Patch fixes The Callisto Protocol’s stuttering, which Glen Schofield blames on a ‘freakin error’

Sci-fi survival horror game The Callisto Protocol received an avalanche of negative Steam reviews (opens in new tab) due to a stuttering problem it suffered from at launch. Its user rating dropped to 22% at one point, with players calling it “a mess” and renaming it “The Stuttering Protocol”.

That user rating has now begun rising following a post-launch patch specifically to tackle the performance problem, and is currently sitting at a “mixed” rating of 51%. “Thanks for your patience”, the official Callisto Protocol Twitter account (opens in new tab) said. “A PC patch is now available to improve gameplay stuttering issues due to shader compilation. 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.”
