High CPU Latency despite low CPU usage

My game will be running smoothly but every now and again my cpu bar on the performance graph will spike up to 10+ ms and cause the game to stutter. The stuttering isn't reflected on my fps counter but it is really, really annoying. It would make since if it was caused my cpu under-performing, but according to both task manager and AMD ryzen master my cpu usage hovers around 40%. My shader bar on the graph also tends to spike up like crazy occasionally. I have only had this problem with PoE2, I have not tried playing PoE1 on this computer yet.

My Specs are:
AMD Ryzen 7 7700 8-Core Processor @4.80 GHz
Nvidia RTX 4060 8GB
32GB RAM
The game is installed on an SSD

I'm also using an ethernet connection, I have to connect to the California servers and average around 50 ping.

I have tried changing around my in-game settings many, many times and pretty much nothing has made an noticeable improvement. Even lowering all of my settings as low as they go did not help.

I have also tried other solutions that I've seen in other threads like setting my PC's power plan to maximum performance, changing my power management mode in Nvidia control panel to maximum performance.

I would really love to play more of this amazing game but the stuttering is really starting to get to me after putting up with it for my 48 hours of game time.

Stuttering every 30-60 seconds

did you ever find a solution to this?

Hello,

I have the same issue with my cpu ryzen 7 7800x3d.

CPU latency sits at 2ms in town then spikes between 20/10ms every 5-10 sec.

Fun fact: also happens in the Main menu and also happens in PoE1.

I've tried turning of the c-states, tried changing the chat channel and also tried turning down my cpu power to 80%. Those were the only suggestions I found regarding the same issue. (it worked for some ppl with old hardware)

C-states helped being a bit less noticeable but as at the cost of 100% cpu load. kinda dangerous imo for long hours.

Triple-buffering helps a little bit but still noticeable.
Engine multithreading doesn't help aswell.

Note: if a dev needs a video showcasing all options please DM me

I still have not found a solution. I found that in my case it's very likely caused by just a bad connection with the server. I'm confused because my internet is pretty good, I average 300 Mps download, so it's probably something up with GGG's servers.

Also today while mapping my game hard crashed and locked up my entire PC during a loading screen 3 different times. One of the times even happened after I changed to fullscreen mode as per recommendation of another thread.

fingers crossed their team can iron out some of these performance issues so I can play during the holidays :)

Same issue as of today. Maybe I should pull out an old clunker to play POE on.

Then today I decided to put in the AMD 9800X3D...same issue

running maps with that CPU ms lag status graph...up and down spikes.

Tried changing game settings...etc


Other games do not have the studdering.

Please dont engage with ragebaiters and delete flame posts and responses to ragebaiters. This only polutes the thread and nothing get fixed.Please keep in mind this issue affect ppl with end game rigs.In the past i was able to play full juiced delirium maps with no issues.My rig is fully formated and reinstalled, with latest drivers, debloated system and the issue still persist. Once i kill fisrt pack of mobs, my fps plumets from 120 to 15-20, and cpu latency goes up from 4ms to 40ms and stays there as long the characters is in the area with dead bodies killed by poison.
Shader is not loading, network stable, drive not loading any data yet cpu latency is 40+ and directly corelates to fps loss.

_____________
THEORY:
- shaders and on death corpse effect are the cause

_____________
SYSTEM LOAD DURING GAMEPLAY:
VRAM ~4/16GB,
CPU load ~40%,
GPU load ~80%.

NOTES:

-when i kill the enemies, the cpu latency grow fast and affect other players as well
-when i kill no enemies, but other ppl with different build, this does not happen.
-did small test, got into area with many corpses and the poison death effect on them, fps 25. used detonate dead on all corpses on the screen, fps went up to 115.
- also, when there are only dead bodies (clear map), cpu utilisaiton is 34% and gpu utilisation is 42%, but CPU latency is 27 and fps is 36. So this is definitelly related to the poison death effect (at least in my case)
- tested also with different poison build and as long there is the poison dead efffect on the corpses, this issue persist.

____________
CONCLUSION:

issue seems to be related to shaders and on corpse effects,
this issue persists as long as the dead corpses killed by poison remain on screen. This might affect also other builds but i tested this solely on poison builds. Maybe there is some computation done on the corpse objects which are not handled by GPU but cpu only and thats why this is happening.

____________
PROPOSAL:

as quick fix, before correct, more komplex solution is done, please give us option to not render dead bodies and effects applied to them or similar.
