Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition micro stutter/hiccup only in combat!? Pls help :(

Hey all, I am new here and hope to find some sort of solution for my problem in this game. I am really at a loss here..

The Issue

When I am in combat/battle (does not matter how long) I occasionally get a micro stutter or hiccup (like 1 sec delay) when i hit an enemy or when an explosion goes off. The weird thing is somethimes i can get let explosions go off after each other without a problem and then all of a sudden later in the fight or in a new fight i experience this hiccup, whenever i hit an enemy or even when i use lightning bolt and the stun comes up. Everything else runs fine outside combat.

Now I did a lot of google on this issue, read a lot of forum posts.. but could not find something 100% related.

My specs:

I7 6700K
Geforce 980Ti
16 gb RAM
windows on 1 SDD
Steam and the game run on another SSD
Both drives optimized and far from full.
Windows 10
BenQXL2420T (120 hrz)

Things I tried:

- Disable texture streaming
- checked my temps... my CPU wont get above 36 and my GPU wont get above 65 celsius. The rest is fine as well.
- Set pre-rendered frames to 1 in the nvidia control panel
- Reinstall Windows and the game
- Switch in my bios memory between XMP and auto.
- Enable and disable hypertheading.
- set the processor affinity in taskmanager with 0 and 1 out
- set the processor priority in taskmanager to higher vs normal
- Exclude the Eco.exe from the Windows Defender
- Disable secure boot and turn DEP(data execution prevention) off
- enable fullscreen in the game, enable fake fullscreen in the game
- Play arround with the frame limits.
- tried running the exe as windows 7
- set all settings in the game to lowest possible.
- disabled all privacy stuff in windows 10 (that apps can make use of this or that)
- combinations of listed above tried as well.
- Turn of V-synch ingame and force it with Nvidia control panel.

One time i enabled the EVGA precision xoc. (program that came with my graphics card) What I noticed that, during combat when i had those hiccups. I seen the framerate drop from 120 to like 102 or lower (that program shows your ingame fps). But ONLY when hitting an enemy or they hitting me or an explosion or freeze/curse and not all the time, just from time to time.

I am really at a loss why those frames are just dropped sometimes and so randomly? When I run a game like FFXIV and I am in a Raid or dungeon, or when i play Ori and the black forest i get non-stop 120FPS.
The only game that seems to show the same issue sometimes is Pillars of eternity. Now this is a same sort of game but dunno what that has to do with it.

Anyone got an idea what is causing this? Are there more people experiencing this? If it is game-related I might as well let it rest, but a friend plays on a lower system compared to be and does not seem to have the issue...

Help/tips would be really really appreciated.
