Just found some stuff: if i launch my PC with only 5 (or 4) cores working (set in bios) im getting perfectly (3ms) smooth line on CPU latency (F1) on login screen. With 6, 7 or 8 cores scale on Graph goes crazy. HyperThreading disabled. In game still some stutters on 5 cores, but much more rare and has less duration then with 8 cores.
Also on 4 cores i noticed, when F1 Graph enabled in full mode (shows cpu, gpu and other latencies) game goes perfect, constant 3ms. When im switching graph to only network latency mode or disabling it (F1) Fps goes very crazy, even worse than on 8 cores, which i see when enable full graph again, latency spikes are insane.

Your CPU is simply old. Your Xeon CPU is basically equivalent of Intel Core 3000 series (ivy bridge).
While being server-grade, it is of course bit more powerful, on other side, it's target never was game related workloads so it might suffer there.
Additionally, old generation of Intel CPUs were suffering from CPU vulnerabilities (Spectre/Meltdown/L1TF/Retbleed...). Mitigations of these slowed some CPUs to crawl (depending on workload, the performance decrease was over 70%) - at least on Linux, but I imagine the same impact was on Windows as well. On linux these mitigations can be easily disabled, returning the CPUs to their former glory, but being the Linux guy, I am not sure if this can be done on Windows or how easy it is. The improvements you describe (better performance with lower cores and disabled HT) matches the post-mitigations symptoms.
Which brings us to OS. Windows 10 and 11 does not officially support your CPU. While it might work, some features and capabilities might be missing. The Windows server edition on other hand don't support running games (so while they might work, game optimizations present on desktop windows might be missing on server editions).
Moving forward, if you are somewhat familiar with Linux (and only if you are familiar), I would recommend your luck there as even modern Linux still supports your CPU and you can control the mitigations and PoE runs very well via Proton. |

I CAN RUN POE ON 5 of 8 cores in stable 100fps unlocked or with 8 cores with 140 stable fps after some restarts of game. So no, this CPU is much more than enough. Also this problem apeears on on much modern systems (according to redit or this forum). I bet you never worked with Xeon.

Can confirm that performance on mine old ivy bridge CPU is not affected by the mitigations in this particular case, sadly.
