Departure at the meeting with the Burrers (S.T.A.L.K.E.R.: Shadow of Chernobyl)

That's the problem. I play stalker AP with fashion GUNSLINGER. When you meet the burrer, the game takes off. Understood, the flight is in unsupported resolution. What can I do? supports only 1920x1080, and I have 2560x1080, although the game itself supports this permission, and flies only when meeting with burrers and on some tasks.
