Performance problem potential temp solution

Since the new engine improvements everyone has had performance problems.

While mapping one night I got annoyed and decided to mess with stuff to see if I could make it any better. To my suprise I found that disabling one of my cores using the Set affinity in task manager resolved my performance problems.

I am making this post because I would like other people to try changing their affinity settings on the PathOfExile.exe process to see if it improves their performance.

System settings (my old slow pc)
CPU: i5-4xxx (not home) old quad core no hyper threading
GPU: Nvidia 650ti Boost
RAM: 16GB
Resolution: 1440X900
Renderer: Vulkan
FPS locked to 29

with cpu, 0,1,2,3 checked fps is 4 to 14 with cpu ms going from 40ms to 400ms
gpu ms is always around 23ms

with cpu, 0,1,2 checked fps is where I locked it at 29fps with cpu ms from avg 60ms

Those of you with 8 core or 16 core Ryzen cpu's try affinity with 3 cores close to each other (try to keep it in the same die/ numa node)
Those of you with newer intel cpu's with E cores and P cores try and set affinities for P cores (close to each other in numbering order.

----EDIT----
I just came across a post from NukezzUU posted on aug 28 with a similar experience. (I dont know how to link the exact response)

I think you are on to something. While this created for me a horrible stutter, and drop from a regular 144 to 90 and below, I stopped experiencing ms spikes.

However it was not a solution for me as the game now kept freezing and stuff, so I went back to affinity on all cores, with stable 144 fps but latency spiking from 50 to 500.

Im on a Ryzen 5600x with rtx 3070.

Thank you for trying it out and reporting back your results.

I'm sorry it did not work for you, but its good to hear that it did reduce the cpu ms.

I suspect your frame drops and stuttering was because those extra cores are needed to run at those high framerate but the engine is having trouble efficiently scheduling its work on more cores causing the high cpu ms.

This is not a solution, it's another fake fix that does nothing, posts like these aren't helpful they are annoying because they don't solve the problems at all this is like suggesting to delete system32 to solve problems, like yeah it does but only because your PC is broken, and unusable from that point on.

But they want to help dude. Don't be rude.

Now seriously, some people need to understand that they do more harm than good with their advice.

Some "fixes", especially on reddit make your CPU run on full speed constantly which could result in hardware problems.

It's madness to argue with some people here.

It's not that hard to use hardware properly and make use of the pretty simple and even self explained ingame settings.

your cpu and gpu arent human, it doesnt matter if its 50% or 100%. I mean thats why u bought it, to use it, not to underuse it?

I think to say this does more harm than good is an understatement, this not only does more harm because it makes it seem like there is a semi-solution to a real problem that doesn't exist.

It also comes with the additional problem of GGG staff possibly looking at it, and then doing less to actually resolve the problems, which is not something I know for certain, but it does seem that way from the player's POV.

When you are looking for actual solutions another thing to try certainly isn't bad, but when it comes to something like this where you make everything worse instead of solving anything the intent becomes irrelevant since not only is this a non-solution, this is a bad thing to do either way.

If there is a default problem with the CPU or GPU it might be helpful
(but that is not the case) for everyone with these problems, other CPU or GPU-intensive games run smoothly, and there were no such problems during the Crucible league.

Yea we've been reporting this multithreading bug on some intel CPU and AMD Ryzen, there is no "real fix" as this is something on GGG side to fix with the coding, you just have do any of the workaround (see which one works best for you) if you want to play until they fix it.

I don't think this is due to multi-threading, I think it is a problem with shaders, the aforementioned possible workarounds don't solve anything.
