скачет ФПС в играх

Good afternoon. Recently I purchased an RX 580 card and faced such a problem, FPS drops in games, drops to 12 and in 5 seconds it returns to its original state. Tried all drivers with a "clean" installation. AMD FX-8320, 4000 MHz, DIMM1: Kingston HyperX KHX1866C10D3 / 8G, Radeon 580 8gb
