Warzone 2.0: How To Fix Stuttering & Freezing

Last Updated on November 22, 2022

Stuttering in Warzone 2.0: Are you facing constant stuttering and freezing in WZ2? – Worry no more; my guide today will help you solve the problem.

Users on Reddit and Steam Forums are reporting numerous crashes and performance issues. AAA games are no strangers to problems, but it’s hard to understand why games like COD have issues like these on launch days. They have closed beta and open beta periods to test these things. The multiplayer was broken at release and took weeks to get fixed, Warzone wouldn’t take that long as devs work on it on priority.

The good thing is that Infinity Ward is an excellent developer studio, and these problems should be ironed out in a few days. Until then, you can use the tweaks mentioned in this article.

Update: The game is now sitting at a mostly negative rating due to the performance issues and troubles users are facing. I hope the developers take notice and fix this soon.


Fix Stuttering and Freezing in Warzone 2.0

Edit Config Files

The exact same stutters were happening in MW 2019. The game runs fine until you start noticing frequent micro stutters. The fix is the same even for MW2.

  • Go to Documents > Call of Duty > players > Right-click on “options.3.3cod22.cst”, and select open with Notepad.
  • Scroll to the end and locate “RendererWorkerCount.”
  • This setting dictates how many threads the game is allowed to use. It is set to 4 as default, and you will have to change it depending on your CPU.

How To Decide What Number to Enter?

First, find out which processor you are using, launch task manager > Go to performance > Click the CPU Tab, and your CPU name will display on the top right.

After this, Google the processor’s name and find out the thread count that processor has. I am using Ryzen 5 5600X, which has six cores and 12 threads. So, I will put 6 as the “RendererWorkerCount” value. Just input 1/2 of your thread count after finding out the number of threads.

Note: If you still can’t figure out what value to put, there’s a comment section at the end of this article; input your CPU details, and I will help you with this.

This has a considerable improvement and completely fixes micro stutters in MW2. If you are still facing problems, continue reading.


Community Fix

Client Evans on Twitter Tweeted: If you’re experiencing stuttering on PC, change “spot cache” in graphics settings to high or ultra. It’s the shader cache from the last game but with different wording and no longer just a toggle. Assume many just threw it on low. Solved our entire squad experiencing it.

This is working for many.


Verify Game Files on Battle.net and Steam

A broken game installation can make the game act up all the time, so make sure to do this once if you are having problems.

For Battle.net Users

Warzone 2.0 is a game on Battle.net Launcher. To verify the game, follow the steps given below:

  1. Click on the MWII | WZ 2.0 Icon
  2. Locate the Gear Button located right next to “Play.”
  3. Now, click “Scan and Repair” and then click “Begin Scan.”
  4. The launcher will now start looking for any broken or corrupted files.

For Steam Users:

  1. Open Steam and click on the Library tab.
  2. Right-click on MW2 and select Properties.
  3. Click on the Local Files tab > click on the Verify Integrity of Game Files… button.
  4. Steam will start verifying the game files and will fix any corrupted ones it finds.

Use Custom Control Panel Settings

For Nvidia Users:

  • Open up Nvidia’s Control Panel. Right-click on desktop > click Nvidia control panel
  • Click Manage 3D Settings > Program Settings
  • Find “Warzone 2” you can manually add the game if it’s not on the list
  • Now, make the following changes:

Monitor Tech: G-Sync (If available)
Maximum Pre-rendered frames: 2
Threaded optimization: On
Power Management: Prefer Maximum Performance
Texture Filtering – Quality:  Performance
Low Lateny Mode: Ultra (High or Ultra makes sense only for PvP Games)*

Nvidia Low Latency Mode is a feature found in Nvidia’s Control Panel. It is designed to help reduce input latency on Nvidia graphics card systems. Low Latency Mode can be used in games or any other application where you need to reduce the amount of time it takes for your inputs to be registered.

