Hi everyone! I finally got to play AC IV.

As with every previous one (AC, AC2, AC:B, AC:R, AC3, AC:Lhd) I expected to play AC4 at ultra settings at 60fps, but I barely pass 40fps and dropping to under 30 all the time, making it impossible to play.

I've searched everywhere and I found no answers, I have quite more than the recommended specs, still can't run it smoothly:

ASUS SABERTOOTH FX990 AM3+
AMD Phenom II x6 1075t @3Ghz
8Gb DDR3 @1333Mhz (Generic manufacturer)
Zotac NVIDIA GTX 970
2TB HDD
Windows 10

I've read threads from the year AC4 was released and people could play it at 60fps with less hardware than I have.

Any tips?
