Can't Run This Game On Medium-High End PC.

I can't run this game on my medium-high end pc.

Specs:

i5 7600k @4.4ghz

GTX 1070 8gb

16gb ddr4 2666 mhz

loaded on a 1tb HDD at 7200rpm 

I've tried reinstalling, setting it to high priority, driver roll back, repairing the game and changing various settings. Even on low settings and 25% res scale i get 45 fps.
