After a complete and working install of FLNV, I've noticed an issue where opening the pipboy or a container will introduce a great deal of stutter when the player turns around afterward. Interacting with the pipboy or container will also cause the game to freeze for a second or two before continuing, and after closing said menu. But the main problem is that it introduces this strange turning stutter until the player has viewed the entire scene again- at which point, the frametimes return to normal. Is there a reason for this? I searched the forums to see if this was a known issue but I haven't found anyone else complaining of this particular problem.
I discovered and corrected another form of stutter when turning in cells with water- something involving water multisampling settings in the launcher, which I disabled. However, this issue happens everywhere. I get the impression that its either reloading the scene graphically whenever you interact with menus, or there are some sort of scripts involving containers/the pipboy that cause this.
I have reproduced the issue on another PC- It so happens that I've gone through the guide twice now, on two different PCs, and I have had this issue both times. I'd appreciate it if anyone knows more. Thanks.
