Patch 8 introduced these stutters, i have the same ones also when entering druids grove and in act 2 near last light and on the stairs to moonrise towers.
Patch 8 has brought other wierd performance issues aswell.
I have no idea if they upped the requirements or not (I have a 3080/9900k/970evo/16gb 3200mhz)
but certain spots like last light inn on the inside the fps just tanks compared to the outside.Fps and frametime in turn become erratic which makes any camera panning inside appear juttery.
Same thing happend in Act 3 but not at first.Up until the part where you pass the small bridge and are about to get arrested by the robot cutscene the game was fine and smooth.The moment I crossed the bridge it was like I was in Last light INN again.I just couldn't play like this anymore.
I'm wondering if it's some sort of vfx bug causing these issues.Honestly no idea.
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=958795#Post958795 made a thread about all the wierd performance issues I've encountered since patch 8 got released.Kinda ran out of things to try to fix the issue besides getting a much more powerful PC.
Kinda dumbfounded how I've played the game from BETA to patch 7 without any of these performance issues and all of a sudden it's like this.All while using the same computer and settings.
