So, i tried install the gamepass version on PC. Oh boy it's not looks pretty. Bad performance, unplayable.
Compared with Steam version it's like night and day.

Found the fix, it turns out caused by Razer Cortex. It seems Razer Cortex known to be the cluprit of stuttering on Game Pass PC games. Others who had issue with Razer Cortex: https://www.reddit.com/r/XboxGamePass/comments/q6lms2/back4blood_is_unplayable_stutter/ Hope this help.
