoDelay" (This may slow down your browsing experience but enhances your gaming feeling)

Apply and reboot again.

You can find the explanation for every setting on this page:

http://www.speedguide.net/articles/windows-7-vista-2008-tweaks-2574

The Right MTU

This setting has no impact on CS:GO, because the game is using the UPD and not TCP protocol.

But setting up the right MTU improves the general bandwidth throughput for all TCP applications like browsing downloading and some other games that use TCP.

Follow the steps on the webpage to find your MTU:

http://www.dslreports.com/faq/695

Every setting you change is recoverable. So experiment for youself.

The preset "optimal" should be a good starting point.

LAN Adapter Settings

Go to your Network Connections

Select the properties of your Adapter

Click on Properties

Untick all the items you don\'t use. For example I only use TCP/IPv4 in my network and nothing else.

Set a static IP for your LAN Adapter
