Major dip in FPS

So it seems to be only happening with this game. At some points I can run the game on Ultra settings with 80+fps no problem, but most the time, even on High settings, the game will consistently dip to about 30-49 fps. Now, I know that it is certainly not my PC’s fault, as I run other games at at least 80+ FPS consistently with Ultra setting on (DMC5, The Witcher 3, etc.)

Here’s my specs just in case: GPU: GeForce Nvidia GTX 1080 8GB Gaming Edition
CPU: Intel Core i7-4820k @ 3.70GHz
RAM: 16GB RAM DDR3

And quite frankly, I wouldn’t be too bothered with this issue if it didn’t affect my Versus experience. Game sometimes runs worse than Gears 1 back on 360 and I know for a fact I’m not the only one with this issue.
Steam version, of course. I refuse to get the game on the inferior MS Store.

whats your cpu

OP updated*

Im in the same boat too - just fired it up yesterday after a month or so and my FPS has dropped by 25.

Its also the same in GOW 4 - used to benchmark at 100fps now is 75.
GOW 5 used to be 75 in ultra not its 45 and unplayable. even when I drop the settings down. did you fix it?
