What is that one thing that no gamer wants while playing Dota 2 online? It’s LAG! Having high ping and latency can cause massive lag, delay and packet loss during the game, making virtually impossible to last hit a creep, cast your spells or use your ultimate in crucial team fights.

Since the launch of Dota 2, lag has been a constant issue faced by many Dota 2 players from around the world. And, if you thought Valve would have fixed this issue after the release of Dota 2 Reborn then you would be wrong. Lag is still a major problem for many Dota 2 players.

You can blame your ISP and gaming servers for causing Dota 2 lag but there are various other factors that cause this problem. Faulty and poor performing hardware (router or switch), congested servers, software issues, and low performance systems can all cause lag while playing Dota 2. So how do you overcome this issue? You can use one of our reviewed and tested Best Gaming VPN 2016 and also follow this step by step guide for fixing Dota 2 lag and packet loss.

Step 1: Optimize Network Connection For Better Pings

In order to fix Dota 2 lag and packet loss, you can optimize your network connection. Having a poorly configured network connection can lead to high ping and latency which results in lag and packet loss. However, you can improve your network connection and reduce Dota 2 lag by taking care of certain factors.

  • Firstly, if you are connected via wireless network connection (WiFi), it is recommended that you switch to wired connection.
  • Turn off Windows Update when you start your system. Also, close any other software updates, installations or downloads before playing Dota 2 online. This alone can improve pings by as much as 300% in some cases!
  • Check your network devices such as a router, switch, or a firewall. At times, network devices cannot keep up with the traffic flow of your internet connection because their memory is maxed out, resulting in Dota 2 packet loss and lag.
  • Look for faulty hardware, especially network cables and ports. If any network component is malfunctioning then you could experience data packet loss and high pings as a result.
  • Make sure that no one else is connected to the same network. For instance, if any member of your family downloads or streams a movie while you play Dota 2, then you are bound to experience lag and delay during gameplay.
  • Turn off applications such as torrents, P2P file sharing software, Skype, or any other program that would consume your bandwidth and create lag in Dota 2.

Apart from taking care of these elements, you can experience Dota 2 lag and packet loss from the server side. This lag can be caused from heavy load on Dota 2 servers. Since your data has to travel through congested traffic from your system to the gaming server and back again, you experience lag and packet loss.

Using a VPN With Dota 2

In many countries using a VPN can fix your lag issues by routing traffic through a more optimal route instead of going through throttled ISPs. The Fastest VPN service with servers in varied continents/countries can help you get better pings to the game server. Here are a few we have tested to be working with the current Dota 2 client:

Step 2: Fixing Frame Rates and Performance

Another angle towards bettering your Dota 2 experience is by optimizing your system to deliver the best performance. Frame rate has a big impact on responsiveness within the game so you need to make sure that any hiccups or lack of responsiveness isn’t your hardware’s fault. Your systems performance can be compromised by several factors such as applications taking up unnecessary CPU usage.

By optimizing your system, you can boost your frame rate as well as ping times when playing the game online.  Here are some steps that you can follow to achieve optimum system performance:

  • Perform disk defragmentation at least once a month. This will improve your systems speed and hence allow better game performance (Frame rate, responsiveness).
  • Close all unnecessary applications, services, and processes from Task Manager before playing Dota 2. This will reduce the workload on your main processor and free up CPU usage for Dota 2, hence reducing load time and frame rates.
  • If you are running Windows, then switch your theme to ‘Windows Classic’. Sometimes Windows Aero desktop visuals can cause issues with the game’s performance when running in full screen mode.
  • Integrated graphics: Increase memory allocation of your RAM or graphic card to get optimum performance. Also, if you can afford it, upgrade your RAM and graphic card.

Step 3: Optimize Your System’s Graphic Settings

Once you have fine-tuned your system and network connection, next you need to optimize the graphic settings as well. To optimize your graphic settings, you can follow these steps:

  • Check the minimum graphic requirements of Dota 2 and see whether your system meets those requirements or not. Most of the time these requirements are met but due to inappropriate settings, you might experience lag in Dota 2.
  • Make sure that the drivers are up to date. New graphic driver patches can fix all the bugs and improve your overall graphic performance while eliminating unwanted lag from Dota 2. Here’s the driver pages for both AMD and Nvidia
  • If you don’t have a monster PC that can run the game on maximum specs, then you can lower your system’s screen resolution. Although it might make everything appear a bit bigger on screen, but your game will run faster, especially if your system is struggling to run Dota 2.
  • You can also change your Direct X settings from DX9 to DX8 for better gaming performance. However, this option might not work if you are using a 64-bit operating system. Also, with new games coming in the market, you would have to upgrade your Direct X to higher version inevitably.

