I noticed a quite large reduction in performance in some areas of the map and certain zoom levels once I enabled this mod. This was strange to me as I have a 14900k CPU and 4090 GPU and generally run Rome locked at my monitors refresh rate of 175. I started to look into it more and I noticed that Imperator: Rome seems to have a thread director problem, it was fully loading one of my E-Cores when my P-cores were quite lightly loaded. I also noticed my vcore was much higher then normal(I have my system tuned so it was only getting to 1.35v but generally my chip even when under load is well below 1.3v) I went into bios and switched over to my p-cores only config and this solved the issue right away. My performance was much more normal (175fps with dips when i zoom or move map) and a much more respectable ~1.2-1.25v on vcore.
