I have a feeling that it might do with your CPU, just downloaded the game to test it out (recently upgraded to Ryzen 5 5600 from shitty af 4300 fx) and had only one stutter like that (i had them everytime i started the game and for the whole introductory part) Try lowering your graphics settings and resolution to the shittiest you can handle until you go to the main area UPD: Actually nevermind, it's happening because of the buffer zone between the warehous and the first room, BUT it is dependent on the CPU, in this zone this stuttering happens quite frequently, but not as bad as it was on my previous processor, so get some patience and good luck with getting through it - it's worth it, trust me :)
it isnt my cpu i just put the game settings to the lowest and it didnt help and i also just recently got a new pc which runs TJOC perfectly cause i have a AMD Radeon RX 6500 and a AMD Ryzen 5 5500 which should be more than enough but even when i do try to move my mouse slowly to progress the first night (the tutorial night) my charachter does like a full 180 turn around or 90 degree turn which makes it (for me) unplayable no matter what settings i choose or do
im just probably gonna wait for an update that fixes this
