AMVI_Rider Posted December 30, 2019 Posted December 30, 2019 Some days ago I decided to upgrade my MB BIOS and I started experiencing some problems of microstuttering and buzzing noise every some seconds. I did a quick search on the forum and tried almost anything "recent" on the matter but with no success (mouse update, hot-plug disabled, ...) I'm pretty sure that the BIOS update was causing the problem so this evening I started playing with power profiles and CPU priority/affinity. Many comments about microstuttering found on internet were referring to core parking and the need of disabling it by selecting the High Performance power profile for the CPU ... not in my case. I then installed Process Lasso and tried playing with process CPU and I/O priorities, nope. I then ended with manually selecting the CPU affinity and noticed that by just deselecting CPU0 in the affinity the problem disappeared. Note that doing the same with any other CPU available had no effect. The video below demonstrates how by simply deselecting the CPU0 solves the problem in my case, but I'm really puzzled. Note that instead of the buzzing sound OBS is capturing silence, so, the stuttering is less evident, but still noticeable also in the images. I'm posting because it may help someone else, but I'm also trying to understand how just CPU0 can affect the sim in such a way. My system is a Ryzen 5 3600x (6c/12t) - 32Gb 3200 C14 - X570 AORUS Pro (BIOS F11 - 1.0.0.4 B).

cochise Posted December 31, 2019 Posted December 31, 2019 I was having the same microstutters issue with decent frames ( 45+) in vr and it was killing the Immersion for me. Every 10 to 20 seconds the visuals and sound would stutter. I read strongharm's post about having a new powerful rig with bad performance and went through his steps. I also noticed spikes in my ethernet that coincided with the microstutters occurring. Strangle enough for me it was razer cortex! I have no idea why, as it had helped me so much in the past. Disabled it and back to fluid game play. Obviously I tested turning it back on and with it came the microstutters. Sent from my MAR-LX1M using Tapatalk
AMVI_Rider Posted January 2, 2020 Author Posted January 2, 2020 I tried closing / disabling anything I have running but doesn't change the behavior in my case.

rinkerbuck Posted January 14, 2020 Posted January 14, 2020 Saying this is probably bad luck, but the "repair DCS openbeta" from the start menu seemed to fix this for me. GOD PLEASE DONT GIVE THEM BACK TO ME TONIGHT
rinkerbuck Posted January 16, 2020 Posted January 16, 2020 aaaaand the shit started happening again last night, FML. Repair option is no longer fixing it.
