Mission lag/Black Screens in bounties.

[Asphyxt]

Every time I've entered a bounty, it'll be fine until the 3rd(?) part then all of a sudden i'll just get hit with a black screen, I have to fully restart my P.C to get out of it.

The first time it happened I thought 'oh maybe I just overloaded' as I recently switched to a 43 inch 4K t.v for my set up. But it's the 3rd time it's happened now and always on the last part of the bounty mission.

The last bounty I was in, was horrifically laggy and literally unplayable, my minimap was bugged, I couldn't see mission objectives only the player nameplates, am I the only one?
