Poor performance. (Paragon)

Decided to write, maybe someone in the know. I watched the video on the game and installed it, started playing and noticed a sharp and unpleasant drawdown to 54-40 and unrealistic and slowly programas texture. I watched a video from people with a similar configuration - the game flies and the framerate does not drop below 75. I moved the game to SSD - zero sense, decided to lower the settings - the drawdown in place, regardless of settings. In other games or mutations both problems were not noticed again from GOW4 (UE4) is stable 60 without a hint of brakes.
