Hi, first of all i will list you my computer specs:
GPU = Zotac RTX 3080
CPU = Ryzen 9 3900X
MEM = 16 GB 2666MHz CL16
HD = 2 x 500GB SSD
I have some troubles in games, especially PUBG with low fps ( ive seen test at youtube it should have around 150-200 fps) at 1440p ultra + alot more gpu usage.
in my setup my gpu works between 30% to 60% most of the time.
cpu is laying between 20% - 45%
i dont believe there is bottleneck in my setup. Ive been reading in and out on forums and youtube about this issue.
