You’re thrown into the Black Iron Prison as Jacob Lee and you have to survive.

You need to defend yourself using weapons, gear, and abilities.

Escape the prison while uncovering its dark secrets under Callisto.

In this guide, you’ll learn how to fix lag, stuttering, or FPS drops in Callisto Protocol.

Why is Callisto Protocol lagging or stuttering?

Callisto Protocol is lagging or stuttering either because your graphics card is outdated or your video/graphics settings are too high.

Decreased performance can also be caused because you’re using Direct X 12 instead of Direct X 11.

An outdated graphics card cannot support the game while high video settings will decrease the game’s performance.

If there are too many players playing the game at the same time, the servers might be overloaded which can cause lag spikes.

Many players are complaining that Callisto Protocol is lagging in its reviews.

How to fix lag in Callisto Protocol

To fix lag in Callisto Protocol, you need to update your graphics card, use Direct X 11, or add a line of code in the Engine.ini file.

You can also try closing all of your tabs and deleting temporary files.

Keep in mind that Callisto Protocol has a high minimum requirement for PC.

The game requires a minimum processor of Intel® Core™ i5-8400 or AMD Ryzen™ 5 2600.

In addition, your GPU needs to be at least an NVIDIA® GeForce® GTX 1060 or AMD Radeon™ RX 580.
