So i have since maybe beyond light constantly fps problems which appear and then dissappear. Ive triet many many things especially related to AMD which i use and in future wont anymore xD But at this moment im playing and there are only about 1/10 of other players online and lol i have everywhere constant 60 fps. So weather its a thing related to my Internet Provider (vodafone/unitymedia) OR its on your side Bungie. If others of you players experience this now too pls comment the more the bigger the 2nd reason it the cause :D
