The last couple of weeks I'm encountering a lot of lag on PC, best noticed by laggy response to input. This happens in all activities, but not consistently. I've already checked my internet-connection but since there are no other devices using up enough bandwidth to choke the connection either up- or downstream, that's not the issue. Also no other programs using up resources on my gaming PC. The last couple of days I also experience issues with bounties in activities, like the current issue in Crucible. In strikes, when going into a new area, if a bounty just completed, I get stuck 'loading' and that doesn't resolve itself until the game catches up that a bounty has completed (which can sometimes be triggered by going into pursuits). This issue also happens in other activites, such as forge runs.
I have this exact same issue on PS4 Pro. Tried fully resetting console and all network equipment, no change. Primarily during strikes.
