[i]Sounds[/i] like the same problem [url=https://www.bungie.net/en/Forums/Post/236633053]almost everybody else is having[/url]. It's easy to mix up with other similar or common issues, so you'll get a lot of dubious advice, including from Bungie. (e.g. mouse polling issue, drivers, hardware issues, background tasks, in-game settings, etc.) But is it happening on any other game you own? If the answer is no... then you've likely got the same problem as a bunch of the rest of us. And nobody has found any way to fix it themselves. Unless someone finds a hacky workaround... we'll just have to wait for Bungie to fix it. But this same issue has been around for a year. So don't hold your breath. Although, it has apparently become worse with Forsaken... so maybe that will move this onto their list of 'unacceptable bugs.' I've even heard that it might be happening to people on xbox as well - which would be telling that it is not something users should be expected to fix themselves.
