Regarding Stutter/CPU Spikes

POE2 is the weirdest game I ever played. Basically I'm struggling to make the game smooth, I have very bad stuttering. Very likely related to the know issue with multithreading.

So while I was troubleshooting to find a solution (already tested all the potential workaround I found here). I launched a video on Youtube on the background and I find out that made my game smooth and flatten the CPU usage on the graph. Worked the best in 4K resolution on Vulkan and all default settings. So every time I want to play I start a video on Youtube and mute the all thing. Weirdest sh*t ever.

I know there are many people in the same case as me so I make this post to share this strange behavior, maybe it could help someone.

This same issue used to occur on POE1! Check my report here from 2022.

Yes it checks out. The game engine handle badly logical cores from the CPU. In a way or an other when a SMT CPU is solicited by an app that activate properly logical cores, the game engine run better.

It baffle me that is an issue since years! What GGG is doing? I guest that with POE 1 people just turned off multithreading to play, but POE2 is more demanding so that a no go except for high end CPU users.

I'll change my setup soon but from a business perspective it's a bad move from GGG to not solve this problem

Same issue here and seems that many other people have too.
GGG is in "silent mode" about this and also all the "big" Content Creators are not talking about it.
Maybe because they have an "I20 with a 5080 TI with 128 GB of ram", I don't know, I don't care.

My hardware is better than recommended, my drivers are all up to date.
If I don't use spells or if I'm against 2-3 enemies I have no problem.
If I use all the spells (especially flames spell + summoning) and I have to fight 15-20 enemies the game starts to stutter.

These problems are similar to those I already had in endgame with PoE 1.
They copied and pasted same problems, congratulations GGG

Already tried to change upscaling, directx, resolution, turning off/on nvidia reflex and I also tried to change quality of sound.
