Just hours after Striking Distance Studios launched The Callisto Protocol, players who purchased the game on PC have already noted that the game performs poorly, with many users experiencing stuttering. Now, the team behind the game is working to fix these issues with a day-one patch.

Today, The Callisto Protocol’s Twitter account announced that a day-one patch for the game’s PC version will be out in a few hours. The team also revealed it has a few additional updates on the way, but did not specify what these updates might include.

While these issues haven’t affected all players, many also reported significant framerate drops, which became especially noticeable when turning corners or entering new areas. A few players with high-end graphics cards still reported poor performance.

Despite the game’s notable performance issues on PC, IGN gave The Callisto Protocol a 7 in our PlayStation 5 review of the game, comparing it to the original Dead Space series and calling it “gratifyingly gruesome, but never quite as great as the series that inspired it.”
