So my config:
Win10
i5 12600k
32GB DDR5
RTX 3050
MSI Z690 torpedo MOBO
Until March I had stable 60-80 fps on Ultra settings.
But after a patch in the beginning of March tha game started stuttering and fps is jumping 20-70 with no relation to the settings (same issues on ultra low).
I ran some tests and found that the game uses 2 p-cores at ~40% and all 4 e-cores at 100%. Those e-cores don't give what the game needs and stuttering starts.
I disabled e-cores in BIOS and the issue was resolved - 100+ fps, no stuttering, all good.
Also I should mention that I have no such issues in other games.
It would be great if Larian could teach BG3 to use P-Cores in intel 12th CPUs so that it wouldn't be necessary to disable e-cores.
