I have a decent pc I can get 300+ fps in java in 1440p, I play with 170fps cap and it plays really smooth only issue is when I ride a boat and look around with my mouse, everything is jittery/choppy like its 30 fps. If I look around the world using movement keys there is no problem its all smooth. But, if I look around with my mouse it becomes choppy enough to irritate my eyes.
I’ve reinstalled many versions, vanilla version, optifine fabric .. Everything has this same issue. Any help is welcome ^^
