CPU spike during skill usage

Hey GGG!

Absolutely love PoE2 and congrats for the phenomenal game. Currently in act II and day 2 of playing, first day went with no hitches. However, I started to play again today and I'm now experiencing FPS drops specifically during skill usage. When I'm just walking around in maps or towns, I don't get CPU spikes. I've tried lowering every graphical settings, switching to DX11/DX12/Vulkan, windowed/FS windowed/FS, triple/double buffering, setting affinities in task manager, turning off NVIDIA reflex, vsync on/off, dynamic resolution, DLSS/NIS with and without upscaling, switching gateways but nothing seems to remedy this. This makes the game unplayable for me because I get constant fps stutters during fights.

Hope to see a fix soon. Thanks and keep it up GGG!

I am having almost the same issue. There are quite hard cpu spikes (sometimes more than 300 ms) when I am trying to use several skills in sequence. I thought it was connection issue but I realized it is actually because of CPU (it could be AMD only issue as well since I have Ryzen 7 3700X). I even tried to overclock it to improve the performance a bit but it didn't made any difference. What I realized is CPU usage doesn't even hit 100% and CPU won't even warm up but still it clogs the game somehow.

Possible short term solution that I found on Reddit was to lower maximum CPU usage through windows power management menu (Control Panel -> Power Settings -> Advanced settings -> processor usage or something similar). It seems counter intuitive but it solved my problem. I just set my maximum CPU usage to 90% and minimum to 10% (default settings is 100% for both, and it seems like the source of problem in PoE2) and it work almost perfectly (there are still shuttering here and there but much better than what it used to be).

Sorry for the messy post, I can further help if something is unclear.

Hey chop. I had a go with what you suggested + reinstalling my game. So far so good and smooth. Thanks!

Chopper, I will name my firstborn after you. <3

I didn't have the stutter but was one of the poor souls with the high CPU peaks and over all too high CPU load (sadly enough, after a looooong time with PCs I never checked/knew that setting).
So, the high CPU load is gone, time to yank up my GPU.

Many, many thanks for that tip!

This also somewhat worked for me. But eventually the problem catches back up.

Looks like they dont care, I had this issue from 17th Dec, huge fps spike when taking mana potion, now the game is unplayable.

Hey fellow exiles,

I found this reddit thread that seemed to have make my game a bit smoother and hope this turns out useful for you.
