EDIT 1: I've just found something out. if I shoot guns one at a time it doesn't jerk, left or right, but If I shoot together that's when the stutter occurs.
EDIT 2: I've tried my quest with link cable and stuttering is'nt there.
EDIT 3: I tested the Steam version and it's smooth as butter. So it seems there is an issue with the oculus store version and the rift S.
Space pirate trainer seems to be stuttering when I shoot the bots. If I don't shoot its smooth as normal. Same thing happens no matter the settings in graphics options.
AMD 3900x and a 2060 Super.
