PolishDrunker Battlefield games have always been extremely heavy on the CPU. I'm not an employee or contractor working for EA.
Based on all the past Battlefield games I've played. I don't expect a game patch to lower CPU usage.
I've been bitten by Battlefield CPU issues in the past. I built a brand new i5-6600k desktop PC for Battlefield 1. Only to find out the CPU and memory speed was too slow to prevent fps dips below 60fps in 64 player conquest.
I had to turn around and buy a i7-8700k CPU for $350 and a new Z370 motherboard for $120.
