2. Disable fullscreen optimizations

It seems that disabling the fullscreen optimization option did work for some users. To do so:

Open the Steam launcher > Click on Library.
Right-click on Isonzo > Click on Manage.
Select Browse local files > Go to Isonzo installed location.
Now, right-click on Isonzo.exe > Select Properties.
Click on the Compatibility tab > Tickmark Disable fullscreen optimizations to enable it.
Once done, click on Apply and then OK to save changes.

3. Run the Game File as an Administrator

It’s also recommended to always run the game executable file as administrator access on the Windows PC so the User Account Control (UAC) can allow all the access properly. Sometimes the system may think you’re trying to run the game without authorizing it. This is a one-time process for each game. Make sure to follow the steps below to do so:

Right-click on the Isonzo exe shortcut file on your PC.
Now, select Properties > Click on the Compatibility tab.

Make sure to click on the Run this program as an administrator checkbox to checkmark it.
Click on Apply and select OK to save changes.
You can just double-click on the game exe file to launch it.

Once done, you can also do the same steps for your specific game launcher (E.g., Steam and Epic Games Launcher) used to run the game. So, you’re giving the same UAC access to the game launcher too.

4. Update Graphics Drivers

You should try checking for the graphics driver update on your Windows PC and installing the latest version to ensure no update is pending. An outdated or missing graphics driver can trigger issues with properly functioning graphics-intensive programs. To do that:

Right-click on the Start Menu to open up the Quick Access Menu.
Click on Device Manager from the list to open the interface.
Now, you’ll need to double-click on Display adapters to expand it.

Device Manager Update Display Adapter

Then right-click on the dedicated graphics card name you’re using to bring the context menu.
Next, click on Update driver > Choose Search automatically for drivers.
The system will automatically check for the available update.
An update will automatically download and install the latest version if available.
Once done, make sure to restart your PC to apply the changes.

If you cannot find any update, then make sure to head over to the official graphics card website and search manually for the latest update. If a new version is available, just download the file on your PC and install it. Whatever graphics card you use, jump to the link below as per the manufacturer.

Finally, select High Performance from the Graphics Settings option > Reboot the PC.

8. End Background Processes

The chances are high that somehow your system becomes laggy or gets overloaded by a lot of unnecessary background running tasks. These tasks basically consume system resources like CPU, Memory, or internet bandwidth which can seriously impact the game launching experience. If those tasks (third-party) aren’t necessary for you then try closing them completely by following the steps below.

Press Ctrl + Shift + Esc shortcut keys on the keyboard to open Task Manager.

End Task Manager

Click on the Processes tab > Make sure to select the task individually that you want to close.
Then click on End Task to close it.
As mentioned, do the same steps for each task that you want to close.
Once done, close the Task Manager window, and restart your PC.

9. Verify and Repair Game Files

Sometimes missing or corrupted game files on the PC may occur some issues with the game application launching properly or start crashing. It doesn’t mean that you’ll always get an error message or warning notice after crashing. A minor but useful game file may get corrupted or missing quite easily. Luckily, most of the game launchers do come with a useful feature to automatically verify and repair game files online. To do so:

For Steam:

Launch the Steam client > Click on Library.
Right-click on Isonzo from the list of installed games.
Now, click on Properties > Go to Local Files.

Click on Verify Integrity of Game Files.
You’ll have to wait for the process until it gets completed.
Once done, just restart your computer.

For Epic Games Launcher:

Open the Epic Games Launcher > Click on Library.
Click on the three-dots icon next to Isonzo.
Click on Verify > Wait for the process to complete and restart the launcher.

10. Adjust Steam Overlay and SteamVR Options

Some Isonzo PC players has also reported that they’re facing the crashing issue a lot. It’s most probably happening to the Steam users and we have a possible workaround to fix it. To fix it:

Open the Steam client on the PC > Click on Library.
Right-click on Isonzo from the left pane > Select Properties.
Now, click on General > Make sure to Turn OFF the Enable the Steam Overlay while in-game option.
You should also Turn OFF the Use Desktop Game Theatre while SteamVR is active option.

11. Delete Temporary Files from System

It’s also recommended to manually delete all the stored temporary files from the system by following the steps below. Maybe a corrupted temporary file or dump is conflicting with the actual game to run properly.

Press the Windows+R keys to open the Run dialog box.
Now, type %temp% and hit Enter to open the Local Temporary folder under AppData. [C:\Users\Username\AppData\Local\Temp]
Here you’ll see a bunch of temporary data files listed > Just press the Ctrl+A keys to select all files.
Then press the Shift+Delete keys to permanently remove those temporary files.
Some temp files may not get deleted. So, just skip those files, and delete the rest of them.
Once done, you should restart the computer to apply changes.

12. Adjust Nvidia Control Panel Settings

As per the recommended Nvidia control panel settings, we’ve provided some adjustments that you should also try at your end in case, the Isonzo game is crashing a lot. This method is only applicable to Nvidia graphics card users.

