@The_Tibber Overclocking wont give you a night and day difference, maybe a few frames if you are lucky, talking really low single digit numbers to the point its not worth it.
The 3600 is a good CPU but its not this game is so heavy on the CPU that its just crippling.
I went from a 8086k @ 5ghz (6c/12t) to a 12900k (16c/24t) and it was a night and day difference (single core is insane, so is the multi core). Would I suggest buying a new mobo and CPU for this game? No, but it would certainly help.
tl;dr, game is heavy on CPU, 6c/12t with AMD chips are not great with it. Overclocking will give you no actual noticeably impact.
