Yea that’s a pretty nice CPU can’t get much better than that other than probably Zen 3… Intel 11th Gen beats it by a hair, really not noticeable. I understand how it can be frustrating with top of the line equipment and can’t get smooth gameplay. I haven’t tried flying around KBOS for a while but since the last updates I’ve been having major issues around KATL. I’ll have to check out KBOS next chance I get and see if I have issues there too.
Edit: Do you have an overclock on the CPU? I’ve seen where people have had issues when doing that. Think it’s mostly issues with stability though not really just the general stutters.
