Look guys this game needs 8 cores, it uses all 8. So if you have a 4 core or 6 core yes CPU usage is going to be high and bottle neck you GPU which is also needing work done from the CPU.. I have ran this game on 6, 8 and 12 cores, my 5800x ran at 30% to 40% CPU usage. My 5900x is around 20% to 30% CPU usage, as for my intel I7 8700k was at 70% to 90% usage with a 5ghz overclock. I know after I played the demo I needed to upgrade, as long as your video card is within the last two gens you should be fine. But if your CPU is less then 8 cores and you want to play in 128 man servers, then CPU upgrade is the best idea. This isn't the only game like this, World of Warcraft is not very GPU heavy. But be in a major city on when a new expansion comes out and see you a CPU usage jump way up to the roof. This is due to the amount of players in the server with you and around you, all this work falls on the CPU. Anyways hope this clears up a few things when it comes to hardware or the need to upgrade, good luck guys and hope to see you in the game soon.
