High CPU latency
|
I've tried playing PoE 1 on my work laptop last year and had bad performance, but I guessed it had something to do with the laptop, but I can play diablo and Last Epch perfect, so that makes me think it's a setting or something specific with PoE. The CPU latency keeps fluxuating between 20-100 Latency, and because my computer says it's only being used for 40-60 %, I would assume it's not the CPU
Laptop Model HP zbook Firefly G10 I7 1533U 32Gb Ram RTX A500 I've got to add that this has been an issue the last league as well, so nothing specific about this league. I've also tried following things: - Change powermanagement settings in BIOS since this would have been a know issue with my laptop model and HP messing with the powersettings - changing api, dx11 works best, vulcan and dx12 are trash - changing the shader cache location to a different partition in my hard drive (I only have one) using the link cmd command line - closing some apps, I closed riva turner and cpu park control - manually changing preferred gpu in both nvidia settings and windows graphics settings - changing the graphics settings, they're all at their lowest. engine multithreading on/off didn't help, neither did triple buffering - I've lowered the resolution and scaling to the lowest and still the same performance - disabling the integrated graphics makes performance even worse. None of the above fix the issue, CPU latency stays high, disabling the integrated graphics makes performance even worse.  Last bumped on Dec 9, 2025, 11:27:30 PM

Path of Exile 2's Patch 0.4 later this week apparently contains quite significant improvements to how the game runs on the CPU, which might be especially helpful for U-series CPU models.
https://www.pathofexile.com/forum/view-thread/3883495#generalimprovements Assuming it doesn't spectacularly blow up in GGG's faces somehow, such engine improvements should make their way to the original Path of Exile during a future league launch. Because the two games run on different versions of their proprietary engine, it's difficult to say guess at the workload to backport them when 'looking in the window', so to speak. Other than waiting, the only thing we can really do in the meantime is try to work around the issue. I have to admit that the 1355U's paltry 12 MB of cache isn't inspiring me with confidence. Path of Exile has always been notably CPU-bound, whereas other titles such as Last Epoch tend to be more reliant upon the GPU for their framerates. Different games; different engines. My first course of action, if I were you, would be to download, install, and run the free version of HWMonitor. Leave it open in the background as you play, and it will record - among other things - the highest temperature reading from different sensors on your CPU. https://www.cpuid.com/downloads/hwmonitor/hwmonitor_1.60.exe Anytime people speak of oscillating performance in the manner you describe, it's vital that we first seek to establish whether that could plausibly be caused by temperature-induced throttling. If so, overheating could potentially cause physical and irreversible damage to the laptop. If we rule out thermal constraints, then the only real options are seeking to minimise anything else the laptop could be doing in the background, and taking a targeted approach to lowering some of the more CPU-intensive settings in the game's Options menu to lighten the load. Just to set expectations - I don't know well PoE will ever run on a CPU with 2 performance cores. GGG do not offer first-party Technical Support.

" Thanks for all the info but I'm having the problem with poe 1, not 2. Last edited by LocoRojo#3953 on Dec 9, 2025, 11:13:53 PM

" Yes, I know. :) That is why I had said in my original post that they will likely backport the CPU-focused optimisations to Path of Exile 1 sometime next year assuming they work well in PoE 2. GGG do not offer first-party Technical Support.
