Developers Striking Distance quickly acknowledged the issue and have now released a patch which they say should improve things.

The patch release was announced via Twitter:

Thanks for your patience.

A PC patch is now available to improve gameplay stuttering issues due to shader compilation.

Jacob raises his pistol at a biophage with tentacles pouring out of its stomach in The Callisto Protocol.

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.

“Thanks for your patience,” starts the tweet.

It’s good news if it’s resolved now.

Presumably they’ll focus on fixes first.