For AMD Users

  • Anti-Aliasing Mode: Use Application settings
  • Anti-aliasing Method: Multisampling
  • Morphological Filtering: Off
  • Anisotropic Filtering Mode: Use application settings
  • Texture Filtering Quality: Performance
  • Surface Format Optimization: On
  • Wait for V-sync: Off
  • OpenGL Triple Buffering: Off
  • Shader Cache: AMD optimized
  • Tesselation Mode: Override application settings
  • Maximum Tesselation Level: Off
  • GPU Workload: Graphics
  • Chill: Off
  • Frame Rate Target Control: Disabled

Disable On-Demand Texture Streaming

On-Demand Texture Streaming is a technique employed by some game engines whereby textures are not fully loaded into memory at the start of a level or scene but are streamed on-demand as the player moves around.

So why does this setting cause stuttering in MW2? – The answer is the game constantly downloads textures, and if the user is using an HDD instead of SSD, Then he will face issues such as stuttering and freezing.


Use Launch Options to enforce DirectX Version

Launch Option to use: -d3d11, -dx11 and -dx12

The above launch option will force the game to run in a particular DirectX version. You can switch between all three and figure out what works best for you.

For Steam

  • Launch Steam > Go to Library
  • Locate Warzone 2 and right-click on it > Select Properties
  • Fill in the launch command as shown in the image below:

For Battle.net

  • Launch Battle.net Launcher
  • Go to the MW2 Warzone Tab and then click the gear button to open the settings window:
  • A new window will open up, click the “Additional command line arguments” checkbox and enter your command.
  • Press “Done.”

I noticed a considerable difference in performance on PCs using older GPUs. Whereas using these commands had little to no difference for newer RTX GPUs.


Move the game to SSD or faster HDD

A Reddit user reported constant stuttering in Warzone 2; someone asked him for his specs, and it turns out the guy had an SSD for C Drive, but the game was installed on the 5400 RPM drive. The user moved his game to the SSD, and the issue was fixed.

As technology continues to evolve, so does the need for better storage. Although hard drives have been around for a while, they are quickly being replaced by solid-state drives due to their increased speed and decreased energy consumption. SSDs are more expensive than hard disks but offer many more benefits. On top of the increased speed, they also consume less power. This is a critical reason SSDs are used in many new devices, from smartphones to computers.

Note: Warzone 2.0 and Modern Warfare II (Including Campaign) are supposedly over 200GB in size. So ensure that you have enough storage before moving the game files manually.


Close any memory-hogging applications

Open up the task manager and check your memory and disk usage. Close all applications (non-windows) that are eating your memory and using a disk drive. If you are still stuttering with everything looking fine, you should probably wait for the hotfix update, which should be pushed out shortly.

Several memory-hungry apps can cause high RAM usage in Windows. One of the most notorious offenders is Chrome. Even when minimized, Chrome can take up a lot of system resources. Firefox and Opera also tend to use more RAM than Edge. If you’re experiencing regular crashes or slowdowns, it might be time to check your app’s resource usage and see if any of your favorites are guilty parties.


Turn off Conflicting Applications

This is a Reddit recommendation; users have reported that software such as iCUE, Razer Cortex, Razer Synapse, and Armory Crate is leading to problems in Warzone 2.0.

These applications are unimportant to me, so I have uninstalled them. I’ve also heard that users running iCUE were handed out bans for no reason. However, you can never be sure about cheaters; they are known for making things up.


Use Process Lasso to limit CPU usage.

Process Lasso is software that helps you limit the CPU usage of a particular app. Download the software and use it accordingly. I was able to drop my CPU usage by almost 20% after using the software. Also, try switching between hyperthreading on/off; this also has a considerable improvement.


Use My Performance Guide

I have already written a comprehensive guide on Best Settings for Warzone 2 and Fixing Lag in Warzone 2.0. Check out both guides and tweaks, this will help you in fixing your problems in no time.


WZ 2 is out now; users cannot hold the excitement, and the massive flurry of players has taken the servers by storm.

MW2’s version of Warzone comes out today, and as usual, the game has tons of issues that lead to crashes and performance issues. This reminds me of when Warzone 1.0 was released in 2019, which ended up overshadowing the development of Modern Warfare, which was abandoned soon after. The same thing happened with Cold War. I hope this doesn’t happen with MW2.

I will be spending my weekend playing multiplayer and writing about it. I already have completed the mind-bending Campaign, you should also check it out.

What are your thoughts on the new warzone?
