Lag due to CPU spikes in Path of Exile 2.

CPU: Ryzen 7 9800x3d
GPU: 5080
Ram: 32

Constant spikes even with chat off.

Just chilling in 1 spot makes spikes every few seconds.

Returned for 0.2.1 hoping this is fixed, because i literally cannot do pinical bosses with this lag.

If I adjust the game settings from fullscreen to windowed and then back to fullscreen, or if I minimize the window and then go back to the game, I get massive cpu spikes, as represented by the in-game graph at the top of the screen, with frame freezes every 2 seconds or so (also indicated on the same graph). This wasn't an issue for me at game launch or the launch of this league. I'm using a Ryzen 7 9800X3D.

For me it's Chat, also Voic lines from my character or NPC. Everything that gets written in Chat window.

Tried to switch to 100+ chanel - no messeges, but still statters. Changed to 10000+ chanels - no messeges, no statters.
GGG must do less microtransactions and fix more bugs.

This was not an issue back when I played patch 0.1.0. However, the CPU lag spikes became worse and worse as I played through the campaign for 0.3.0

I tried most, if not all, fixes suggested in this thread, and it never solved the problem for me. Fortunately, I found out that it had to do with the UEFI/CSM settings in my PC's BIOS.

I had to switch to the UEFI BIOS Settings (from CSM) to try out the Battlefield 6 beta with friends. After coming back for the 0.3.0 update, the CPU-related lag spikes we're crazy. Changing back to CSM solved the problem for me.
