Hi have the same issues here since last patch, also I managed to convince a few clan members to buy the game when it was on sale (great) and they too are all having high cpu issues with this game and this game only (I am now "popular" lol). 5 machines with varying system specs but all upto date and capable, symtoms include:
black screens
graphic stutter
mic and sound cut outs or distorting,
input lag
failing to load game
slight temp increase
I have noticed the intel users cpu's are pinned to 100% all the time where as the amd users are seeing higher roughly 30/40% higher cpu usage in game compared to last patch but 90/100% in menu and not one pc is overheating a bit warmer up 5-10c adverage but we do all have good coolers though.
Tried all the fixes (thanks btw) but nothing has worked or improved the issue so far, looking at other post's in these forums it seems there is possibly more players suffering this issue without realizing it, please fix 😉
