EDIT: [b]Fixed, change the "framerate_cap value" in the xml config file (located %appdata%/Bungie/DestinyPC/prefs) to your refresh rate.[/b] Mostly lights/shadows from what I can tell. They flash and make the game basically unplayable (in the sense of it being super distracting). [url=https://i.imgur.com/aZSVKYY.gifv]Here's a GIF of said bug[/url] I have tried: - rebooting - reinstalling old drivers [CLEAN REINSTALL] (397.64 + 391.35 both have the same issue, assuming the rest do as well). - changing graphics settings - restarting the game
