Fix Call of Duty (COD) Warzone Lag, Stuttering, Fps drops and Crashing

Call of Duty Warzone is a free-to-play Battle Royale game that got released on March 10, 2020. This is the second COD BR title, the first one being Call of Duty Blackout. But Blackout is not free-to-play.

Warzone is a standalone title. So if you were thinking that you need to have Call of Duty Modern Warfare 2019 in order to play COD Warzone, then I guess it is good news for you.

In Battle Royale, it is pretty obvious. It works like every other BR game. You have to survive to be the last squad standing while escaping the deadly gas in the swiftly closing circle with up to 150 players. The map of Warzone is the city of Verdansk that has multiple named zones and close to 300 points of interest. Now it is on you to drop on multiple locations and find out the spot that offers the best loot in Verdansk.

Now that the basic summary about the game is out of the way, let’s talk about how the game performs. If you were around during the launch of Call of Duty Modern Warfare 2019, then you should probably know that how big of a nightmare it was. People were complaining about lag, low frame rates, sudden fps drops, random crashes, freezes constantly. It was a total mess.

COD MW does not have those problems anymore but Warzone is a different title. While players who are using powerful gaming rigs are not facing as many issues, low-medium end users are experiencing some good amount of problems. That is why we decided to come up with a basic lag fix guide that will show you some simple tweaks that you can try in order to fix the performance issues that you are having. Here is how to fix lag, fps drops, crashes and stuttering in Call of Duty Warzone.

How to Fix COD Warzone Lag, Stuttering, Fps drops and Crashing

Compare your Hardware Specifications with the System Requirements of the game

Believe it or not, but the System requirements of Call of Duty Warzone and Call of Duty Modern Warfare are the same. Here are the System Requirements of COD Warzone:


  • Experience : 1080p 30 FPS
  • GPU : NVIDIA GeForce GTX 670 / GeForce GTX 1650
  • CPU : i3-4340 or AMD FX-6300
  • RAM : 8 GB
  • HDD : 175 GB free space
  • OS : Win 7 SP1 64-bit


  • Experience : 1920×1080 60 FPS
  • GPU : GeForce GTX 970 / GTX 1660
  • CPU : Intel Core i5-2500K or AMD Ryzen R5 1600X
  • RAM : 12 GB
  • HDD : 175 GB free space
  • OS : Windows 10 64-bit

Recommended (W/ Ray Tracing)

  • Experience : 1080p 60 FPS with Ray Tracing
  • GPU : NVIDIA GeForce RTX 2060
  • CPU : Intel Core i5-2500K or AMD Ryzen R5 1600X
  • RAM : 12 GB
  • HDD : 175 GB free space

  • CPU : i7-8700K or AMD Ryzen 1800X
  • RAM : 16 GB
  • HDD : 175 GB free space
  • OS : Windows 10 64-bit


  • Experience : 4K 60 FPS with Ray Tracing
  • GPU : NVIDIA GeForce RTX 2080 SUPER
  • CPU : Intel i7-9700K or AMD Ryzen 2700X
  • RAM : 16 GB
  • HDD : 175 GB free space
  • OS : Windows 10 64-bit

If you have problems running Call of Duty Modern Warfare, then you will have problems running Warzone as well. You need a GTX 1650 to play the game on 1080p at 30 fps. But playing a BR game at 30 fps is not a good idea if you ask me.

Though Warzone is a free-to-play BR title, but it is way heavier than other free-to-play BR games like Apex Legends or Fortnite. Neither was COD Blackout less demanding, nor is Warzone. So check thoroughly.

Update your Graphics Card drivers

Both Nvidia and AMD have released multiple drivers optimized for Call of Duty Modern Warfare till date. So if you have not updated your graphics drivers yet, then this is the perfect time to do so. You can download them from the links given below:

  1. Nvidia Drivers
  2. AMD Drivers

Close Discord or tweak some settings

This is something I am writing from my personal experience. Discord initially gave me a really tough time when COD MW came out. Every time I used to start Discord, COD used to start lagging horribly. That is why we decided to use the voice feature for communication until the game was more optimized. But if you don’t want to use for communication, then you have to make few tweaks in order to stop Discord from reducing the performance of your system.

  1. Launch Discord
  2. Go to User Settings
  3. Click on Voice & Video from the left sidebar
  4. Scroll down to Advanced section
  5. Disable “OpenH264 Video Codec provided by Cisco System, Inc.”
  6. Disable “Enable Quality of Service High Packet Priority”
  7. Click on Overlay from the sidebar
  8. Disable in-game overlay
  9. Click on Appearance from the left sidebar
  10. Scroll down all the way to the Advanced section
  11. Disable Hardware Acceleration
  12. Restart Discord

Scan and repair the game launcher users have the feature to scan and repair a game available on the launcher. Same goes with COD Warzone. This feature will verify the in-game files of the game and download the missing ones. Here is how to do it:

  • Launch
  • Select Call of Duty Warzone from the left sidebar
  • Click on Options
  • Select Scan and Repair
  • Wait for the process to be done
  • Restart the launcher

Buggy Windows 10 updates

Microsoft released an update for Windows 10 a few days ago called KB4535996. The KB4535996 cumulative update for Windows 10 heavily buggy and is causing a lot of problems for Windows users. Here is how the update looks like.

