My SSDs caused the stutter. I don't know if they were close to failing or just not sufficient anymore in terms of reading speed. Since installing a new one everything runs smoothly.

So I've just ordered new parts. When they arrive I'll change parts one by one to see what really caused the problems. Maybe someone with similar hardware can profit from that in the future.

Thank you for the in depth reply. Seems like it's finally time to retire my current rig.

The parameters were just something else I've tried in a long list of possible solutions, I didn't really take time to look into what exactly they would do. Yesterday night I ran memtest86 for a few hours and had zero errors over 10+ passes. I also switched RAM slots and ran them separately. I disabled my on-board soundcard via BIOS and immediately noticed much less stuttering than before. Selectively updating sound card drivers and using older Nvidia drivers had no impact. A failing SSD is something else I've considered so I swapped my System and Arma SSDs - no difference I'm starting to think my mainboard is kicking the bucket.

So after trying Rising Storm 2: Vietnam I can rule out Arma as the culprit. It's even worse in that game.

The only mod I've been using has been JSRS soundpack but since I reinstalled Windows two days ago everything is Vanilla. Yes I've been thinking about it but I'm hesitant to buy new hardware, I will do that as a last resort. Besides, I kinda doubt that my system runs out of memory in virtual reality. Wouldn't there be a difference in stutter between a 100 player KotH server and a pretty empty single player map? The stutter is always there with more or less the same severity. I have no launch paramaters right now and it makes zero difference. Thank you both for helping.

I've just uploaded one in higher quality. At 1:20 min 4 out of 5 shots cause the stutter. This is extremely annoying because it throws off your muscle memory when aiming which bacially makes me lose half of CQC encounters in multiplayer. Graphic settings have no impact whatsoever. FPS fluctuate a bit, sure but it's the freezes I'm trying to fix. Regarding launch parameters I've tried: -nologs -nosplash -world=empty -malloc=system/tbb4malloc_bi -nobenchmark -maxmem ... basically all the ones regarding cpu core count etc. I monitored CPU and GPU parameters while playing and no temperature value was alarming. I did however see my GPU usage drop from ~90% to sometimes 0% which seems to be the cause of the stutter. Seeing as I already swapped out my MSI 970 for an Asus 970 I can pretty safely rule out a defective GPU though.

Hey, lately I've been playing a lot of Arma 3 KotH again and I have an issue with micro stuttering. Irregularly (sometimes a few times in a 10s time frame) Arma has these split second freezes where I'm unable to do anything. I observed that it mostly happens when I or someone around me is shooting. This happens in multiplayer and singleplayer. I recorded a video: https://www.youtube.com/watch?v=KGJhhvIzbh0&feature=youtu.be The video is recorded in 30 FPS but I'm constantly above 100 FPS here. System specs: GTX 970 I7 4970k 8GB Ram 2 240GB SSDs (OS on first, Arma on second) Things I've tried so far: -Clean Windows install -Set Windows sound to different audio quality settings -Change number of in game audio sources -Change graphics settings -Move and/or remove Page file -Set launch parameters -Disable Antivirus and Firewall -Disable BattleEye -Use a Ram-Cleaner -Unpark CPU cores -Disable Hyper-Threading -Change to a different 970 None of these have brought any sort of improvement, not even a little bit. Right now I'm running against a wall because I can't think of anything else I can try.
