Currently, the game is in an awful state, however, the devs promised they’ll fix it with patch updates. If you can’t wait that long and prefer taking matters into your own hands, the fixes below will help you play the game. Without further ado, let’s dive into the details.
Restart the computer
Restarting is the most generic fix that works most of the time for many games so try restarting your PC and see if it helps. If not, see the next fix below.
Start Oculus app
Many players in the community confirmed that starting the oculus app has helped them play the game. If you don’t have the app on your computer, don’t worry as you can download it through this link. After downloading, launch the app and then start The Callisto Protocol. This will fix the UE4 crash issue.
Edit the Engine.ini file
If the game is refusing to launch, you can make a few changes to the engine.ini file of the game. Head to this location – C:/Users/User folder name/Appdata/Local/CallistoProtocol/Saved/Config/WindowsNoEditor folder. In the WindowsNoEditor folder, you’ll see the Engine.ini file. Open it via Notepad and add the following command at the very end of it- “[/script/engine.renderersettings]r.CreateShadersOnLoad=1”. Save the changes and launch the game.
Run the game as Administrator
Administrator mode can grant access to many features and windows sometimes refuse access to certain functions when games ask to. Running The Callisto Protocol using Administrator mode can fix that. Follow the steps below to do so.
Launch Steam and right-click on The Callisto Protocol, select “Manage” and select Browse local files.
Once you’re in the installation directory, right-click on the .exe file of the game and select “Run as Administrator”.
Repeat the same with another .exe file. It is located in the following path- CallistoProtocol folder/Binaries/Win64/TheCallistoProtocol-Win64-shipping.exe.
Run the game in compatibility mode
If you’re using Windows 11 or 10 and are unable to start The Callisto Protocol, applying Compatibility settings can solve that. Follow the steps on how to do it.

Again, head to NVIDIA or AMD website and download the previous version of drivers for your GPU.

Click on the “Local files” tab and then select “Verify the Integrity of Game Files”.
Let it complete and launch the game and see if there is any improvement or not.
Run the game on a Dedicated graphics card
This is a workaround specifically for gaming laptops with dual graphics cards. If you are unable to play The Callisto Protocol at a higher FPS, then chances are it’s using the Integrated graphics. Here’s how to fix it-
Type Graphics Settings in the windows search box and click on it.
Click on Browse and navigate to the path where the game is installed. Once you found it, select the .exe file of The Callisto Protocol and click on Add button.
After adding the game, click on the Options button and select “High Performance”, and click on Save.
Repeat the second step and in the game’s directory, open Callisto Protocol/Binaries/Win64/and select the .exe file in it. Click on Add and repeat the third step for it as well.
Perform a Clean Boot
Type System Configuration in the search box and click on it.
Go to the Services tab and click on the “Hide all Microsoft services” and “Disable All” button
Click on Apply and Ok and then restart your PC and launch the game.
Turn off Steam Overlay and close all overlay apps
Disabling Steam Overlay and other overlay apps like Discord, and Geforce Experience can also help you improve the performance of the game.
Increase the Virtual Memory
Type “View Advanced Settings” in the search box and click on it.
Click on the Setting button in the performance tab and click on “Advanced” and then click on “Change”.
Untick the “Automatically manage paging file size for all drives” and tick the “Custom Size”.
If you have 8GB of RAM, calculate 8 x 1024 = 8,192, and multiply it by 1.5 = 12,288. If you have 16GB RAM or higher, calculate it and put it in the Initial size (MB). The minimum is 1.5x and the maximum is 3x so calculate it and put the corresponding values.
Once you’re done, apply the changes and then start the game.
Install the latest C++ files
Having the latest C++ files is mandatory if you wish to run any PC games without any problems whatsoever. You can get the latest C++ files from here. Download the x86 and x64 versions of Visual C++ files and install them. If you have already installed them, click on the “Repair” option.
Disconnect external devices
Right now the game is bugged to the point where a random thing can cause problems with it like the Oculus software. If you have several external devices connected to your PC like monitors, USB devices, and gamepads, unplug them and see if that helps. Also, close every third-party application except for Steam and the game itself. If you have an undervolted CPU/GPU, make sure to remove it as well.
If all of the fixes above don’t work, then you can install the game to a different drive or try using Windowed mode. We hope that you enjoyed reading this article. Stay tuned for more updates about The Callisto Protocol, guides, news, and more at Digistatement.
