The Callisto Protocol is a singleplayer third-person survival game.
The game was released on December 2, 2022. At launch the game was suffering from major performance and shader compilation stutter problems.
A patch released on January 19, 2023, which added New Game Plus (originally promised to arrive alongside a Hardcore game mode on February 7, 2023[1]), general performance improvements and other changes[2].
The December 2 and 7, 2022 patches fixed shader compilation related stutters, that were present at launch, by performing shader precompilation while at the main menu.[3]
The February 7, 2023 added the previously promised Hardcore mode, while improving performance of ray-traced effects and improving the experience on Steam Deck.[4][5][6]

Issues unresolved
Performance is very limited
- Due to the game's CPU utilization being very single-thread limited, the CPU is underutilized (only 2 cores are really utilized) and subsequently performance is severely impaired.[13] The game is even more CPU-limited when running under DirectX 11, resulting in even worse general performance than when using the default DirectX 12.[8] The developers of the game have acknowledged this problem and are working on alleviating these performance issues through several upcoming patches.[14][15]
Stutters while traversing in the game
- The game can stutter when moving around in the environment of the game. This is independent from settings or hardware, and is not shader compilation-related as shaders are pre-compiled for this game since the December 7, 2022 patch. It is likely related to loading.[3]
Game will not launch due to VR hook
- If VR hardware is used, you may be unable to launch the game without its requisite software running.
Workaround: delete VR hook files[16]
