I have been playing Ghost Recon Wildlands on Steam. My hardware is AMD FX-8350, Radeon Rx 480, DDR3 16 gb of ram. Game runs pretty smooth for the most part, but at random times the game will drop from say 45 fps(average), to 5-12 fps for about 3-6 seconds. then back up to 45 fps. It does this randomly and frequently. The hardware is the recommended stuff from the UBISOFT site. This happens more so on co op then on single player.
