Yup. And no real customer support from Bungie either on this matter. https://www.bungie.net/en/Forums/Post/242107979?sort=0&page=0 Seems an unrecognized issue.

Ok, I have said this on a bunch of threads and maybe you should check them. Part of the problem is on Bungie's end yes, but a good chunk of this is actually on Microsoft's end. The problem lies in the Creator Update (1709) and the latest security patch that followed. The newest updates are playing havoc with DirectX and are not allowing it to fully sync into the video card drivers. That is creating all kinds of problems including a nasty memory hole. You can resolve this by frequently stopping play and rebooting the game but face it, that's not very viable. The problem is exacerbated by Destiny 2 being a hybrid P2P game. So the problem here is that it takes quite a bit of work on both sides to resolve this problem. It affects not only Destiny 2, but several other games and software (MSI Afterburner, ASUS AI Suite, etc.). There is little that can be fixed rapidly because Bungie could fix their problem but if Microsoft doesn't fix their problem, it will create a bigger mess than we already have. They are aware of it, as are many other game developers, and it is being worked on but all are at the mercy of Redmond at this point.

Before the update today I averaged 90 FPS on highest settings with a 96% Resolution Scale with my 970. After the update using the same settings I average 15 fps. tf happened?