Step 4: Dota 2 In-Game Optimization

After you have configured the graphic settings of your system, you can perform in-game optimization as part of Dota 2 lag fix and packet loss. There are various settings within Dota 2 that can help to increase FPS, reduce lag and help achieve better performance.

Don’t make the mistake that many gamers make while playing any game online. That is to run the game on maximum graphic settings. Unless you have a system with beast of a graphic card, substantial RAM, and a powerful process, you should focus your in-game settings more towards performance over quality. Here are some settings that you can perform in Dota 2 for overcoming lag and packet loss:

Launch Options & Console Commands

You can improve your Dota 2 experience right from the beginning by choosing different launch options and entering different console commands. If you have been playing Dota 2 for some time then you might already be using some of these commands. But if you are new to Dota 2 then might want to consider the following console commands:

  • -console
  • -high
  • -novid
  • -useforcedmparms
  • -noforcemspd
  • -noforcemaccel
  • -dx 11
  • -map dota

Video Settings

Dota 2 Reborn offers easy to use controls through which you can lower or increase your game’s video settings. For starters, we recommend that you set the ‘Resolution’ to ‘Use my monitor’s current resolution’. This will match your systems graphic settings with the game.

Next, under ‘Rendering’ you can choose between basic settings and advance settings. You can slide the bar towards ‘Fastest’ if you want to use basic settings. Dota 2 will automatically configure the graphics to deliver faster performance while eliminating lag and delay.

Alternatively, you can use advance settings and select different aspect of the games that you want switched ‘On’ or ‘Off’. For reducing lag and packet loss, you can lower the texture quality and shadow quality. Also, set the ‘Game Screen Render Quality’ to 50% so the less memory is consumed and your game runs smoothly.

Similarly, keep other settings such as Anti-Aliasing, VSync, World Lighting, High Quality Water, Ambient Creatures and Specular off as well if you want higher FPS rate and fast game performance.

Network Settings

Another setting that you can perform in Dota 2 is selecting the quality of your network. This allows you to optimize your Dota 2 with your internet connection. If you internet connection is great and can handle large amounts of data, then you can leave the setting to ‘High’.  However, if your internet connection is slow then setting the Network Quality to ‘Low’ helps you to reduce lag.

  4. Ruan says:

    I experience the same problem. After last weeks update I have started experiencing lag when I play dota matches. Previously I have not had lag. My internet connection is fine and that is not the problem. My ping is 30ms so I should not experience lag. This happens every minute in the dota matches. How can this be fixed? Because this is now an issue for all my steam games. I tried playing Rocket League but it does the same with this game. Is there maybe an issue with my Steam?

  5. Jm Doroja says:

    Hi ive had this problem and i dont know wether this has something to do with my ping or FPS.. My ping is usually around 85+ that’s the lowest and my FPS is 30-31 max. But even though i get the lowset ping and highest FPS my Dota2 keeps on lagging. Well mostly everytime i interact or go in team fights or whatever my game suddenly lags as hell and i dont know why. Well im from the Philippines so you would expect shitty internet, and my PC is not NVidia….. so U know what can i do? because the past month my gaming was ok. The FPS was fine,then suddenly it freakin drops as low as 11 WTH! so please help me.

  6. Unknown says:

    i usually play normally, about 100 while my loss is always >1%, though the fps only had a minor drop…. i tried to check my internet provider’s connection but everything was fine, no problem at all…. i almost give up on dota bcz this problem keeps making me lose, i mean, who can play with a 3 sec delay in every action? can someone give me some help?

  7. Josh says:

    Not useful in fixing the dota2 FPS drops, which is what people are searching for.

    • /z! says:

      Thanks for your comment Josh. These steps are just to ensure that you rectify the problem from your end. As for the FPS drop goes, this problem is from Valve/Dota2 end. Many gamers (including me) have been experiencing sudden drop in FPS after the 6.86 patch update. However, the new update (released on March 25, 2016) has somewhat rectify this problem, but it hasn’t been solved completely. Looking forward to more updates from Valve.
