How To Fix Overwatch 2 Keeps Crashing [Tested Solutions]

We explain how to solve the issue by turning off Windows Defender Firewall, disabling fullscreen optimization, repairing game files, and more!

If Overwatch 2 keeps crashing for you either at startup or mid game, you’re not alone. Plenty of other players face the same issue, which isn’t due to a single reason. Overwatch 2 can keep crashing for several reasons, such as corrupt game files, incorrect video settings, and firewall restrictions.

However, a couple of methods, such as turning off Windows Defender, disabling third-party apps, and many more fixes, can help you solve the issue in minutes. Let’s explore them one by one.

Key Takeaways

Here are a few fixes you can take a look at to keep Overwatch 2 from crashing:

  1. Allow OW2 Through Windows Defender Firewall.
  2. Disabling fullscreen optimization.
  3. Disabling third-party Peripheral Applications.
  4. Finding and removing Razer Chroma Sdk.Dll file.
  5. Keeping Overwatch 2 graphics preference set to high.
  6. Turning off Game Mode.
  7. Use The Battle.Net Special Command.
  8. Set Overwatch 2 Priority To Realtime.

For Mid Game crashing try these solutions:

  1. Create a new Windows user account.
  2. Increase game priority for better resource allocation.
  3. Disable overclocking for stability.
  4. Disable Radeon Boost for AMD Radeon 6000 series cards.

Allow Overwatch 2 Through The Firewall

The Windows Defender Firewall is excellent for keeping your PC safe from threats. However, it can sometimes interfere with your applications and cause them to crash.

The firewall might mistakenly block legitimate connections a game needs to communicate with its servers. This can lead to connection issues and reduced functionality of your game Overwatch 2.

So, I suggest simply allowing Overwatch 2 through the firewall to lift any restrictions. In addition to the firewall, you should also try whitelisting the game’s installation folder in Windows Defender for safe measures.

Disable Fullscreen Optimization

Fullscreen Optimization is meant to improve the game’s performance in fullscreen mode. However, it can sometimes do more harm than good, as some users report experiencing increased input lag with FSO enabled, especially in fast-paced games such as Overwatch.

This can feel like a disconnect between your inputs and the on-screen action. Which eventually leads to crashing the game. I managed to fix the issue by disabling the fullscreen optimization. The same method was also used to solve other gamers’ issues. 

Disable Third-Party Peripheral Applications

Suppose you have third-party peripheral applications installed, like the Razer Synapse or Logitech Options. In that case, you must disable them while playing the game, as they will interfere with your gaming interface. Not all games are compatible with third-party software like Synapse. 

Sometimes, using third-party peripherals might cause glitches or crashes in certain games. Synapse and other background programs can use up system resources, which can cause some games to perform a little bit worse or have a minor drop in frame rate.

To do this, you must disable these applications and use your device’s onboard memory for configurations. You can launch them back up once you’re done with the game session.

Delete Razer Chroma Sdk.Dll File

If you have Razer Chroma installed, a file linked to it can cause Overwatch 2 to crash. To fix the issue, you need to delete it. Don’t worry; deleting it won’t prevent the game or Razer Chroma from functioning properly. 

Here’s how to do it:

  1. Go to File Explorer > Open the Windows drive (In most cases, it is Local Disk C).
  2. Now, open the ‘Windows’ folder and go to ‘System 32.’

  4. Right-click on the file and delete it.

Keep Windows Game Mode Off

The Windows Game Mode is an excellent feature designed by Microsoft meant to improve your gaming experience by turning things off in the background. However, if Overwatch 2 keeps crashing mid-game, chances are it is because of the Game Mode, as the game mode protects the game from properly running.

Game Mode prioritizes CPU and GPU resources for games, which can sometimes conflict with background tasks or other programs, leading to errors, crashes, or performance issues.

So, I suggest turning it off to see if that solves the issue:

  1. Search for ‘Game Mode’ and open ‘Game Mode Settings.’
  2. Then, click on the toggle button next to Game Mode to turn it off.

Use The Battle.Net Special Command

This next method involves using a specific command in the Battle.Net App. This command can help refresh the game’s servers and prevent further crashing. Don’t worry; this won’t affect the game’s settings.

Here’s what you need to do:

  1. Open the Battle.Net App and click on the gear icon once again.
  2. Click on ‘Settings’ and then access ‘Game Settings.’
  3. Next, check the box next to ‘Additional command line arguments and then enter the following command in the box:
    –tank_WorkerThreadCount 2 -d3d11 -threads 2

  4. Click on Done and launch Overwatch 2 again.

Set Overwatch 2 Priority To Realtime In Task Manager

Task Manager allows you to set the priority of different applications. The higher the priority of the application, the more important it will be in the system’s eyes and the better it will run. It will also stop crashing.

This is how you set the priority to Realtime:

  1. Open Task Manager and click on the arrow next to ‘Overwatch Application.’
  2. Then, right-click on Overwatch and select ‘Go to details.’
  3. Scroll down and right-click on ‘Overwatch.exe.’
  4. Hover the cursor over ‘Set priority’ and select ‘Realtime.’

Fixes For Overwatch 2 Crashing Mid Game

The specific reasons behind Overwatch 2 Crashing Mid Game remain unclear within the gaming community. However, I have attempted to identify and suggest potential solutions to tackle this persistent issue.

Create a Microsoft Account

One potential workaround for resolving mid-game crashes in Overwatch 2 involves creating a new Windows user account. These crashes seem associated with a recently implemented anti-cheat system named Hyperion/Byfron, notorious for causing disruptions for legitimate players.

A notable clue lies in the similarity of crashes experienced in Fortnite, which also utilizes Byfron. This similarity suggests that the anti-cheat system could be triggering the crashes in Overwatch 2 as well. Creating a new Windows user account has served as a popular workaround, allowing players to bypass the crashing issues linked to this specific anti-cheat system.

Disable Overclocking

Overclocking can certainly give you an edge in games regarding your frames and performance. However, disabling overclocking has proven effective among several players for fixing crashing and stuttering in the game on PC. You can disable overclocking very easily by using the MSI AfterBurner application.

  1. Start by launching MSI afterburner.

  2. Now, simply adjust the Memory and Core clock to +0.

If you have an NVIDIA graphics card that is greater than the Gtx 16 and Rtx 20 series, then you can use the Nvidia Geforce experience to tune your clock speeds. However, if you have an AMD card, you can easily use its adrenaline or catalyst software to adjust your memory and clock speeds.

Disable Radeon Boost

To address mid-game crashes in Overwatch 2 linked to AMD Radeon 6000 series cards, a potential solution involves disabling Radeon Boost in the AMD driver settings. Reports suggest that these specific graphics cards encounter random crashes while playing Overwatch 2, and often, disabling Radeon Boost resolves these issues.

Radeon Boost is a feature within AMD drivers designed to enhance performance by adjusting resolution dynamically. However, it might be causing instability in Overwatch 2 for some users. To apply this fix, access your AMD driver settings, locate the Radeon Boost option, and disable it.