If you are not sure whether you have already installed this update or not. Just click on “View Update History” and you will get to see all the latest updates that got installed on your system. If you see an update called KB4535996. You have to uninstall it.

On the Update History window, you will notice the option Uninstall updates on top. Click on it and from the list of updates installed select the one you want to uninstall. Right click on it and click on Uninstall.

Let me make one thing clear, none of these methods are advanced and are pretty basic. There is no guarantee that these steps will fix your problem 100%. If the problem you are facing is a serious one, then the best option would be contacting the support. You can also check out the reddit page of COD Warzone. You will find a lot of people discussing their problems there.

If you think this guide had helped you, then let us know in the comment section below. Also, If you are facing problems that are not mentioned on this article then also you can comment below. We will try to come out with a fix. Good luck!

That’s all folks!

  1. There is another cumulative windows update KB4540673. Does this address the previous updates issues or do we still need to uninstall.

    Thanks for this

    1. Windows update KB4540673 is the latest one if I am not wrong. As far as I know it is safe to download and install.

  2. My graphics are stuttering like shit.

    I’ve done all the steps but still experiencing it.

    My graphics card is a GTX-1060 6b – by Gigabyte

    I don’t know what else to do. Should I try removing my graphics card and putting it back in the motherboard?

      1. I’m using Intel i7 6700k

        Tried overclocking it, and reverting it back to auto. Still no change.

        Also tried removing graphics card and putting it back in, didn’t do anything.

        Tried removing the driver and installing the Nvidia driver back from 2017 (downloaded from Gigabyte website) – still same.

        Could it just be that the graphics card went to shit out of nowhere? I mean what else could I really do at this point? I’ve contacted Gigabyte support so waiting on them.

        However, i think i want to just go get a 2080ti instead.

        1. Same, actually. Also a gigabyte, also a 1060. I’m not sure why there are these huge fps drops in this game. But it is very frustrating.

  3. Hey @ll

    I deactivated the AMD Turbocore technology in the BIOS and fixed the CPU at 3.8 GHz. (AMD FX6300 max. TurboCore 4.4Ghz)
    Since then I have no more lags and I did not have to set anything on the graphics card (ATI Radeon R9 270x 4GB)

    Maybe it will help someone who also has an AMD FX processor. Be careful when fixing the processor, always pay attention to the temperature. Just because the turbocore can operate at 4.4 GHz does not mean that the processor can hold out 24/7.
    Better stay a few hundred MHz below before grilling your processors or putting an unnecessary load on them.

    Maybe it works with your Intel CPU, but I can’t say anything about that.

  4. A friend of me is experiencing lag spikes in warzone. We teste already anything, uninstallin reinstalling game, graphic and sound drivers, putting the whole game at minimum graphics, setting de nvidia panel control settings to max performance, teste de internet connection and called the provider company so nothing had to do with the connection. Heh as a 2060 gtx super with 8gb and a i7 7700 the game was working perfectly at high perfomenca and with no lag spikes or anything. The problem came at tuesday when modern warfare had the server issue problems where everyone was set to a Queue with a pop up message that sas server maintance you will set in a Queue. queue time xxx. after the server came back he experienced the lag spikes. Any idea what could it be???

  5. @Rechy Same issue with me I had 100-140 frames and now i’m stuck with 50-60 around that same time it happened to me as well. I’ve tried everything to fix my lags but I have a 2060 Super and a i7 9700k no temp issues seems like everything is running good. also my PUBG runs at around 150-200 Frames so I don’t see how it would be my computers issue.

  6. i got the same problem… my cod stuck in 50-60 fps … before was 120. Anyone know the solution ? I’ve already reinstalled the windows and cod but still same shit

  7. I think, we all have problems, because we installed shaders not right. So, start reinstalling shaders in graphics menu and than don’t start any mode until shaders was full downloaded.

  8. The problem was the ram, after that “server maintance we set you in a Queue” bug day seems like modern warfare uses more RAM, my friend had 8gb ram he bought 8gb more so now he has 16gb ram and it works fine again.

    1. therre is something else i am on i5 6600k on $,$ghz abnd 16 gb ram and gtx 1070 but same issue which working file on 22 till 2pm IST post that i has a reastrt and this issue started on thing which i have installed in cumulitive update lets remoing this solve the problem or not

    1. I have ryzen 7 rtx2060 Tuf laptop, use to get close to 150 fps on very low setting of 1080 rendering. Now I get around 40 -55fps not sure what changed!
      Tried all the setting mentioned!

  9. Tried everything on the comments, FPS is still all over the place.
    GPU : NVIDIA GeForce RTX 2080 SUPER
    CPU : Intel i7-10700KFc @380GHz
