After a long wait, one of 2022's most highly-anticipated horror games, The Callisto Protocol, is finally here. Unfortunately, though, it has proven to be a technical nightmare on PC, where players and critics alike have experienced horrible stuttering issues that make the experience nigh-unplayable and ruin the game's immaculate atmosphere.

With that said, there are some effective ways to improve the game's performance with some tweaks to its settings. These settings won't completely solve the issue, but they'll mitigate it to the point where the game is comfortable and enjoyable to play through. Here's a guide on what to do to improve the PC performance of The Callisto Protocol, as well as a look at why the game is stuttering and when official fixes for the issue are coming.

Why is The Callisto Protocol stuttering on PC?

As reported by the experts over at Digital Foundry, the reason why The Callisto Protocol constantly stutters is because the game doesn't pre-cache its shaders like many other games do. As a result, the game has to compile its shaders as you play, which causes significant performance issues when you play through the experience for the first time. This issue is, unfortunately, unavoidable for now, but the below fixes will help the stutters occur less frequently and less severely.

Until some permanent fixes for the stuttering problem in The Callisto Protocol are implemented, these settings tweaks will help keep the issue at bay. Note that you have to make these changes while in the Options section of the game's main menu, as many settings cannot be accessed while loaded into the game itself.

  • Disable V-Sync (Graphics > General)
  • Set DirectX version to DirectX 11 (Graphics > General)
  • Set Framerate Limit to 60 (Graphics > General)
  • Set Upscaling to AMD FSR 2 (Graphics > Advanced)
  • Set FSR 2 Quality Mode to Performance (Graphics > Advanced)
  • Disable Motion Blur (Graphics > Effects)
  • Disable Depth of Field (Graphics > Effects)

It's unfortunate that you need to reduce The Callisto Protocol's visual quality a bit in order to mitigate the stuttering problem, but thankfully, the game still looks great even with these lowered settings and limitations. 

Note that if you're still having trouble even with these tweaks, it may be helpful to reduce the quality of assets like meshes, textures, and texture filters in the Advanced section of the Graphics settings. You can also try lowering the quality of lighting effects in the Lighting tab. Make sure your system meets The Callisto Protocol's system requirements, too.

The Callisto Protocol's stuttering problem is incredibly frustrating to deal with, but there is at least some good news: the developers at Striking Distance Studios have confirmed that an update to address the issue has been released and is now available. Additionally, players can also expect several more updates and fixes for stuttering down the line.

"Thanks for your patience. A PC patch is now available to improve gameplay stuttering issues due to shader compilation," wrote the studio on its official Twitter account. "After updating, you may see temporary stuttering in the game menu the first time you launch the app. We are working on further optimizations in the days ahead."

We'll update this article when we learn more about future official patches and hotfixes for the stuttering problem. In the meantime, try out the above tweaks and workarounds as well as the new update and see if they work well for you.

The Callisto Protocol is now available on Xbox, PlayStation, and Windows PCs. Despite the game's terrible stuttering, it could become one of the best PC games of 2022 once it's fixed thanks to its incredible visuals, terrifying atmosphere, and tense gameplay.
