i can confirm 2 improvements that were suggested here, at least in my experience.

first of all i have an old system Q9650/4 cores, oc to 3.3 ghz, gtx 970 -bios oc. micro stutter seems to affect cpu rahter than gpu. gpu is barely breaking sweat.

i can run the game in ultra no probem, only in act 2 , was it riftwood or riverwood town basically where stutter becomes more of an issue. so i tested these two things,

first one probably didnt help that much, but in my opinion, application/ services that should not be running in "windows" when playing a game, really should be stopped anyways, someone posted the:

disabling Windows Game Bar / Game DVR line codes, i copy-pasted these to cmd admin, all good!

second one i think really minimized micro stutter to mini-mini stutter was:

when in-game, going to task manager, changing the core used by this game to 1 and then back to 4, before this the game used mostly 2,3,4 cores, not core 1. but after this change, its all leveled and i believe that even if the game does not use more proccessing power because of that, the cores 2/3/4 are now more freed up and are able to smoothly proccess windows proccesses that were assigned to cores 2/3/4, so this is i believe the biggest benefit i see when playing now, even in heavy proccess areas, there is way more smoothness to the game..

overall great game!! i bought div2 after div1ee, so lost of fun..

cheers,
