Bad "nvd3dum.dll" threads distribution/affinity cause micro-stuttering, bad input lag, mouse sens, some other desync

[Mr-VIT]

PC: i7-7700k (4cores-8threads/(HT on)) + nvidia GTX 970 + win10

At each game start (and sometimes AltTab / map load / change video settings) one randrom of 11 "nvd3dum.dll!QueryOglResource" threads heavy load random logical core

When loaded "nvd3dum.dll!QueryOglResource" thread on same phys.core with one of:

• main thread ("csgo.exe"),

• 2x heavy loaded "tier0.dll!?ThreadProc@CThread@@KGKPAX@Z" thread

  it cause in the game micro-stuttering, big input lag, unstable mouse sensetivity (rawinput On), choppy players animations.

You must set affinity for "nvd3dum.dll!QueryOglResource" threads for execution on the most unloaded core(s) always avoiding phys.core №0 (occupied by main thread)

I also noticed that now "-threads" default = 4 insted of 3(old value). I think this is a bad idea, because "nvd3dum.dll" fifth.

PS: sorry for my english.

@frozendawn

what should i do to fix this problem

wait for CSGO's engine optimization

The problem I described is not the only one. Sound subsystem also has problems. Value snd_mixahead greatly affects the speed of the game (inconstantly).

@Mr-VIT this will never happen cuz i wrote to valve 2 times and they refuse to admit that there is a problem

@Mr-VIT Hi, what is the best value for snd_mixahead ?

[ghost]

[frozendawn]

Re-opened the issue and shared to get more attention, thank you for finding out, I always knew that there is Mouse sensitivity instability and client performance instablility also when leaving the game open for about 2hours, microstutters for 1-2seconds randomly and more ingame performance instabilities, credits goes to you aswell.