Right-click on the desktop screen (blank) to open the context menu.
Now, select Nvidia Control Panel to open it > Select Manage 3D settings.
Click on Program Settings > Select Isonzo from the list. [If not available, click on Browse and add it to the list]
Make sure to change or adjust some of the settings mentioned below:

- Texture filtering – Quality – Performance
- Threaded optimization – On
Once done, save changes, and reboot the PC to change effects immediately.

13. Disable Windows Firewall

If in case, you’re using the default Windows Firewall protection on your PC then you should turn it off temporarily and check for the issue again. To do this:

Click on the Start Menu > Type Firewall.
Select Windows Defender Firewall from the search result.
Now, click on Turn Windows Defender Firewall on or off from the left pane.
Select the Turn off Windows Defender Firewall (not recommended) option for both the Private & Public Network Settings.

Finally, restart your computer.

14. Turn Off Antivirus Protection

You can also try turning off the Windows Defender option on your PC to ensure there is no antivirus software blocking the game files to run properly.

Press the Windows + I shortcut keys to open the Windows Settings menu.
Click on Update & Security > Click on Windows Security from the left pane.
Now, click on the Open Windows Security button.
Go to Virus & threat protection > Click on Manage settings.
Next, you’ll need to simply turn off the Real-time protection toggle.
If prompted, click on Yes to proceed further.

If in case, you’re using any other antivirus program on your PC then make sure to turn it off.

15. Set High Performance in Power Options

Mostly the Windows system is set on the default Balanced Power Mode which offers both performance and power consumption at the same time. But sometimes, this mode can occur performance issues on your PC when it comes to graphics-hungry programs. It’s better to set the power mode to High Performance, which can improve the tasks. However, this mode will consume more power or battery juice than normal. To do this:

Click on the Start Menu > Type control panel and search for it.
Open Control Panel from the search result.
Now, go to Hardware and Sound > Select Power Options.
Click on High Performance to select it.
Once done, make sure to reboot the PC to apply changes.
It might fix the Isonzo crashing issue on your PC.

16. Reinstall Microsoft Visual C++ Runtime

If your Windows computer isn’t running on the latest version or somehow the required version of the Microsft Visual C++ Runtime then you may encounter several issues whatsoever. To do that:

Press the Windows key from the keyboard to open the Start Menu.
Now, type apps & features to search.
Open Apps & Features from the search result.
Click on the Microsoft Visual C++ program(s) from the list individually.
Select each program and click on Uninstall.
Follow the on-screen instructions to complete uninstallation.
Next, visit the official Microsoft website and download the latest Microsoft Visual C++ Runtime.
Once done, install it on your computer > Restart the system to change effects.

17. Perform a Clean Boot

As per some reports, multiple programs are always running in the background from when the Windows system boots up. So, those services may consume the system resources and internet data without your knowledge. It’s better to perform a clean boot and turn off unnecessary startup applications by following the steps below.

Press Windows + R shortcut keys to open the Run dialog box.
Now, type msconfig and hit Enter to open System Configuration.
Go to the Services tab > Enable the Hide all Microsoft services checkbox.

Click on Disable all > Click on Apply and then OK to save changes.
Now, go to the Startup tab > Click on Open Task Manager.
Click on the Startup tab from Task Manager.
Make sure to click on the particular task which has a higher startup impact.
Once selected, click on Disable to turn it off. [Do the same steps for each program that has a higher startup impact]
Finally, make sure to restart your computer to apply changes.

18. Try Disabling Overlay Apps

Sometimes a couple of applications may come with an additional overlay app that helps the streamers or gamers a lot. However, these overlay apps can eventually conflict with the game files to run smoothly and may cause FPS drops, black screen issues, lags, glitches, etc. You should try manually disabling the overlay apps before launching the game to cross-check whether the crashing issue has been fixed. To do so:

Disable Discord Overlay:

Launch the Discord app > Click on the gear icon at the bottom.
Select Overlay under App Settings > Turn on the Enable in-game overlay.
Click on the Games tab > Select Isonzo.
Finally, turn off the Enable in-game overlay toggle.
Make sure to reboot your PC to apply changes.

Disable Xbox Game Bar:

Press the Windows + I keys to open Windows Settings.
Click on Gaming > Go to Game Bar > Turn off Record game clips, screenshots, and broadcast using the Game bar option.

Disable Nvidia GeForce Experience Overlay:

Launch the Nvidia GeForce Experience app > Head over to Settings.
Click on the General tab > Disable the In-Game Overlay option.
Finally, restart the PC to apply changes and launch the game again.

Some other overlay apps can cause trouble for you something as MSI Afterburner, Rivatuner, RGB software, etc. You should turn them off as well.

19. Disable CPU or GPU Overclocking

It’s also worth mentioning not to enable CPU/GPU overclocking on your PC if your game is crashing or stuttering a lot. We can understand that overclocking CPU/GPU can make a huge impact in improving gameplay but sometimes it may also cause issues with the bottleneck or compatibility too. Just set the frequency to default for optimal performance.

20. Update Isonzo

Even an outdated game patch version can trigger several potential gaming device issues that lead to crashing issues, lags, stutters, and more. It’s recommended to check for the game update periodically and install the latest update whenever available. You can follow the steps below to do the same.
