Crap, I thought I had a handle on all of this...think I still do, but I do see my frames drop to 45 more and more. I thought it was related to the 3.3 update, which is when it happened more, but I also have been doing much more combat.
So the implication here might be that my CPU (a humble Ryzen 5 2600) is not enough? It never chugs beyond 60% (and rarely that high) so I cant imagine its hitting some wall and telling the game to throttle down to 45FPS. Even though I have a 1080TI its more likely my graphical configuration of my GPU I would assume, since my GPU always runs high in utilization. And lately I am having so much fun the game I have been ignoring configuration and just playing.
In either case we don't make CPU choices in isolation usually. As much as my machine is dedicated to ED and I believe my Ryzen is more than adequate, I recently was asked to edit 4K video. Suddenly my CPU was a wimp!
ED is not CPU hungry - video editing software is!
