We are seeing incredibly low GPU performance for Destiny 2.
5000 series owners have been able to revert to older drivers for a fix, while people with 6000 series have no option.
I made a big thread about it on the AMD Reddit also: https://www.reddit.com/r/Amd/comments/m5chj0/psa_if_you_play_destiny_2_regularly_do_not_buy_a/
