Bugs, error err_gfx_state and departures of dr. 2. (Red Dead Redemption 2)

Hello, someone tell me what you can do ...
Bought a week ago to myself dred 2 on PC. from the download began problems.
Happiness did not last long, the other day caught the error err_gfx_state err_gfx_state.read about it kind of corrected the removal of the folder of files volcano finale, but after that the problem did not disappear, and began just bacchanalia. ,but now when entering the settings began to fly the same error, just when entering the game began to fly out this error, during the game began to crumble the game.
and forgot to say that it intensified when I just came into the game quietly, but instead of the game I caught a slideshow in 10 frames, instead of 70-80 that were before that .
