How to Fix Callisto Protocol Lagging & Freezing Issue in PC?

Gameplay in The Callisto Protocol can suddenly stop working or become choppy, especially during action scenes or when entering new areas. This lag and freezing usually isn’t because of weak hardware, but because the game does a poor job preparing graphics (shaders) and loading new content quickly.

The main reason is bad optimization for DirectX 12. Other causes can include old graphics drivers, missing pre-loaded graphics, or problems with overlay programs like Steam or Discord. This guide will show you the steps you can take to fix lagging issues in Callisto Protocol.

Prerequisites: Check your System Requirements

If your system specifications do not meet the minimum requirements for Callisto Protocol, you may experience stuttering and lag. Before trying any other fixes, make sure your computer meets the game’s requirements. Here’s how you can check your system specifications:

1. Open the “Run” dialog by pressing Win + R together.
2. Type “dxdiag” in the run prompt to open the DirectX Diagnostic Tool.

   

3. On the “System” tab, check the size of your memory (RAM), your processor, and your DirectX version.

   

4. Go to the “Display” tab to see which graphics card you have.

   

5. Click “Exit” and compare your specs to the minimum requirements below:

Minimum Requirements

• 64-bit processor and operating system required
• OS: Windows 10/11
• Processor: Intel® Core™ i5-8400 or AMD Ryzen™ 5 2600
• Memory: 8 GB RAM
• Graphics: NVIDIA® GeForce® GTX 1060 or AMD Radeon™ RX 580
• DirectX: Version 11
• Storage: 75 GB available space

1. Run Callisto Protocol On Low Settings

If you run Callisto Protocol at high graphics settings, the game will load more detailed textures, which can slow down your computer and cause lag. To improve performance, set the game to low settings before you start playing.

1. Launch Callisto Protocol, then go to Main Menu > Options > Graphics.

   

2. Adjust the settings as listed below:

Low Settings

• V-Sync: Off
• Frame Rate Limit: Unlimited
• DirectX: 11
• Full-Screen Mode: Full Screen
• Resolution: Choose the one that fits your monitor (e.g., 1920 x 1080)
• HDR: Disabled
• Gamma: Monitor SRGB
• Lighting Quality: Standard
• Shadow Quality: Medium
• Volumetric Quality: Medium
• Particle Quality: Medium
• Screen Space Reflection: Enabled
• Physical Refractions: Enabled
• Depth of Field: Enabled
• Motion Blur: Disabled
• Subsurface Scattering: Enabled
• Anti-Aliasing: TemporalAA
• Film Grain: Off
• FSR2 Quality Mode: Balanced
• Mesh Quality: Low-Medium
• Texture Quality: Medium
• Texture Filter Quality: Medium

2. Run Callisto Protocol on Performance Mode

Switching to performance mode in Callisto Protocol boosts the game’s frame rate to 60fps, instead of the 30fps in quality mode. This helps eliminate lag.

1. Go to Main Menu > Options > Graphics.

   

2. Enable Performance Mode.

   

3. Restart the game to see if the lag has improved.

3. Delete Temporary Files

Temporary files can take up space on your hard drive and reduce your system’s performance, leading to lag. Deleting these files may help.

1. Open the “Run” dialog with Win + R.
2. Type “%temp%” and click OK to open the temporary files folder.

   

3. Select all files by pressing Ctrl + A.
4. Press the “Delete” key to remove all temporary files from your drive.

4. Close Unwanted Programs and Services on Windows

Background programs and services can consume system resources, causing Callisto Protocol to lag. It’s best to close these unnecessary processes.

1. Open Task Manager by typing “Task Manager” in the Windows Search box.

   

2. Look at the “Processes” tab to see which programs are running.
3. Select any unwanted program and click “End Task” at the bottom of the window.

   

4. Close Task Manager and try running your game again.

6. Verify the Integrity of your Game Files

Lagging can also happen if some game files are missing or corrupted. You can check and repair these files through your game launcher.

6.1. For Steam

1. Open Steam and go to your “Library”.
2. Right-click Callisto Protocol and select Properties.

   

3. Go to Local Files > Verify integrity of game files.

   

4. After the process completes, relaunch Callisto Protocol and check for lag.

6.2. For Epic Games

1. Open the Epic Games Launcher and click the Library tab.

   

2. Find Callisto Protocol, click the three dots next to it, and select Manage.

   

3. Click on Verify to check and fix any corrupted or missing files.

   

7. Change Control Panel Settings

Having high settings in your graphics card control panel can reduce your game’s performance. Adjusting these settings for better performance may help reduce lag.

1. If you have an NVIDIA card, right-click the desktop and open the NVIDIA Control Panel.

   

2. Go to 3D Settings > Manage 3D Settings > Program Settings.
3. Click “Add” and select Callisto Protocol.

   

4. Click “Add Selected Program” at the bottom.

   

5. Set the following for better performance:

• Monitor Technology: G-Sync
• Maximum Pre-rendered Frames: 2
• Threaded Optimization: On
• Power Management: Prefer Maximum Performance
• Texture Filtering – Quality: Performance
• Low Latency Mode: Ultra

Note: AMD users can adjust these settings instead:
