I've been having same issues and posted yesterday and so far I have learned nothing. I have aurora r11 PC with 2080 Ti and 64 bit with 1.5 Ghz internet speed.. I recently did DNS wipe along with IP reconfig after testing my PC and network speed I followed literally every single YouTube video of trying to make destiny performance better and after none of that work I called my internet and spent a couple days yelling at people only to have my router tested to confirm its not my router so I then did a full factory reset on my PC to make sure I don't have any viruses or malware.. and Destiny is STILL constantly disconnecting or crashing yet im told its not them.. ? ? ?
